So I removed my battery, with minimal force using a spudger and the smallest screwdriver from my IFixit kit. (Thank you, IFixit.) But the new battery, which I just bought through newegg.com and everywhere else says it is “rechargeable,” which makes little to no sense since it stopped working after a year or so … Anyway, I heeded dakeldsen’s advice above and bought the same battery- I don’t need fire issues. Really who does? Other than this, I have loved my Logitech keyboard … It’s worked beautifully for a little over a year.
