OSTENT Real 1400mAh 3.6V Lithium Ion Li-ion Polymer Rechargeable Battery Pack Replacement Upgraded Version for Sony PSP 2000/3000 PSP-S280 Console Video Games

Amazing battery probably the best one especially out of the ones that I’ve used. Charges in about 45-an hour, seen other reviews saying there’s last about 3 hours, well not the case with mine it last about 5-7 hours just pure playing on an off would last me all day!! Great fit doesn’t fall out like other ones I’ve used great value for the money would 100/10 recommend!! (Modded psp 3000)

It’s a really well made battery, some cases better than the original Sony battery and just LOOKS better in general. Looks like an actual premium product and not a friggin bomb. Looks pretty decent if you have a clear PSP shell and the price is good. The battery life on this is also really great, getting over 6 hours which is around the same time as the official Sony batteries back then so it’s a really good replacement.

Best PSP slim battery on the market, very high quality and I've been very happy with the battery life. No complaints!

It looks amazing and it performs better than the original one for not a lot of money. A definite buy if you're looking for a replacement.

Good battery life

Pretty decent battery, charges quick and holds for a 3-4 hours of play for me

This installs easily, charges quickly, and holds the charge for a long time, just like the branded batteries that Sony doesn't sell anymore. No tools are necessary. All you have to to is open the back of your PSP, take out the old battery, and put this into its place. It charges in a few hours, and it's ready to go!

Works way better than any other aftermarket battery! Came to buy this after watching Total Kommando’s video on youtube about the psp’s battery testing
