I just bought 2 more Nokia OEM BP-5l from this pricegrabber storefront. The first battery I bought from them runs longer than the OEM battery delivered in the box with my N800 when it was new. I was concerned when I first got it as the battery terminals had contact scratches on them...used?....but the battery worked fine for $15. Original Cellular has over 4,400 comments rating over 4 stars. They shipped me two more this week in less than a day. We'll see.

As to chargers, I bought several Chinese desktop chargers for BP-5l from www.elcell.co.uk that were so cheap I ordered 4 of them. They use the Nokia cords, both AC or DC, and charge as fast as the tablet, changing their LED indicator when the charge is complete to a different color. All worked great. The ones in my cars run 24/7 to a hot cig socket so they charge the dead cell when I'm out of the car or in. Work great for a couple of bucks, shipped from England. Shield your eyes if you go to the UK site so you aren't blinded by the new N96 staring you in the face making you drool.
