Insten Rechargeable Battery Compatible with Sony PSP 1000 1001 High Capacity 1800mAh Battery Pack US (Not Compatible with PSP-2000 or 3000 or PSP Slim)

Works great in older PSP 1000. I ordered two batteries from different vendors/suppliers here on Amazon. This is the only battery that has not intermittently powered off the PSP despite having over half a charge. I have purchased batteries for other devices from eForCity and they have worked so far. eForCity is usually my first choice when I am looking for compatible batteries for our older devices.

This battery is miles ahead of the stock battery (1200mah) but not as good as Sony's 2200 MhA battery.if you have to replace the battery in your psp and whant a battery get this one and sony's 2200 one the external charger and you can run almost none stop .

I feel great about the value and quality of the products I received. I am most happy about the fact they were brand new and work perfectly. I will be returning to get more products from this website.

Got this for my fiancée because his original PSP 1001 battery died. It fits fine enough (he with the knowledge of the PSP had to fit the back on since I couldn't seem to do it) and he says it's about the same as the original in terms of how long it lasts. Occasionally it does shut itself off though for no reason and you have to wait a bit before turning it on again...other than that, no problems.

I bought this since the reviews for this battery were favorable at the time and my old sony psp battery had died to the point where it couldn't hold a charge and the price was not too bad. Too good to be true? Sadly this is the case, my new battery that I just ordered isnt much better than my dead battery. Instead of holding a charge for a minute like my previous battery which is dead, this battery died after 20 minutes of me playing a ps1 game. Definitely buy another battery unless you want to be back on amazon browsing for psp batteries again.

bought this to replace my aging old one that didnt hold a charge too well. thought i was gonna have a bad time using it since im running custom firmware on my psp, but to my surprise it worked just fine with zero problems!!

Cheap battery that does the job. I've gone through a couple of these, but can't beat for the price. Make sure you unplug your PSP when charged. Keeping it plugged in after charged will drain battery life.

Gets the job done. On my PSP3000 it's a bit too fat, but it still works & charges fine. I'm just worried it may pop out because my battery cover doesn't fit over this.
