2) Batteries which test 60% or lower may be:
a. Not fully charged but otherwise in good condition
and still capable of taking a full charge, such as
a new/good battery not yet in service.
b. Fully charged but with diminished capacity due
to age or excessive charge-discharge cycles.
Note: Generally, a battery which has recently
been charged or has been on float charge should
indicate 80-100% for 2-3 tests. Results of 60%
or lower indicate diminished battery capacity.
SLA batteries usually have diminished capacity
after 3-5 years of service depending on ambient
temperatures and the number of charge-discharge
cycles experienced by the battery. New batteries
or batteries that have been stored for an extended
period of time without use will usually not test
above 60-70% until they have been float charged
(30 days) or put through several complete charge/
discharge cycles.
3) If LEDs ‘run’ during a test but no result is displayed:
a. The battery is completely discharged or defective.
b. The MODE is incorrect for that battery.
Techniques for Accurate Test Results
1) Clean connections are important. Verify that the
battery’s terminals are free of any visible contami-
nation or corrosion.
2) Select the proper MODE for the battery. For exam-
ple, select “6V 5-15AH” for a 6-volt, 12 AH battery.
Using the wrong MODE will not harm the tester, but
