If you are like me and like to use this PDA’s features to its fullest, i.e. as an audio & video player, GPS, WiFi, HSDPA, Bluetooth, A2DP, etc. you may find that a fully-charged battery will not get you through the day. Finding a replacement battery may be a good idea, and the Japod battery turns out to be a worthy replacement for the stock TyTN II battery.
