Beyond Battery — Cranking & Charging Diagnostics

starter tester cranking cold crank tester

Battery Cranking Tester

Measuring the battery's ability to start the engine by testing voltage drop and crank time during startup. It determines if the battery can provide sufficient power, with significant voltage drops indicating a weak or failing battery. Ensures reliable engine startups, especially in cold weather.

charging system tester alternator tester foxwell

Battery Charging System Tester

Check the health of your battery charging system to prevent overcharging or incomplete charging, which can damage your battery. The tester indirectly evaluates the alternator's performance by analyzing battery voltage fluctuations. Note: The BT301 does not directly test the alternator.
