I purchased this battery as a spare for my Panasonic DVD-LS50 portable DVD player (ASIN B00021Z98A). The package says that it's for the DVD-LS50 and the LS55. I don't know anything about the LS55, but this battery is identical to the one that comes with the LS50 - same shape, color, and size, same model number, same labels. I had to mark mine in order to tell them apart.

The package says that this battery provides 2.5 - 4 hours of power, but it really is just 2.5 hours. I can't see how it's possible to stretch that to 4 hours, which is why I bought this spare. You won't be able to watch 2 regular movies with just one battery.

The battery can only be charged when it's inserted into the DVD player, so it's not possible to charge this battery while using the other one to watch a movie. According to the manual, recharge time is 4 hours for the LS50 and 7 hours for the LS55.

I bought this battery at the same time I bought my DVD player, so I didn't know what I was getting. If you're doing the same thing, then let me describe the battery. It's 7x1x1.5 inches in size. It's actually smaller than that, but the shape is too hard to describe. Suffice it to say that you'll have no problem carrying this battery with you.

I gave this battery 4 stars instead of 5 because I think it's too expensive. It costs the same as a universal battery, but the only advantage it has is that it's smaller.

Panasonic DVD Battery  Feb 20, 2009

I don't use my DVD player that often, but found out the hard way, you need to use it and recharge your battery once a month. Costly to not do that. This is the battery I needed for my Panasonic. It works great, just remember recharge your DVD player once a month.
