2.5.1 - Rechargeable Batteries
Though we recommend standard alkaline AA batteries, rechargeable batteries are
offered. This option includes 2 AA NiMH 2700 mA rechargeable batteries. The
system is supplied with a external wall charger.
The batteries should be charged:
1. Prior to using the unit for the first time.
2. Before use, if more than two months have passed since the last charge.
3. When LO:BAT (low battery) is displayed on the screen.
A full charge will take 10-14 hours.
Store bought rechargeable batteries may be used. Choose NiMH AA size 1.2V
rechargeable batteries (minimum 1800mAH or higher) and a standard charger.
Due to the difference in battery voltage, rechargeable batteries will display a biased
energy level. For example, fully charged NiMH batteries will only show an energy
level of 80% rather than 100% and will normally show a value about 20% less than
the actual level.
WARNING
It is dangerous to charge disposable batteries and may result in the batteries
exploding. If you are using disposable batteries in a system sold with
rechargeable ones, please remove the charger from the system's carrying case
or place of storage in order to prevent potential accidents.
