When I was going through my battery research and tribulations for the bad ifixit battery. Someone posted a link to an eBay battery that was OEM and it was pretty cheap, like $30 bucks. It had the correct part or serial number on the listing. He ordered one and I figured it couldn't hurt to try it even though my nupower was on the way. When he installed his, it read as a manufacture date of March-2015 but did have zero cycles on it. Makes sense as they don't make these batteries anymore. I didn't want to put a battery that was sitting on a shelf for three years in my machine over the nupower which was a few months old from manufacture date.
After I installed High Sierra, my machine was crawling. I had not done any upgrades to this point. It was actually my college son's hand me down when he begged me for a new MBP because this one was slow and couldn't hold a charge. It was and is my first Mac. I had 4GB in it and upgraded to 16GB. I am sure it would have been fine with 8GB but it was short money. It then handled High Sierra fine, but when I bought the 16GB from Crucial, they spammed me with SSD upgrades. So I got one about a month after the RAM and WOW, what an upgrade. It became almost instant on and apps launched in half seconds. I subsequently replaced the Crucial 1333mhz RAM with overclocked 2133mhz RAM. It doubled in memory speed according to benchmarks.
I've done the RAM and SSD, and at a push, the battery looks straight forward enough and is essential too. As for the mhz.... not a clue.
I wonder if it would have just been enough to see the 16GB RAM with the HDD. Too late now, but would have been interesting. It's not bad, it's good enough, although when Snow Leopard was in, it was like lightning. And it's not quite that good with subsequent El Cap/Sierra/High Sierra. I get a lot of lag on Chrome, and sometimes Mail is painful. But for the age of it, that's good enough at the moment. And as discussed, the options on new don't excite me as much as they should, other than aesthetically, because there is more on what I have, options wise, and USB wise. I've lost the use of Photoshop with HS, and Word 11 is showing different fonts and acting weird, despite compatibility being ticked on roaring apps.
One thing I didn't do, and don't know if it was a mistake, was not to set up TRIM,
In this instance the system reset’s plus the calibration have worked very well for me. I do believe that the calibration is most definitely required and that, plus the SMC reset seem’s to make very good sense, especially as the SMC looks after things like power and charging.
I started looking for my battery replacement almost a year prior to finally buying and the one thing I found was a complete lack of good information and reviews on third party batteries.
Of course, you do not get much help on this board when people just chime in with “buy an Apple battery”. This would of course be the preferred action we would all like to take if we were not cut off by Apple themselves.
Establishing a section on this forum dedicated to the discussion of batteries would be a good step in the right direction, there is no consistent information available anywhere.
……….and I have been dying to say this, “you should ride in the front Mr. Franks”.
Your 'buy Apple' comment made me laugh, but yeh, if we could get an OEM new, most of us probably definitely would. Safer bet. And chances of it being like the original fitted are high. If most of these replacements don't come close to original, what is it they're doing at Apple, that they can't do 3rd party. The people that made them for Apple, must be out there somewhere?
Is it because
it's a lot 'smooder' ride in the front? Top film, Did you ask me this question before? One person mentioned that to me before on here a few years back. I told them that I used to see him and met him several times for dinner back in the 90s. He died last year, I think it was.
