Ermenrich Zing AL45 Battery Tester

The Ermenrich Zing AL45 Battery Tester is an intuitive tool that enables you to quickly check the condition of the car battery or the uninterruptible power supply (UPS). The tester connects to an anode and cathode with two terminals. It is also the same way that the tester is charged – no other power supply is required.

The tester readings appear on the built-in screen. The top bar shows the overall battery health status in percentage. If the value is between 40% and 60%, it is time to think about battery replacement, and under 40% indicates a loss of battery performance. All values above 60% are considered to be good. The screen also shows the voltage, internal resistance, and cold cranking amps (CCA). The controls are located below.

Key features:

• Shows the overall battery health status in percentage


• Measures voltage, internal resistance, and cold cranking amps (CCA)


• Charging via the battery under test (no additional power supply needed)
