Which one is the the number … WebMay 9, 2024 · The lower amount of internal resistance depends on the individual circuit. Suppose you have a typical battery pack of 1300 to 1500 mAh capacity. For that much capacity, the internal resistance of the circuit should be lower than 10 to 15 m Ohm. Once the battery starts to get old, the internal resistance will rise to 15 to 20 m Ohm. WebMay 4, 2024 · Test a car battery using a multimeter by putting Load. Load is applied to the battery while its voltage is monitored. You can do this by starting the engine, turning lights on and monitor the voltage with a multimeter that has a min/max mode. This will automatically store the high and low voltages it picks up. nutrien campbell town

WebThe same is true when measuring battery voltage to determine if a battery has gone bad. Fully-charged, most car batteries will measure at least 12.6 volts (~13.0-13.2V for OPTIMA YELLOWTOPs), but low voltage doesn't necessarily equal a bad battery. Modern cars are very demanding from an electrical perspective, even when they're not being used.
