Battery Tester

A battery tester is an essential diagnostic device used to assess the condition and performance of automotive batteries. As modern vehicles rely heavily on electrical systems, maintaining a healthy battery is crucial for optimal vehicle functionality. Battery testers provide quick and accurate measurements, allowing technicians to identify battery problems before they lead to unexpected breakdowns.

How a Battery Tester Works

Battery testers analyze the electrical characteristics of a battery while it is installed in the vehicle. By measuring multiple performance indicators, the tester determines whether the battery can reliably start the engine and power the onboard electronics. Advanced models also perform system-wide diagnostics on the alternator, starter motor, and charging system to ensure everything operates properly.

Key Testing Parameters

• Voltage Level
  Measures the battery’s state of charge and its ability to supply power.

• CCA (Cold Cranking Amps)
  Evaluates the battery’s ability to start the engine under extreme cold conditions.

• State of Health (SOH)
  Indicates the overall condition of the battery and expected lifespan.

• State of Charge (SOC)
  Shows how much usable energy remains inside the battery.

• Internal Resistance
  Helps detect deterioration, corrosion, or internal faults.
