CHARGING THE BATTERIES/CAPACITY GAUGE OPERATION

Overview
Note:
Battery charging is as easy as driving the AMX−4+ to a correctly rated wall outlet and
plugging the unit in. Ratings are as follows:

The time required to fully recharge the AMX−4+ batteries will vary according to bat-
tery charge level as indicated on the battery status display.
During recharge the AMX−4+ capacity gauge increases as the unit is charged. To re-
charge from 10% to 100% typically requires 4−5 hours.
Occasionally the AMX−4+ automatically performs an extended charge to make sure
that all portions of the battery's internal plates get fully charged. This extended charge
occurs every twentieth time the battery is charged.
To recharge from 10% to 100% during an extended charge typically requires 10 hours.
The AMX−4+ will continue to attempt extended charges until at least half of the ex-
tended charge time is complete.
The extended charge will be transparent to the operator. The only indica-
tion that it is in progress is the longer charge time.
Although portable application will vary site to site, under most operating conditions, a
fully charged AMX−4+ is designed to supply enough charge for a typical 8−hour
shift.
The AMX−4+ capacity gauge visually displays the remaining capacity using a 48 seg-
ment bargraph display.
