TESTING
NOTE: A combination of the Load Test and Specific Gravity Test should
be used to accurately determine the condition of the batteries.
Load Test (6-volt batteries only)
NOTE: The batteries must be fully charged before performing this test.
1. Clean the batteries. Refer to
Cleaning the Batteries
section for information on cleaning
the batteries.
2. Load test each battery using a battery load test meter (available at most auto parts
distributors). Follow the instructions provided with the test meter.
• If any battery fails the load test, then it should be replaced.
NOTE: If the batteries are over one year old, it is recommended to replace
them as a set.
• If all batteries fail the test you should check the charging system before replacing the
batteries. Refer to Charger Troubleshooting section for information on checking the
charging system.
Explosive mixtures of Hydrogen gas are present within battery cells
at all times. Do not work with or charge battery in an area where
open flames (including gas furnace or water heater pilots), sparks,
cigarettes, or any other sources of combustion are present. Always
provide ample ventilation in rooms where batteries are being charged.
Failure to do so may result in severe bodily injury and/or property
damage.
Battery electrolyte is poisonous and dangerous. It contains sulfuric
acid. Avoid contact with skin eyes or clothing. Wear rubber gloves
and safety glasses while servicing batteries. DO NOT INGEST! This
may result in severe bodily injury.
A battery is a live electrical source. It cannot be disconnected or
neutralized. Do not drop any tool or conductive object onto the battery.
A conductive object that comes in contact with the battery terminals
will initiate a short circuit of the battery. This could cause the battery
to explode resulting in severe bodily injury and/or property damage.
