Charging a Battery Pack
A battery pack can be recharged wherever external power is available.
Charging may be delayed if a battery pack is new, has not been used for 2 weeks or more, or is much warmer or

To increase the accuracy of all battery charge displays:
Allow a battery pack to discharge to the low-battery level through normal use before charging it.
When you charge a battery pack, charge it fully.
