What is that inner 7.2V battery supposed to do in most laptops? I know there is always another battery that is supposed to store CMOS data and it's rated 3V/3.3V/3.6V so what is the purpose of that bigger one that is rated around 7V? This one is especially crappy because it tends to leak the most on old hardware. I'm especially baffled because everyone talks about the 3V CMOS battery and you can find a bunch of articles about it but NOBODY talks about the 7V one and I absolutely can't find any information about it
