Battery internal resistance tester

The battery checker performs a measurement of the impedance/conductance and voltage of the battery in order to identify weak cells that may result in the full bank drop. This measurement will not take more than a few seconds per cell and will be accompanied by a sound with the completion of this. On the other hand, the equipment supports cell voltages of 1.2V, 2V, 6V and 12V up to 6000Ah capacity.
