Leave the display tilted open and allow unrestricted airflow while the
battery is charging. This allows excess heat to escape from the battery
compartment and helps prevent the battery from overheating.
The battery starts fast charging automatically, and the external power
indicator light blinks while the battery is charging. At moderate
temperatures, around 70 degrees Fahrenheit, the battery will complete
charging in 3 to 4 hours. Under extremely cold or hot temperatures,
however, the battery can take up to 16 hours to fully charge.
Battery Storage and Care
Follow these guidelines to maintain performance of 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 batteries nightly where the temperature will remain
around 20°C (68°F).
•
Store the batteries within the recommended temperature range:
10°C to 30°C (50°F to 86°F).
•
After storage, or periods during which the battery has not been used,
deep cycling it 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.
