3. Hold contact firmly throughout the entire test cycle (during ‘run-
ning’ LEDs), then continue to hold contact to display the test
result.
4. Lift the probe or battery to end a test. Repeat test for best ac-
curacy.
5. When testing rechargeable type batteries (NiMH & Li-Ion), it is
recommended that the battery be off the charger for at least 20
minutes prior to testing.
To test CRV3 and 9-volt batteries, note the polarity then hold the
battery against the appropriate twin terminal set.
The display will remain lit until the battery is removed from the tester’s
terminals. This does not harm or drain the battery being tested.
Tips for Better Testing
1. Clean connections are important. Verify that the battery’s termi-
nals and the tester’s contact terminals are clean before making
a test. We recommend periodic cleaning with 91% isopropyl
alcohol and soft cloth. This is especially important when testing
rechargeable batteries (NiMH & Li-Ion) since they are generally
handled more frequently which can result in contamination on
the terminal surfaces. It is also important to periodically clean
the battery charger’s contacts.
2. If a battery slips off the terminal during the test cycle (‘running’
LEDs), wait several seconds, then start a new test.
3. When testing 9-volt batteries, an easy technique is to place
the battery on the test terminals, then gently twist the battery
against the tester’s terminals to maintain a good connection.
4. Used batteries may ‘recover’ when rested. For best accuracy,
always make two or more consecutive tests to verify that the
battery has stabilized and is capable of consistent power output.
Wait several seconds between each test.
5. Certain new batteries may test less than full capacity new out-of-
the package. This may be due to the battery’s chemistry not fully
activating. Try several tests or warm the battery in your hands for
a few seconds. Not all new batteries are at full capacity.
