Keeping Batteries in Optimal Condition

Always operate the test tool on batteries until an
appears on the bottom line of the screen. This indicates
that the battery level is low and that the batteries need to
be recharged.
Frequent charging of the batteries when they are not
completely empty can reduce the operating time for the
test tool.
You can refresh the battery pack at any time. This battery
refresh cycle fully discharges and charges the battery pack.
A complete refresh cycle takes about 20 hours and should
be done at least four times a year.
Be sure not to disconnect the Power Adapter
during the complete refresh cycle. Doing so will
interrupt the refresh cycle.
