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 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.
Test Result Interpretation
1. First green LED indicates full strength battery.
2. Second green LED (80%) indicates less than full-strength, but
suitable for use.
3. First yellow LED (60%) indicates that battery may be used only
if a stronger one is not available.
Note: A battery indicating less than 100% may cause reduced opera-
tional capability.
Tips for Better Testing
1. Clean connections are important. Verify that the battery’s terminals
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 batter-
ies (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 bat-
tery on the test terminals, then gently twist the battery against the
tester’s terminals to maintain a good connection.
