How To Check Battery Internal Resistance. To test internal resistance you need to load the battery at least to Ah rating If it is something like a golf cart a wheel chair scooter. Failure to recalibrate the system may result in overcharging of the new battery by the alternator resulting in battery failure.
Failure to recalibrate the system may result in overcharging of the new battery by the alternator resulting in battery failure. That is also how we can measure the internal resistance of a battery. The internal resistance of a battery can be tested in 4 steps1 measure the voltage V_bat of the battery2 measure the resistance of an external load R_e.

Internal resistance gets lower when the battery temperature increases. The high speed of a 1000 Hz test a portion of the ionic resistance factors may not be fully captured. 2 The internal resistance of the battery is the key to determine the size of the batterys resistance to charge and discharge current. Measuring Internal Resistance of Batteries.
