I've never understood why there isn't a fairly simple company out there manufacturing quality lithium ion cells for older tech. For instance, I have an original Sony PSP. There's nothing wrong with it. Except for the fact that it is impossible to find a battery for it and the original ones wore out long ago. I faced the same thing with my Neato Botvac when it's NiCad battery died, although I was lucky enough to be able to find an adapted LiIon battery to replace it (which also extended its operating time, enabled it to charge faster, etc. Nice upgrade!). My mom is having a very difficult time finding a new battery for her first-gen Dell XPS 13. Every time I go online to shop for a battery, it feels like a fight with 99% of the products on offer being dodgy. It's almost as bad as the bedding industry which is perplexingly corrupt and soaked neck-deep in black PR.
