TOPDON BT100 Cranking Test

If your battery is 4 or more years older, and it does not seem to crank your engine at a normal speed, you probably need a new battery.

This 12V battery tester can show you the cranking voltage, and the cranking time in milliseconds, to help predict if the battery will fail to crank/start the vehicle.

Loaded Voltage means the voltage measured when turning on on-board electrical appliances, such as headlights.

Unloaded Voltage means the voltage measured when turning off all the on-board electrical appliances.
