A state of charge battery tester is an electric device that is designed to test the life and chargeability of an electric battery. A state of charge tester can provide the current charging state of a battery and its voltage output, while detecting any flaws that may affect the batteries overall performance. Some of the questions that may be answered by a state of charge tester, include:

  • Can the battery be fully charged?
  • Does the charge meet manufacturer’s specifications?
  • How long will the charge last?
  • Do the safety devices all work?
  • Has there been any noticeable deterioration in performance?

State of Charge (SoC)

A batteries state of charge can be determined through on- and offline indirect measurement techniques. The offline technique involves coulomb counting, which involves subtracting the capacity that was taken from the battery over a period of time and subtracting it from the max capacity of the battery. However, this method has errors that occur through every cycle, which must be accounted for. Some of the testing methods for determining state of charge, include:

  • Voltage
  • Pressure
  • Chemical
  • Kalman filtering
  • Current integration

How Does a Battery Tester Function?

A state of charge battery tester tests a battery’s strength by measuring its conductance, which is basically its rated amp output. From there it can be determined if the output of power provided by the battery is sufficient. WirthCo’s Battery Doctor® state of charge tester provides this information with a single push of a button.

If your battery needs charging, simply attach the Battery Doctor® Charger directly to your Battery Doctor® Tester for a simple, tool-free connection. The Battery Doctor® state of charge tester is also reverse polarity protected and comes with a 24" lead and 3 Amp fuse. WirthCo’s battery tester also Works with all Battery Doctor® battery chargers!

Battery Tester Applications

A state of charge battery tester provides peace of mind when traveling or going anywhere where a trusted battery is a necessity. A state of charge tester can provide the current charging state of a battery and its voltage output, while detecting any flaws that may affect the batteries overall performance. Some of the vehicles that can benefit from a battery tester, include:

  • Trucks
  • Cars
  • Boats
  • RVs
  • ATVs
  • Motorcycles
  • And more
