A cr123 3volt battery. They can be pricey if purchased one at a time but reasonable if purchased in bulk.

It uses a CR2032 nickel battery. The battery comes pre-installed. I've had mine for 7 months now, and the battery shows no signs of wearing down.

I have no idea. Sorry. All I know is that I've been using it for half a year and it works like a charm. Still gives me more extra hours than a regular battery.

No.. it's a non standard battery. See the answers under the replacement battery unit for clarification.

The battery is CR2032 3V Lithium. When you open the unit the battery should have the number stamped on it.

It's a Lithium ion Battery No. CGR-H712 (7.2V 4200mAh Wh Li-ion Battery, Series 11) which is normally attached to the unit if bought brand new. If not, you can call Panasonic, the manufacturer if you have any questions at USA and Puerto Rico: 1-800-211-PANA(7262) or Canada at: 1-800-561-5505. Just provide them with the Model No. DVD-L-S86. Hope this helps.

I'm not sure, couldn't really use the unit much because the battery wouldn't hold for more than a few min after a full charge, but otherwise it's not a bad of a unit in terms of basic function, good luck to u

I have no idea since it was a gift for someone. You can probably take it to Radio Shack and they can tell you what type of battery it needs. Hope that helps.

I don't know, the one I had purchased was OLD, and the original battery had been installed, which leaked and rendered the unit unusable.

The battery is built in. Below the unit has the charging cord and my unit has lasted days on low setting.

I've opened up the unit and I couldn't find the same battery size to buy. I believe the one that I did find was almost the price of the unit.
