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 GoBook 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).
• Re-calibrate your battery when your battery performance degrades, or depending on usage.
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.
