The battery in my a1181 is completely dead. Like… The system doesn’t even see that there’s a battery even in there. It works when it’s plugged in, but it’s really sluggish and a bit flaky on startup.

I want to replace it and breathe some new life into this MacBook, but I don’t know where to find decent replacement batteries. I’ve seen some on Amazon, but I’m a bit wary of those.
