Need help w/ salvaging psp battery

[Amgine]

Okay so i have one of these Amazon.com: PSP DOUBLE LIFE 3600MAH BATTERY TWICE 1800MAH LIFE: Video Games laying around and i'd really like to use it for my first mod. Trouble is i've never done anything like this before and i can't figure out how to get at the terminals to make a circuit. Any help you guys can provide for this would be great.

I think you may have some problems charging the batt later on but i will let the masters speak

I would be dubious about using that particular battery. It is a Li-Ion and can be charged with a regular 3.7V Li-Ion charger, but you shouldn't waste your time on something that "might" work with questionable safety. This is something you'll be putting up to your face all the time. You don't want to do anything sketchy. These batteries can do ugly things if something screwy happens.

I did a quick Google on that battery and I saw some claims that's its a cheap Chinese battery with greatly exaggerated capacity. Some even claimed it's a scam. I believe it. You have to be discerning with stuff from China. It wouldn't be the first time I've seen falsified specs on a product from over there. If the specs are falsified, it opens the possibility for grave safety issues.

You should pick up a LiPo batt if a flat cell is really what you want. That will work well for sure and will be safe with the required protection circuitry. You can find various vendors online for them. Here's one with protection built-in. However, they don't all come with protection so you need to add it if not included.
