I bought from this guy back before he changed the items a bit (I got a different charge cable and no case). The batteries work well. The charger is useful to charge a battery outside the N800 (if you have 2 chargers, charge two at once). I carry the 2 spare batteries in my case and very rarely (as in, never) run out of batteries now. Here's the link (in Hong Kong)

(I should mention that I got TWO batteries, charger, USB-N800 charge cable (Extendable), AND a nice strap for an ID card, all for $14, SHIPPED, from Hong Kong. Hard to beat that.
