VRLA or valve regulated Lead Acid, Flooded Lead Acid, Nickel Metal Hydride, Glass Mat AGM batteries, and Gel Cell Batteries. Not Lithium since they employ battery management systems. Answered by: FlukeCorp.
Since current flow relates to ohmic value, most CCA testers measure the internal battery resistance. To test the CCA with a carbon pile, a battery that must have an SoC of 70 to 100 percent. It is then loaded with half the rated CCA for 15 seconds at a temperature of 10º C (50º F) and higher. ... @Brian: in a Lead Acid Battery there is the ...
