The scanner battery and the tablet removable batteries are Lithium-ion type. When the battery can no
longer hold the required charge or is damaged, it should be disposed of properly according to local reg-
ulations for this type of battery. You can also return the battery to AS&E if you are unsure of your local
regulations for Lithium-ion battery disposal.

Extending Battery Life
Battery charge can be best conserved by keeping the battery out of temperature extremes and by turn-
ing-off the system when not in use (not using Sleep mode), and removing batteries when they will not
be used for a long period. Rechargeable batteries have a limit to the quantity of times they can be
recharged. This is a result of a small residual deterioration.
The scanner battery is a special smart battery. It contains an internal serial number that can be read out
to the tablet. It is rated to be recharged 300 times before the recharge capacity drops to 80% of the
new-battery level. To help predict use life, the battery logic tracks each recharging event, and the
cumulative total of recharges can be read out to the tablet. If the battery is connected to the charger
while it still retains more than 90% of full charge, the charger will not start a charging cycle.
When the scanner unit rechargeable battery is depleted, it is designed to retain sufficient residual
charge to continue to power the control circuits of the device and allow recharging. Immediately
recharge a fully depleted battery:
• Do not store a depleted battery before recharging to at least 50% of full charge (100% is ideal for
maximum storage life).
• Do not connect a depleted battery to an unpowered charger.
• Do not attempt to continue to use a depleted battery.
The tablet reduces the full charge level of the main battery pack gradually over time, in order to extend
battery life. Every time the battery is recharged, it reduces the remaining use life, so the manufacturer
recommends not recharging the battery until it reaches 10% remaining. This level is indicated by the
battery indicator on the touchscreen frame
displaying red. If the battery is connected to the
charger while it still retains more than 95% of full charge, the charger will not start a charging cycle.

Storing and Shipping Batteries
To avoid temperature build-up during recharging the tablet main battery pack, consider
turning off the tablet during recharging.
Tablets can reduce battery consumption by lowering screen brightness. See
