1 Getting started
Fully charging the standard 3100mAh battery from empty takes approximately four hours
when connected to main power. The extended 4800mAh battery will take longer to charge.

Avoid keeping the battery at full charge at high temperatures.
NOTE – The life of the battery can be significantly shortened if power is constantly supplied
