Polaris battery upgrade

[rhov23]

I didn't find the polaris battery on batteryupgrade.com as i want to have a spare battery for gps tracking that is at least 3000mah. Is the battery the same as on any other htc devices?

The biggest battery i have seen so far is only a poor 1500mah which is no good for a days worth of gps tracking (Memory Map) so am looking to buy a external battery at 5400mah if no larger internal battery is available.
