How To Test Gel Batteries. Here the electrolyte is immobilized as gel. For example it may have CCA 70 written on the label.
The resulting figure should be the same as your calculated ampere figure. Because AGM and gel batteries have a sealed case design and lack liquid electrolytes the use of a hydrometer to test the charge status of a battery electrolyte was not an option. Comparing cycle life charts of various manufacturers is not easy to do because each manufactures tests their batteries using different testing parameters to obtain the best results for their product.
An impromptu video looking at some battery testing with the Maynuo M9712.
These cells have 1 14 inch high terminals bringing the total battery height to 9 14 inches. The load tester hooks to the terminals of the battery and displays the voltage. Leave them on the load tester for fifteen seconds. Knowing that we would be unable to crack open the batteries containment cases and evaluate each product from the inside out for obvious reasons we had to come up with our own non-destructive test.
