higher or lower working environment can decrease the battery life span
The point that removing the battery when the UMD connects to adapter can increase the
life span of battery is not exactly right. Please keep the battery in the device when it runs
under adapter power because it will not make the battery overcharge. The charge
controlling and circuit protecting technology are adopted by UMD, once the battery is
full,charging will stop.
