How long can I store a new lithium battery before installing it?
I'm in the process of buying a new battery for my Dell laptop and I need to do it while I'm in the US, because I can't find reputable brand ones in Europe, namely iFixit, but also the oem from Dell. However, I don't want to install it right away, because I can probably still go one year or so with the one I have in the laptop right now. How long can I store a new battery before installing it?
