I've been using my Opus for about 3 years and I think the battery is finally dead. Doing a reset through the back doesn't work, and plugging in the Opus to my computer doesn't even turn on the light. Tried keeping it plugged for a couple of hours anyway and still reset doesn't work.
I started looking into getting a new battery. The one of the Bookeen site is for $30 and I'd rather pay for something cheaper. I found this one:

But it mentions that the battery require special charging and not to attempt to charge it with anything but a specialized Lithium Polymer charger.
Don't know much about ereader batteries and this sounds like I need to buy a separate charger? Does anyone have any recommendations on sites to buy the battery from and which charger I should get?
