Eh, I opted for a new battery after all

I found the NewerTech NuPower 103 Wh battery for my early 2009 MBP for $95, and since it is clear I won't be replacing this machine anytime soon, I went and ahead and got one. The current battery is nearly dead, going from full charge to warnings almost as soon as I take it off the charger.

I hesitated to spend that much on a battery for such an old machine, but it still runs great and I still use it a lot, so I figured it was a worthwhile repair. It's really the last thing to do on this old Mac, as it already has 8GB of DDR3-RAM.

The question is calibration - do you need to be running MacOS to calibrate the battery or is that a firmware thing? If so, where can I get a copy of El Capitan to restore it with?

Does it have a network/internet restore function? I feel like 2009 was when the iMacs got it.

Dayum. I just replaced the battery on my 2014 MBP, and I thought that was borderline too old.

I wasn't going to, but we just had to replace a car, so the odds of me getting a new laptop are pretty slim at the moment. That, and it still works for what I use it for.

It fits, though. I still drive a 2004 Honda Accord as my commuter car, still use a Galaxy S7 Edge as my phone, etc. If it ain't broke, don't fix/replace it.

You can get an UPGRADE to OS X Yosemite 10.10 thru OS X Catalina 10.15 here--which includes OS X El Capitan 10.11--BUT each of these requires an installation of an earlier version of OS X (so Yosemite 10.10, Mavericks 10.9, Mountain Lion 10.8, Lion 10.7 or Snow Leopard 10.6). Personally I still have the installation CD for Snow Leopard for this purpose.

For completeness, go here for the OS X El Capitan 10.11.6 Combo Update to complete that El Cap installation.

It seems this old Mac just doesn't like NewerTech batteries. The replacement is doing the same thing - only worse. The original battery would generally let the machine boot, but the new battery is causing crapouts before the screen turns dark (Mojave).

I guess it's time to return it for a refund and either live with a 10m battery or find something that is closer to the original.

Where are you getting these batteries? OWC?

They own the NewerTech brand, so probably.

They used to be a super-awesome company, they still seem to be pretty innovative and their customer support is solid; but they can get bad batches of chinesium products just like anybody else these days.

Yeah, this was through OWC. I went with them largely because of their reputation and past experience. I've bought stuff for Macs from them in the past, and generally been pretty happy with the parts.

Hmmm ...

I've always had good luck with things from OWC. I haven't bought anything from them in a while, tho

I ordered something from them in 2019, and it was still good. Like you, I've had good experiences with them in the past.

So, it seems I may have been wrong about the OWC battery after all. My MBP has started acting up in general, and after a bit of diagnosis, it appears to have the C7771 problem - where a failing tantalum capacitor drags down one of the power rails.

Fortunately, I have access to a hot air machine and soldering station, so I can fix it for the cost of a new capacitor. I do feel like a schmuck for not figuring it out BEFORE I returned the new battery for a refund.

Dude I wish I was good with a soldering iron. I was ripped off buying beats by headphones that turned out to have a dead battery.

I am learning.

So far I've only set one shirt on fire and added scorch marks to some furniture, but I almost got an LCD screen to work, and my CNC machine has a perfect custom wiring harness.

My dad makes it look so easy. He replaced a capacitor on the internet switch ribby gave me. Good as new.

I lost a perfectly good G5 iMac to bad capacitors.
Turns out Apple knew about the problem and offered to fix it, but only for a limited time. Of course, I didn't find out about that until the time had passed.
What really wasted me off was that the iMac was a BTO straight off Apple's website. They had the serial number and manufacture date and my email address, but they did not contact me. They should have notified everyone that had a machine that was compromised by the bad batch of capacitors. I was wasted at them for years over that.

The limited time is blatherskite. It should be a lifetime replacement. Or exchange the whole unit for one without the bad parts.
