There is a thermistor in Battery to prevent from overheat. Thermal detection range is 5˚~35˚ C.
If terminal voltage of CHGOUT+ is 2.3V, the charge/ recharge to CELL will be completed after about
6 hours.
Warrantee charge/ recharge times are 300 times. But charge/ recharge times can be performed more
than 300 times actually.
Using Compact Flash Memory Card frequently, this battery life will be shortened.
It is recommended that the unit is driven by AC Adapter when using this card.
