Batterygeek 9V~12V, 60WH Ultra High Capacity Universal DVD Battery/ Charger 9-12-60
Just took to Europe
I love this battery. I just came back from Europe and took this battery along. My 8 inch Polaroid DVD player's stock battery only lasts at most 2 hours and 20 minutes. This battery lasted much longer than that. I didn't even fully drain the battery (I didn't recharge it either!). I got a good 7-8 hours off this battery with time to spare. Definitely worth the extra money. The battery is small enough to carry in a travel case and is easy to hook up. It also comes with detailed instructions. I received great customer service as well. A great buy!
