7.4 Battery Charging
WARNING!
For detailed information on charging your powerbase batteries, please be certain to read and
follow the instructions provided by the powerbase manufacturer & the battery charger manufacturer
.
•
Do Not
use the
charge level indicator

The joystick display indicates
surface voltage
surface voltage only, and may not be the true charge.
(This can be likened
to charging a cell phone; if placed on its charger for a brief time, a cell phone display will often indicate that
the batteries are fully charged, however the cell phone quickly goes dead once it is used).
• Heavily depleted batteries require more time to recharge. Insufficient charge time may result in the
supply of

to recharge rehab-style power products.
• Batteries that require more frequent charging or take longer to charge than normal, may need to be
replaced.

7.0 GENERAL MAINTENANCE & SAFETY
7.5.1 Battery Case Draw Test
1. Inspect battery for signs of corrosion, moisture and/or dirt
that could lead to unnecessary discharge of the battery.
2. Test with Voltmeter by placing one lead on the
Positive
Positive
(+) RED
(+) RED battery terminal
3. Drag the other lead across the battery case (in different
locations).
4. Voltmeter should read
0 (zero)
if there is no discharge from
the battery.
