Battery Maintenance and Storage
Maintaining Batteries
Follow these guidelines to maintain performance of Lithium-Ion (Li-on) batteries.
Avoid exposing batteries to extremely hot or cold temperatures for long periods. To prevent
possible damage to the battery, the Duo-Touch 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 every three months or when your battery performance degrades.
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, battery calibration may increase its capacity.
