Batteries; Battery Care - Hummer H3 2015 Owner's Manual

Batteries

Your vehicle is operated as a 48-volt unit with six (6) 8-Volt batteries. The batteries
are Trojan® T-875 deep-cycle batteries, specially designed and produced for use
in an electric vehicle. If the batteries need to be replaced at any time for any reason,
do not use automotive batteries. New batteries usually will not deliver their full
capabilities until they have been discharged and recharged 15 to 30 times. To
obtain maximum service life on your batteries, be sure to fully charge them prior to
using the vehicle for the first time and maintain proper fluid levels in all batteries.

Battery Care

To keep the batteries in top working condition, this maintenance program should be
followed on a regular basis:
1. The batteries should always be kept clean and corrosion free. The tops
and terminals should be cleaned with a solution of one cup of baking
soda per gallon of water. Before rinsing the batteries make sure the caps
to the batteries are tight so that the cleaning solution does not enter the
battery.
Please be sure to dispose of any waste water properly.
2. The fluid level in the batteries should be checked on a weekly basis.
If fluid needs to be added, it should only be done after the batteries have
been charged unless the top of the plates are visible prior to charging.
Then, you should add just enough water to cover the tops of the plates,
charge the batteries and finally check the water level again.
3. After using your golf cart for any period of time, the batteries should be
charged.
If battery wire terminals are damaged or corroded, they should be
replaced or cleaned as necessary.
Failure to do so may cause them to overheat during operation.
WARNING! – HIGH VOLTAGE
The battery pack is at a high voltage.
