I recently bought a new battery for my netbook. The netbook was made in 2010.
I'm guessing the replacement battery was probably manufactured around the same time. (I just can't picture any companies making new batteries for something like this a year or two past the date the system was released, but I could be wrong)
The battery was at 0% when I got it.
I don't know if I'm allowed to post the company I bought the battery from, or the brand of battery, so I won't for now.
I charged it up and let the battery drain to 60% over the course of several hours. It seems decent enough, I don't need crazy battery life, just something longer than 10 minutes, which is what my old OEM battery sadly was down to.
So with this new battery...how carefully do I need to keep an eye on it? What is the risk of bulging or fire? I'm less concerned about how well the battery might work, and more concerned with safety risk.
This is the first time I have bought a replacement battery for any hardware, and I simply don't know what the risks are.
