My HTC Touch Cruise is fully dead, and I'm not sure if its the phone or the battery. The battery has 4 contacts, and tests a normal 3.8v across the out 2 contacts labeled + and -. I know LiIon batts have some sort of protection circuitry in them, to prevent over-charge and under discharge, so I'm hoping its only the battery which is fried.
Does anyone know what the other 2 contacts are for? Ie, maybe they tell the phone info about the batt or something. How would you test a batt like this?
Or does anyone know anywhere in Auck who sells HTC stuff? Maybe I could test it with another batt.
Thanks for any info!
