My sisters broken DVD player has a 7.4v, 4000 mAh Battery. Is it possible to use this?

Provided that you have a proper Lithium charger, than yes, you can use it. On my recent portable I used a bunch of cell phone batteries and re-wired them into a decent pack.

You find what pin(s) are negitive and what are positive. From there Ben used to my memory pins from Radioshack (with the Sony Info-Lithium). Be sure to glue them in place with lots of hot glue so they dont move, or if your sure their set right use epoxy.

Ok, i killed that battery, no big loss, ill still use the 9volts for lunch at school. But for longer expeditions, what is a good Li-ion to use?

Are you sure the battery's killed? As for other Li-ion's, www.sony.com has many varieties of Li-ion batteries. Some of them are expensive, though.

Its probably not killed, all the wiring from the old way is torn up. I could probably rewire it all if I get a soldering iron... Cant use the old charging unit though.

Note: Be carefull when using a screwdriver to pry something open that has no screw holes. It slipped and sliced my hand pretty bad.
