OPERATING INSTRUCTIONS
Testing the Battery
CAUTION! Undercharged lead-acid batteries will freeze during cold weather.
NEVER TEST OR CHARGE A FROZEN BATTERY.
1. To help ensure a good connection, clean battery terminals with a solution of
baking soda and water, and wipe the battery terminals with a cloth to remove
any dirt and grease.
2. Connect the red (positive) Cable Clamp (A) to the positive terminal (+) on the 6
or 12 V lead-acid battery. (See photo above.)
3. Connect the black (negative) Cable Clamp (B) to the negative terminal (–) on
the battery. Turn clamps slightly to ensure a good connection.
4. With the clamps connected, the tester’s gauge will show the battery’s current
charge. If it is less than 12 V, disconnect the battery and recharge before testing.
If recharging will not bring the reading above 12 V the battery is defective. If it
shows no reading, verify that the tester is connected properly. If the tester is
connected properly, the battery is defective.
5. Press (and hold) the Toggle Switch (C) for at least 5 seconds to simulate an
actual load on the battery.
