Using a multimeter

Connect the probes of your multimeter to the appropriate terminals of the battery. Give it a small load to read voltage drop. Make sure your device is configured to read up to 20 DC volts.

Using a hydrometer

Use the hydrometer to measure the density of the battery’s electrolytes. You must read the specific gravity on each cell and compare it to the readings on a chart.

Using the Load Testing method

The load tester offers more insight by putting a dummy load on the battery. You hook the load tester to the battery terminals and read the voltage. Then, press the button to put a load on the battery and watch the voltage. It shouldn’t drop more than 0.4 volts.

Using the Discharge Testing method

This expensive method requires special equipment, normally only owned by repair shops. Hook the unit across the battery bank and put them under a resistance load. You will learn the health based on the rate of decay over the time it takes to deplete 75% of the charge.
