BATTERY LIFE INFORMATION
The rechargeable battery should provide approximately 8 hours of wireless operation on a full charge.
However, all batteries age over time and gradually lose their ability to hold a charge.
•
The typical life span of a Li-Ion battery is two to three years, whether it is used or not. The life and
performance of a Li-Ion battery is not improved by cycling (discharging and recharging).
•
Always charge the battery whenever the low battery warning appears on your display screen.

The tablet draws current from the battery whenever the Wacom wireless module is on. To reduce power
drain, the tablet will enter sleep mode whenever the battery level is very low. The battery must be
recharged.
A small amount of current is drawn even in sleep mode, and will slowly discharge the battery. It is a
good idea to charge the battery and turn the wireless module off before leaving the tablet unused for a
number of days.
•
Once the battery voltage has fallen below a minimum safety level, an internal protection circuit within
the battery prevents any charging.
If a battery with a low charge remains in the tablet for an extended period of time, the small trickle of
current used by the tablet may discharge the battery so far that the internal protection circuit is
activated. If this occurs, you can no longer charge the battery. When leaving the tablet unused for an
extended period of time, preserve the battery by removing it from the tablet.
You cannot recharge a Li-Ion battery that has been over-discharged.
•
For extended battery storage (a month or longer), keeping the battery in a partially (not fully) charged
state, along with cool storage, can slow the aging process. The recommended charge level is
approximately 40% for optimum battery recharge when placed back into service. If storing both tablet
and battery, you do not need to remove the battery. However, it is always good practice to remove the
battery when storing the tablet.
Note that you may not be able to recharge the battery after 6 continuous months of non-use.
You will need to purchase a new battery when it is no longer capable of holding an adequate charge or can
no longer be charged. See
