Odds of getting 2 dead batteries?

[flat6pilot]

I have a 2010 MBP 15 with the tired original battery.

Ordered an aftermarket replacement (PowerWoo) off amazon. Installed and computer/coconut battery would not recognize battery. Would not charge and only runs off the charger (shuts off immediately when disconnecting Magsafe). Coconut battery shows no data.

Figured it was a bad battery and ordered a OEM replacement off eBay. OEM replacement arrived and had the exact same issue. Coconut battery initially registered the new OEM battery as having a Sept 2019 build date, 0 cycles, 0% capacity, temp -273 degrees celsius. Restarted computer and the battery build date now went away in coconut. Did a SMC and PRAM reset with no change. Still will not run off the charger.

Reinstalled the original battery and everything works like normal again. Both replacement batteries were correct A1321 model numbers. Did I just get unlucky and have two batteries that were DOA or is there another issue at play?

The issue is just that there's a lot of money to be made in Apple batteries, and there are a lot of junk vendors out there. There's no battery you're buying that's an actual OEM battery for these computers.

Even if it looks identical to the original with the same "Designed by Apple in California" sticker?

Yes, Apple doesn't sell its batteries except to its service providers, and Apple counterfeits are rampant.

Appears you have the same Model designation as my mid 2009. Replaced the battery about 1/2 yr ago with a manufacture date of mid 2021. So your 2nd purchase appears quite old from the get go.

Coconut really gives crap all information in comparison to System information under the Power setting. Any decent manufacturer will display their name and serial number of the battery. Not sure what's going on with that weird temp and 0% capacity.

Had you not mentioned that the original battery charges and operates, I would have tipped that the power supply circuit has gone south. I've had two replaced already. This however is sounding a lot like dodgy batteries.

OP:

After two failures, I would not buy another battery from the same vendor that you bought from (that gave you bad ones).

I suggest that you bite the bullet, spend a little more, and get a battery from a place like Other World Computing and see how that works out...

thank you- it was two different venders but sub $40 batteries (amazon and ebay). Will go the OWC route.

That's another issue. You get what you pay for and $40 notebook batteries will be garbage.
