Size does matter! Testing a battery with a load tester and notice that the test cables seem a little inadequate to do the job? Too thin to sustain the current necessary to apply the load? If it's really a load tester, how much of a load can it put on the battery with such thin cables?
No adjustment for exact AHR setting on the tester you are using? Results are pretty much guaranteed
to be inaccurate.
If you are testing with a load tester, make sure the testing device you are using has compensation built in for temperature.
Load level application and evaluative criteria may fluctuate
Without temperature compensation, "state of charge" results could be off by 20-50% depending on the temperature of the battery under test. Find out more
