9.4. Battery
Charging the battery involves leaving the unit connected to an AC power source while powered
on, preferably overnight.
The battery should be charged before and after every election. The battery should be charged
again once every six to eight months to ensure that it would hold a sufficient charge. In the case
that the battery is no longer sufficiently charged, it should be replaced. Note that the low battery
symbol (‡) that may appear in the lower left-hand corner of the LCD, applies only to the memory
card battery.
Ensure that all power and extension cords are properly connected, and that AC power is constant
and uninterrupted, as a disruption in power will cause batteries to drain rather than charge.
This procedure tests the battery’s ability to hold a charge—
the battery should always be fully
charged before testing
.

Recommended Battery Test
The battery’s ability to hold a charge may be tested by printing three Printer Test reports in
Diagnostics Mode without AC power. A weak battery will be indicated if the printer runs but does
not print anything. A weak battery may also be indicated by the continuous display of the battery
low message.
1. Enter Diagnostics Mode by powering the AccuVote-OS on while pressing the YES and NO
buttons.
2. Remove the AccuVote-OS power cord.
