About Your Battery and System Tester
The battery tester is designed to test only 12 Volt batteries and systems. The
tester is compatible with a wide range of battery types, including Conventional,
Maintenance Free, AGM, Gel Cell, Marine and Deep Cycle batteries. The tester can
test these types of batteries against several battery capacity rating systems. Below
is a chart of the operating range of the tester, based on the applicable capacity
rating systems:

The tester has a recommended operating ambient temperature range of 32˚ F to
122˚ F.
Preparing Battery to Be Tested
1. Be sure area around battery is well ventilated while battery is being tested.
2. Clean battery terminals. Wire brush them if necessary. Be careful to keep
corrosion from coming in contact with eyes.
3. Inspect the battery for cracked or broken case or cover. If the battery is
damaged, do not use tester.
4. If the battery is not a sealed Maintenance Free battery, add distilled water in
each cell until battery acid reaches level specified by the manufacturer. This
helps purge excessive gas from cells. Be careful not to overfill.
5. Confirm that all vehicle accessories are turned OFF to ensure you do not cause
any arcing and that the tested battery has a nominal voltage of 12 Volts.
6. If it is necessary to remove battery from vehicle to test, always remove ground
terminal from battery first.
