I have tried two of these batteries in two PSP Slim and Lites over a period of a more than a week and found that it only gave me a capacity of about 400mAh, that is it performed at about a third of what my original 1200mAh battery performed at. I also did some research on the internet and found numerous web sites that show similar results.

A good substitute for the original battery, a bit more capacity for the same battery size. I had expected this to be bigger than the standard battery, but it's not. Does the business.

the battery was definitely worth it, it works really well and is very reliable. the delivery was very quick and arrives two days after i ordered it, how cool is that. the crew at mighty ape are amazing and you should definitely do buisness with them. how cool is that. choice g
