The most critical aspect of evaluating true health of a battery are the measurements of the internal cell conductivity of each individual battery. These measurements are important because over the life time of the battery it allows us to recognize the degradation and eventual failure of the internal cell conductivity.  Correctly and accurately capturing these measurements for gathering of historical battery information to predict the health and service life of a battery must be of topmost importance.

Therefore, here are few recommendations Midtronics provides to accurately capture these data points when utilizing a Midtronics battery tester:

Do not place clamps or probes on stainless steel hardware, such as bolt heads, washers, or threaded posts. Stainless steel hardware can yield low conductance values. If you must test on stainless steel, record it in your testing records.

The jars might have grease on the terminals and connections to prevent corrosion. You do not have to remove the grease before attaching the clamps or connecting the probes

Test each jar in the same location or position. Changing the location of the test (contact) point might vary test results.


By avoiding lower or incorrect measurements, you will have the most consistent and reliable results.
These actions will help you to create a precise internal conductivity trend to indicate battery performance against the battery baseline. Historical information will also help you verify the battery is or is not performing as manufactured.
