Hi all,

I need a replacement battery for an A1297 2011 17" MBP Unibody, which I currently believe to have a faulty 3rd party battery (A1383 spec) that never worked.

However it looks like there are two versions that are being sold:

- A1309 2009/2011 Battery-A1297 7.4V 95WH (£70)
- A1383 2011/2011 Battery-A1297 10.95V 95WH (£75)

They both are apparently suitable for an A1297 MBP, with a £5 difference for a genuine/new Apple replacement on eBay.

Can anyone suggest which is best for my old laptop? I've tried asking the seller on eBay, but no response (hey, it's the holidays).

Many thanks,

Ed

Have you been able to sort out the battery? I have an early 2011 Macbook Pro 17in with a completely dead battery and trying to get my head around the best option to go for to replace it.

I'm afraid not - was waiting for a reply to this thread! :)
That's a shame, from my brief research it looks like 10.95V is the correct one - ifixit list the lower voltage for 2009-2010 and the higher voltage for the 2011 model:


Where have you been looking to buy from? A glance around the forum recommends the Newertech batteries which I can only find for sale from sites I'm not familiar with for around the £100 mark. My initial thought was ifixit who have one for £92 but the reviews on their site aren't that good, it doesn't look like Apple will cover a machine of this age for £129 unfortunately.

Here's the best battery for your 2011 17" MacBook Pro. Not cheap, but good quality and warranted.

Yes, I'm a bit wary of it too. Coconut battery says that it was made in 2020 so I don't really understand. Says it's 97% of full capacity.

Maybe I've been had, but it seems to be working. At least, the battery charged, the machine booted up normally with normal performance (previously it was acting as if no battery was in, so the performance was 100x slower than normal), and it does have Apple markings on it.

I need to do a bit more testing to be 100% sure, and I'll report back soon (no, really).

My guess is that 9 out of 10 "genuine/new Apple replacement" batteries being sold on ebay (for not much more than 3rd party batteries) are actually fakes and counterfeits...

You might have to "re-program" your battery: Charge to 100% + 2 hours, discharge to black screen, recharge to 100%
