Information on battery testing, battery testers and most importantly what separates the SOC testers from the rest of the pack.

When you are looking for a battery tester for UPS backup or emergency system testing, there is little room for error.  The consequences of choosing the wrong piece of test equipment could end up costing you thousands of dollars due to false positives, or unnecessary battery replacement costs due to false negatives.  In the case of emergency systems the results can be catastrophic.  Make sure you have the power you need when you need it the most, trust the equipment professionals trust.
If you are only testing voltage with a multi-meter, you are wasting your time.  You are most likely just reading the surface charge off the battery from the charging system.

If you have been exercising the 90 minute test, you are unnecessarily depleting the battery and consequently shortening its life.  You are also leaving the ups system in an unnecessary depleted state.  Another downfall could be inaccurate readings based on the time left for voltage increase between load and voltage analysis.

Every other field testing method and tester we have evaluated has inaccurate and inconsistent results.  Don't don't take our word for it.  Ask any tech using such devices and testing methods if they agree.

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 with temperature.

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
