Battery Maintenance and Storage
Maintaining Batteries
Follow these guidelines to maintain performance of Nickel Metal
Hydride (NiMH) batteries.
•
Avoid exposing batteries to extremely hot or cold temperatures for
long periods. To prevent possible damage to the battery, the mobile
computer does not allow the battery to charge if the internal
temperature of the battery gets too low (< 5°C or < 41°F) or too
high (> 50°C or > 122°F).
•
Charge the battery nightly where the temperature will remain around
20°C (68°F).
Storing Batteries
•
Store the battery within the recommended temperature range: 10°C
to 30°C (50°F to 86°F).
•
Unused or stored batteries can lose power over time. When you
install a battery that has not been used for awhile, connect external
power to the computer and charge the battery.
•
After storage, deep cycling the battery up to four times in succession
may increase its capacity. You may want to do this over consecutive
weekends since each deep cycle process can take up to 40 hours.
After this initial conditioning, maintain battery capacity by deep
cycling at the recommended frequency.
