When installing an advertised OEM, and claims to be from the period of same battery as original. Is there any way possible to know it’s not just a fake battery that just looks like the original, when you install it. Is there a date of manufacturing anywhere in the info

I've replaced a lot of Apple batteries of both the user-replaceable and the screwed in type. I've not done a glued-in one-I need to do my 2012 MBA, but given that it's basically an occasional-use backup for me and also both a lot of work and expensive, I've not gotten around to it.

I always use Apple OEM if possible. I've had the best luck with them, and find that even on ridiculously old stuff a "bad" Apple battery will often be in better shape after a year than a no-name replacement.

If, for whatever reason, I can't get an OEM battery, I go with NewerTech. They are the only ones I trust. Looking around now, I have a bit of a project 8,1(early 2011 13") that I was given completely dead. I put a 2012(9,2) LoBo in it, but still needed a battery. I debated about Apple or NewerTech, but knew an Apple battery would be difficult to get short of bribing an AASP to buy one for me :) , so went with NewerTech. The life is at least as good as I remember my own personal 8,1-my first Mac-being when it was new, and it's held that for going on a year now. I've also put a Newertech in a MacBook(white Unibody) and it works great.

I have a bunch of replaceable NewerTechs kicking around also-in MacBooks, MacBook Pros, and PowerBooks. The only one that has given me trouble was in a Titanium PowerBook, which I suspect was because they were selling off old stock when I bought it. It just quit accepting charge one day(well within the warranty period). They replaced it, and the replacement did the same a few months later. A friend bought one around the same time I bought my first one, and went through the same ordeal. After sending both of us replacements, they quit offering them.

Does Coconut battery show manufacturers date of battery or just the MBP? I presume despite what I’ve asked about here, that anyone making a fake battery can fake the name and year readings too?

I am on my second ifixit replacement, each one will go from mid charge to that magical 7%, then hang there for several hours at 7% before dropping more. 33 charge cycles later, most doing the 100-0% conditioning, I am now at 50% and the service battery indicator has come on. The battery is only a month old.

Ifixit has offered to do a full refund on it's replacement of the replacement. I oredered a Neewer battery from OWC because I hate NY :p . How is your Neewer battery progressing...any "instant 7%" issues?

Talk about disappointing, I went with iFixit based on reviews and recommendations here. Got the battery Friday. Installed it, conditioned it (charge, discharge, charge). Battery drops from 65% straight to 7% consistently. I am on four cycles of it doing this and the design capacity per coconut is down to 85% of original. SMC PRAM reset.

I thought I was paying a premium for a quality battery. What a piece of garbage. iFixit has been unresponsive to boot.
My Amazon battery is back in and I am out $100 bucks at the moment. Buyer beware of iFixit.

Moral of story, should have just had Apple do it (which I will now).
[doublepost=1520940081][/doublepost]This is the battery iFixit sent me, just at a $60 premium:

Hey Paul, the battery I got from B&H after the ifixit mess is holding up well. Jeesh, they are either selling my returned battery or they have a batch of bad 7% ers. It's been almost two years I think. I would think ifixit would stop selling these.

Just returned a third MacBook Pro 15" Mid-2014 battery to iFixIt EU. They have a serious problem with a batch of bad batteries. As far as I could tell, the battery logic did not work properly, it would drop to the magical 7% charge level at any time, lose battery health at a rate of 3% per cycle, or even do two cycles per charge cycle! Despite all that, the battery did hold about 94Wh charge, even when it reported 74% battery health remaining. But it's a real nuisance when macOS starts to throttle the CPU for the next two hours because it believes the battery is almost drained. What's more worrisome is that the battery logic allowed to charge the battery at 4 to 5 Amps despite it reporting "fully" charged, even though the full charge capacity reported by the battery logic was obviously wrong. Unless there is some other mechanism to protect the battery from overcharging, it sure sounds like a fire hazard waiting to happen.

The service from iFixit EU was good, quick to respond, acknowledge the problem, and send a replacement battery and a package label to return the defective battery. They did request to allow 15 cycles for the battery to calibrate, so it took a while before I could request another return.

Finally decided that three attempts were more than enough, and they offered a full refund with apologies for any inconvenience. I put in a Mayerinc battery two weeks ago, and 10 cycles in it still works like a charm. Thought about replacing the MacBook Pro with the next release, but I might just keep going with the new battery. It charges at a slower rate than the original Apple and iFixIt batteries, but I'll take that over any failing battery. Previously had quite some success with Yanec batteries. Of course, I might just have been lucky to get a working battery.

Next time, I might just let Apple replace the battery. It is three times more expensive, including the labor fees by the Apple authorised service center nearby, but it's so much less trouble to go through. And expect good quality components, if not service afterwards if anything goes wrong. With that, I'd like to shout out to Apple for keeping their promise of 1000 cycles battery life. I did not expect it would make it that far, but the old battery lasted 1113 cycles before time on battery became "short" (would still get 3 to 4 hours!), and the occasional sudden power loss when charge was getting low.

Will Apple actually service your 2014 MBP? I think it's been 1.5 years since I brought mine in for a battery and they looked at me like I had two heads and told me my machine was vintage. They told me to look on Amazon.

Back in March I asked for a quote on the price for replacing the battery at the local Apple Authorized Service Center, and they quoted a price of around €300 for a Mid-2014 MacBook Pro 15". Not sure if they would replace it today, especially not now the original battery has been removed. Tempting to ask, because the Mayerinc battery failed the day after I made the previous post. Says it has 100% charge, but power cuts out the moment I disconnect the AC charger. macOS won't even properly boot or let me log in without rebooting due to power loss. I'm assuming the battery is actually dead and macOS tries to draw on a little extra juice to turbo boost through the boot and login procedure. No problem with the machine working without battery (although CPU speeds are limited) or with the old Apple battery (only problem is that it lasts about 3 to 4 hours). The current state of third-party batteries is deplorable. Thinking about buying the new MacBook Pro, and when that battery dies I'll gladly spend the exorbitant fees to have it replaced by Apple!

I Googled Top Macbook Pro replacement battery and came across this forum you started. I appreciate you jumping in an taking all these hits for us to figure out the best solution as well as the others.

I read the entire thread and was hoping by the time I got to the end someone would have a good connect on these batteries. It looks like B&H may be the best bet. I noticed you also got referred to Amazon by Apple too. I bought an EGOWAY off Amazon a few years ago that started draining fast after 6 months. Now of course the company disappeared and theres some new top sellers. I've gotten my SSD from OWC, ram and etc. and they seem reputable, (B&H is using the same from what you stated). I also noticed your battery drain is due to it being maxed out on RAM, storage and the recent IOS. Mine is similar minus the IOS update so there may be no hope it seems..

I bought this specific MACBOOK Pro because I use Logic X and Final cut and I heard the option to upgrade made this 1 of the best Macs for better results. Yet it drops from 100% to zero in 30 min. I guess any battery is better then what I have at this point but wanted to get your thoughts on these 2 batteries before I end up ordering via Prime, finding it sucks, returning it and getting 1 from B&H instead. I'm thinking once you had 1 you probably had them all...

https://www.amazon.com/dp/B07J4YYTWS/ref=cm_sw_r_tw_dp_U_x_-4b2Db0C0EMTX
https://www.amazon.com/dp/B077YY2728/ref=cm_sw_r_tw_dp_U_x_s7b2Db07B555P

Also if you can give your latest results with heavy use on that B&H that would be helpful.

Thanks in advance

I see you a Pats fan/Bostonian as well ??

Hello fellow Pats fan! Big game Sunday against America's former team:)

Ok, I checked out he Amazon links and I honestly can't speak to those. There are SO many battery options on Amazon for these machines. But I did go that route before the Newertech B&H battery and the iFixit piece of garbage. My experience with the Amazon battery was that is did not last very long. It started draining fast after one-year. I remember debating and researching all the Amazon options, reading reviews, etc. I can't remember why I chose the one I chose which was an Abyone rated at 6000.

In terms of heavy useage and battery life with my Newertech, I honestly don't run anything that intensive like logic or final cut. I pretty much use Office, Photos, Email, Safari, etc. I can't speak to the life under heavy usage. I am getting about three hours unplugged, sitting on the couch and surfing. My old machine has begun to run hot and the fans do kick in a lot more than it used to. This could be because of the OS that is not supported (Catalina) or my 2133 RAM.

Battery still lists as healthy. Let me know what else I can answer.

A REALLY big game Sunday. Looking forward

You sound like already did all the work for me. I'm going to order from B&H and maybe the cheapie Amazon as a back up. I been using it plugged in for so long that I almost forgot its not a desktop. I replaced my fan at 1 point since it wasn't coming on right but still runs hot just no slowdowns now. Looking fwd to bringing some life back with the Newertech. Thanks for the fast thorough reply. Helpful!

*fingers crossed for Sunday

No problem, it's nice to breath some life into these older machines. They may be deemed vintage by Apple, but mine screams with the SSD and added RAM. I'd yearn for nothing in terms of speed, seems just as snappy as the new ones in the store. No beachballs, Apps bounce maybe once before opening fast.

Good luck and post back with your observations.

Go Pats!

I agree. I see the later overpriced later models and have no regrets about the $350 I paid for this Mac. Even with the amount spent in upgrades. I've had the same results as you with mine. Just wish I could update to the later IOS. Too many incompatible Plugs ins but its cool. Good luck as well. I'll be definitely be posting my results.

Thanks again

The 2014 was discontinued in May 2015, so it will become vintage on May 2020 (or later), according to Apple's own definition of "vintage product".

Back in March I asked for a quote on the price for replacing the battery at the local Apple Authorized Service Center, and they quoted a price of around €300 for a Mid-2014 MacBook Pro 15". Not sure if they would replace it today, especially not now the original battery has been removed. Tempting to ask, because the Mayerinc battery failed the day after I made the previous post.

Hey, I've got a 2014 15" MBP as well, what did you end up doing?

Currently my battery is still at 85% (but going down) and next spring I'll ask for a replacement at an Apple Store, but I'm pretty sure they will refuse if the capacity will be 80% or higher (anyway in Europe Apple's price for a battery replacement is 209€, not 300€).

The whole third party batteries situation looks like a mess to me.
I don't really like the OWC batteries for the Retinas: they look different than the original (and harder to detach), you don't know how many cells they have and they also ship the same model for 2013/14 and 2015 while they should be different.
I trust iFixit because of the very good customer service, but it looks like their batteries are not very good.
Ebay has a lot of batteries sold as "original", but they usually come from HN/China and I don't know if the resellers will ever honur the warranty in case of problems (which are quite common apparently).
Amazon batteries are a bit cheaper than the one from iFixit and the customer support should be very good.

TLDR; no success yet with third-party batteries, still going strong with old Apple battery

iFixit acknowledged they had issues with some of their batteries, therefore there was no problem to get the batteries replaced for free. But after three batteries with the same issue I can only assume I was either really unlucky, or the problem was a bit more widespread than they led to believe, or there are other compatibility issues (Can Apple update the firmware to block third-party batteries, the same some printer companies block third-party cartridges? I did update to macOS Catalina). iFixit seemed confident they could supply a working battery eventually, but since they required at least 15 cycles to let the battery settle in before it could be returned, it would take about two weeks of problematic battery woes before they would ship another replacement. Therefore I decided to try another brand for now. (BTW, the iFixit iPhone battery I ordered at the same time is working excellent).

The first Mayerinc replacement battery did extraordinary well, good built quality and charge capacity around 8500+mAh, slightly over designed capacity of the original battery, giving 9+ hours of light use on a single charge. I was really happy with that, but then the battery failed suddenly ten cycles in (day after I made the post), no clue what happened. I keep a charge log using `pmset -g rawlog` that is written to disk by a LaunchDaemon script on boot. The last entry was when I woke the Macbook by opening the lid before the power cut out. Battery reports it is fully charged, just not supplying any charge. So I switched back to the old Apple battery and there are no issues aside from it being on old battery with about half the original charge capacity. Anyhow, got a replacement for the Mayerinc battery last week, but it arrived fully drained. Not a good sign. Thanks to the charge logs I can see that despite the reported capacity of 8500+mAh full charge capacity, it only charges to a capacity of about 4400mAh, about the equivalent of the 4 hours battery life it provides when idle, doing 7 "cycles" per discharge cycle! Also, the soldering on the connectors of the battery logic board to the battery and the battery connector on this second Mayerinc battery is mediocre at best, so I requested a return. Not sure if I want to try another one of the brand. The first one might have been a fluke, the second is likely just bad inventory management (production date of the flat battery was back in March 2019).

So, I'm back to my old Apple battery again, currently going at 1116 cycles, hovering around 55 to 60% battery health, and at most 5 hours battery life :)

I don't know if Apple or any of their authorised service centers will replace a battery on a machine of which the battery has already been removed. But I don't think they would deny your request to have it replaced at 85%. The battery in my Macbook remained around 80-85% for quite some time before dropping rapidly. I only have a partial log because I did not keep track after Januari this year because it was hovering around 80-85% all the time, but it dropped to 68% around May:

Sample date Cycle count Condition Full charge capacity
2018-01-05 818 83% 7018
2018-01-21 824 84% 7118
2018-01-30 830 84% 7123
2018-02-13 837 82% 6930
2018-02-25 846 85% 7199
2018-02-28 847 84% 7037
2018-04-24 865 83% 6981
2018-10-06 961 81% 6806
2019-01-04 1012 82% 6888
...
2019-05-15 1067 68% 5727
2019–07-27 1111 66% 5572


Currently, I am tempted to buy one of the "original" / "genuine" / "OEM" Apple batteries since the original battery works so reliably. I just don't think they are truly genuine, since Apple does not sell their batteries through regular reseller. I've heard of rumours that some of the "genuine" Apple parts sold online are goods "diverted" from the original supply chain. What is interesting is that there are new condition Apple batteries for sale on eBay that show pictures almost identical to a genuine Apple battery, including a serial number on the battery connector, but I'm going to assume that the picture is not a true reflection of the actual product you will receive. I did find an online store in my country where they supposedly sell an original apple battery, so I am tempted to try that one despite the increased cost (about €130 compared to €80 for Mayerinc/iFixit/Yanec batteries). If it is not a genuine battery, or if it fails, I'm covered by my countries return policy and consumer protection laws, without having to send the battery back to China at almost half the cost of a new replacement battery.

I haven't tried the cheap batteries on Amazon. They are often the same cheap batteries sold on eBay, usually sold through third-party resellers, sometimes even shipping from China or Hong Kong (2-3 weeks delivery), but they might be easier to return to Amazon if there are any issues. Be sure to check the charge capacity of the battery though. There are plenty of cheap batteries sold with a lower charge capacity than the original battery. High capacity Li-ion battery are generally expensive, so there has to be a reason these are so much cheaper.

Let me know if you have any success with third-party batteries, although considering the issues reported here and elsewhere online, I would encourage you to take the hit to the wallet and have it replaced by Apple. It only costs €209 at the Genius Bar in an Apple Store, but Apple authorised service centers may charge extra (shipping, handling, labour fees), hence the quote for around €300. But it is almost guaranteed good quality. Wish I had done that, although at the time it seemed ridiculous to spend so much on a device with a net worth of maybe max €800 resale value, especially since I was expecting to use it at most one or two more years before upgrading. Now I am seriously considering buying the 16" and let someone else worry about finding a suitable replacement battery.

The first Mayerinc replacement battery did extraordinary well, good built quality and charge capacity around 8500+mAh, slightly over designed capacity of the original battery, giving 9+ hours of light use on a single charge. I was really happy with that, but then the battery failed suddenly ten cycles in (day after I made the post), no clue what happened. I keep a charge log using `pmset -g rawlog` that is written to disk by a LaunchDaemon script on boot. The last entry was when I woke the Macbook by opening the lid before the power cut out. Battery reports it is fully charged, just not supplying any charge. So I switched back to the old Apple battery and there are no issues aside from it being on old battery with about half the original charge capacity. Anyhow, got a replacement for the Mayerinc battery last week, but it arrived fully drained. Not a good sign. Thanks to the charge logs I can see that despite the reported capacity of 8500+mAh full charge capacity, it only charges to a capacity of about 4400mAh, about the equivalent of the 4 hours battery life it provides when idle, doing 7 "cycles" per discharge cycle! Also, the soldering on the connectors of the battery logic board to the battery and the battery connector on this second Mayerinc battery is mediocre at best, so I requested a return. Not sure if I want to try another one of the brand. The first one might have been a fluke, the second is likely just bad inventory management (production date of the flat battery was back in March 2019).

So, I'm back to my old Apple battery again, currently going at 1116 cycles, hovering around 55 to 60% battery health, and at most 5 hours battery life :)

I don't know if Apple or any of their authorised service centers will replace a battery on a machine of which the battery has already been removed. But I don't think they would deny your request to have it replaced at 85%. The battery in my Macbook remained around 80-85% for quite some time before dropping rapidly. I only have a partial log because I did not keep track after Januari this year because it was hovering around 80-85% all the time, but it dropped to 68% around May:

Sample date Cycle count Condition Full charge capacity
2018-01-05 818 83% 7018
2018-01-21 824 84% 7118
2018-01-30 830 84% 7123
2018-02-13 837 82% 6930
2018-02-25 846 85% 7199
2018-02-28 847 84% 7037
2018-04-24 865 83% 6981
2018-10-06 961 81% 6806
2019-01-04 1012 82% 6888
...
2019-05-15 1067 68% 5727
2019–07-27 1111 66% 5572


Currently, I am tempted to buy one of the "original" / "genuine" / "OEM" Apple batteries since the original battery works so reliably. I just don't think they are truly genuine, since Apple does not sell their batteries through regular reseller. I've heard of rumours that some of the "genuine" Apple parts sold online are goods "diverted" from the original supply chain. What is interesting is that there are new condition Apple batteries for sale on eBay that show pictures almost identical to a genuine Apple battery, including a serial number on the battery connector, but I'm going to assume that the picture is not a true reflection of the actual product you will receive. I did find an online store in my country where they supposedly sell an original apple battery, so I am tempted to try that one despite the increased cost (about €130 compared to €80 for Mayerinc/iFixit/Yanec batteries). If it is not a genuine battery, or if it fails, I'm covered by my countries return policy and consumer protection laws, without having to send the battery back to China at almost half the cost of a new replacement battery.

I haven't tried the cheap batteries on Amazon. They are often the same cheap batteries sold on eBay, usually sold through third-party resellers, sometimes even shipping from China or Hong Kong (2-3 weeks delivery), but they might be easier to return to Amazon if there are any issues. Be sure to check the charge capacity of the battery though. There are plenty of cheap batteries sold with a lower charge capacity than the original battery. High capacity Li-ion battery are generally expensive, so there has to be a reason these are so much cheaper.

Let me know if you have any success with third-party batteries, although considering the issues reported here and elsewhere online, I would encourage you to take the hit to the wallet and have it replaced by Apple. It only costs €209 at the Genius Bar in an Apple Store, but Apple authorised service centers may charge extra (shipping, handling, labour fees), hence the quote for around €300. But it is almost guaranteed good quality. Wish I had done that, although at the time it seemed ridiculous to spend so much on a device with a net worth of maybe max €800 resale value, especially since I was expecting to use it at most one or two more years before upgrading. Now I am seriously considering buying the 16" and let someone else worry about finding a suitable replacement battery.
Thank you very much for your answer, it's much appreciated.
Are you from Netherlands (I can't find batterie from the brands you mentioned here in Italy)?

I think I'll wait until next spring to go asking to an Apple Store, the battery is still decent now.
Considering your experience I think I'll still go with iFixit in case Apple refuses to do a replacement. It looks like they stand behind their products and offer a good customer service, which is apparently the most important thing (since literally every battery is hit or miss out there)...
Did they make you pay for the shipment when you gave the batteries back?

(I didn't know about the extra price of AASC, my apologies!)

I Googled Top Macbook Pro replacement battery and came across this forum you started. I appreciate you jumping in an taking all these hits for us to figure out the best solution as well as the others.

I read the entire thread and was hoping by the time I got to the end someone would have a good connect on these batteries. It looks like B&H may be the best bet. I noticed you also got referred to Amazon by Apple too. I bought an EGOWAY off Amazon a few years ago that started draining fast after 6 months. Now of course the company disappeared and theres some new top sellers. I've gotten my SSD from OWC, ram and etc. and they seem reputable, (B&H is using the same from what you stated). I also noticed your battery drain is due to it being maxed out on RAM, storage and the recent IOS. Mine is similar minus the IOS update so there may be no hope it seems..

I bought this specific MACBOOK Pro because I use Logic X and Final cut and I heard the option to upgrade made this 1 of the best Macs for better results. Yet it drops from 100% to zero in 30 min. I guess any battery is better then what I have at this point but wanted to get your thoughts on these 2 batteries before I end up ordering via Prime, finding it sucks, returning it and getting 1 from B&H instead. I'm thinking once you had 1 you probably had them all...

https://www.amazon.com/dp/B07J4YYTWS/ref=cm_sw_r_tw_dp_U_x_-4b2Db0C0EMTX
https://www.amazon.com/dp/B077YY2728/ref=cm_sw_r_tw_dp_U_x_s7b2Db07B555P

Also if you can give your latest results with heavy use on that B&H that would be helpful.

Thanks in advance

I see you a Pats fan/Bostonian as well ??

I would say your battery's temperature can tell you everything you need to know about its condition.

Will Apple actually service your 2014 MBP? I think it's been 1.5 years since I brought mine in for a battery and they looked at me like I had two heads and told me my machine was vintage. They told me to look on Amazon.

Same, told me anything over 5 years they won't touch. And also quoted it as 'Vintage'.
That's Apple London UK, but suspect same in the US?

Going to chip in here:

I have a late 2013 15" retina MBP and I changed the original battery for a duracell direct battery (2-power branded) and when I received it, I had 8500mah. After 173 days I'm now at ~3329mah.

I'm biting the bullet and getting it replaced by Apple. I recently chucked (in the correct manner) the old original out so I may be out of luck getting a refund from duracell direct :(

As above, I'm also on the verge of a obsolete product...

Annoying lesson to learn...

Would you mind sharing a Coconut Battery screenshot of your 2-power battery? Did you run Windows(Bootcamp) on your MBP?
I am using a 2-power battery with my MacBook5,1 and hope it will last longer than 12-month warranty period by Duracell Direct.

My Newertech battery is going strong, in fact, it's increasing in MAH as it breaks in. Now showing 100% 8471mah at 44 charge cycles. My last Ifixit battery was at 48% capacity at 34 charge cycles when it was removed and returned for the full refund. My ifixit batteries were NEW, meaning the date on coconut showsed they were like one month old, so factory fresh.

I recomend NOT gluing in your replacement battery until you confirm it won't need to be swapped out again soon...i put some folded up business cards over the batery before putting the lower cover back on, to compress and keep the battery from dropping once turned right side up.

Nope, never run bootcamp, in fact, as you'll see I never really had many load cycles on the battery. It's also manufactured very recently so it's not like I have an old unit. I purchased this mid October 2019 for reference, it cost me £74 GBP to the door.

Complete dud!

Apple have said they'll service it and I have an appointment booked for Tuesday. This is the UK for anyone else following.
