It's a Battery that is originaly produced for Nokia-Handys. It has 1600mAh, and is as big as the smal Sharp-battery. The Battery has the elektroic part for overhead-, short-circuit-, superchargin- protection.
For more safety, I solder an NTC (10k) into the conduction.
In this way, the zaurus is able to control the temperature of the battery.
And... if there will be any problems (like it isn't getting charged,... I will send a new one.
But I don't give any warrenty!
