BATTERY LIFE INFORMATION
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.
You will need to purchase a new tablet battery when it is no longer capable of holding an adequate charge.
For information on ordering a replacement battery, see ordering parts and accessories
. Batteries can also
be purchased at various retail outlets.
• The life and performance of Li-Ion batteries is not improved by cycling (discharging and recharging) the
batteries.
• Cool storage and keeping the battery in a partially (not fully) charged state when not in use can slow the
aging process.
• Always charge your tablet battery whenever the low battery warning appears on your display screen, or
at the latest when the tablet battery status light begins to flash red. To reduce the power consumption
of an empty battery, the tablet will enter an auto shut-down state whenever the battery level is very low.
In this state the tablet will continue to draw a small amount of power. The power switch must be turned
off and the battery must be recharged.
• The tablet will draw current from the battery whenever the power switch is in the on position. A small
current is drawn even in auto sleep and tablet auto shut-down modes, and will slowly discharge the
battery. It is a good idea to charge the battery and move the tablet power switch to the off position
before leaving the tablet unused for a number of days.
• If the battery charge is low and the battery remains in the tablet for a long period of time (a week or
longer) with the power switch in the on position, the small trickle of current used by the tablet is likely to
discharge the battery so far that an internal protection circuit within the battery is activated. If this
occurs you will no longer be able to charge the battery. To preserve your battery, be sure to move the
tablet power switch to the off position before leaving the tablet unused for a week or longer.
• For extended storage (a month or longer), Wacom recommends that the battery be at least half full
before you move the power switch to the off position. You do not need to remove the battery because
the power switch disconnects the battery from the tablet circuit when in the off position.
• An internal protection circuit within the battery prevents any charging once the voltage has fallen below
a minimum safety level. Once a Li-Ion battery has been over-discharged it cannot be recharged.
