Test Preparation

Inspecting the Battery

Before starting the test visually inspect the battery for:
Cracked, buckled, or leaking case. If you see any of these
•
defects, replace the battery.
Corroded, loose, or damaged cables and connections. Re-
•
pair or replace them as needed.
Corrosion on the battery terminals, and dirt or acid on the
•
case top. Clean the case and terminals using a wire brush
and a mixture of water and baking soda.
Low electrolyte level. If the electrolyte level is too low, add
•
distilled water to fill up to ½ above the top of the plates
and fully charge the battery. Do not overfill.
Corroded or loose battery tray and hold-down fixture.
•
Tighten or replace as needed.

Testing Out-of-Vehicle

The preferred battery test location is in the vehicle. However, if
you plan to test out of the vehicle:
Always disconnect the negative cable from the battery
•
first and reconnect it last.
Always use a carry tool or strap to lift and transport the
•
battery.
Failure to properly install lead terminal adapters,
or using adapters that are dirty or worn, may
cause false test results.
When testing side-post or Group 31 batteries, always use lead
terminal adapters provided with the tester—do not test at
the battery's steel bolts. To avoid damage, never use a wrench
to tighten the adapters more than ¼ turn.

Testing In-Vehicle

The preferred test position is at the battery posts. If you must
test at a remote-post location, it should have both a positive
and negative post. Otherwise, you must remove the battery
and perform an out-of-vehicle test.
At the start of the test, make sure all vehicle accessory loads
are off, the key is not in the ignition, and the doors are closed.
