To prevent battery explosion that could result in severe personal injury or death, extreme care
must be used with aerosol containers of battery terminal protectant. Insulate the metal container
to prevent the metal can from contacting battery terminals which could result in an explosion.
Use care to connect the battery wires as shown.
Tighten the battery post hardware to 90 - 100 in. lbs. (6 -8 Nm)
torque . Do not over-torque the terminal stud nut, this will cause a
“mushroom” effect on the battery post which will prevent the termi-
nal nut from being properly tightened.Protect the battery terminals
and battery wire terminals with a commercially available coating.
Protect the battery terminals and battery wire terminals with a com-
mercially available coating.
Battery Charging
The battery charger is designed to fully charge the battery set. If
the batteries are severely deep cycled, some automatic battery
chargers contain an electronic module that may not activate and
the battery charger will not function. Automatic chargers will deter-
mine the correct duration of charge to the battery set and will shut
off when the battery set is fully charged. Always refer to the instruc-
tions of the specific charger used.
Before charging, the following should be observed:
Do not overfill batteries. The charging cycle will expel electrolyte and result in component damage.
• The electrolyte level in all cells must be at the recommended level and cover the plates.
• The charging must take place in an area that is well ventilated and capable of removing the hydrogen gas that
is generated by the charging process. A minimum of five air exchanges per hour is recommended.
• The charging connector components must be in good condition and free from dirt or debris.
• The charger connector must be fully inserted into the vehicle receptacle.
• The charger connector/cord set is protected from damage and is located in an area to prevent injury that may
result from personnel running over or tripping over the cord set.
• The charger is automatically turned off during the connect/disconnect cycle and therefore no electrical arc is
generated at the DC plug/receptacle contacts.
AC Voltage
Battery charger output is directly related to the input voltage. If multiple vehicles are receiving an incomplete charge
in a normally adequate time period, low AC voltage could be the cause and the power company should be consulted.
Troubleshooting
In general, troubleshooting will be done for two distinct reasons. First, a battery that performs poorly and is outside of
the manufacturers specification should be identified in order to replace it under the terms of the manufacturer’s war-
