How to Test A Deep Cycle Battery with A Multimeter

Do you know the capacity, quality, and effectiveness of your battery? Almost people who are using deep cycle battery they do not know about their battery. They are not well aware of this fact. They just use of power when they need. They do not calculate its power, voltage and negative positive side. It may happen serious accident and can be reason of life spoilt. Because deep cycle battery is a lead acid battery and we know that acid accident is not expectable at all. So, we need to be aware and to learn the testing process of deep cycle battery.

I am going to discuss here how to test a deep cycle battery with a multimeter. This is much important to know for a battery user.

Take the measurement of Charge

Step 1 #

test a deep cycle battery with a multimeter

Firstly, take the reading of voltage capacity and temperature of the battery. Deep cycle battery shows the reading of State of Charge(SoC) of several types battery. Without charging the SoC will be more than three fourth that means 75 percent when it is in rest position for two to eight hours.

Step 2 #

Main battery test

Switch off the fuel supply and turn over engine with starter motor for near about fifteen seconds. Take the lowest voltage during this cranking.

Step 3 #

Battery Capacity test

Battery Capacity test

Slowly connect, medium load and take the reading how much power it discharges. Load recommended two capacities is 2:5. Discharge testing of batter is to set with DC ammeter. It can measure voltage and current in every frequent.


Electrical power energy and deep cycle battery are always high risky to handle. You are requested to handle it with great care. If you don’t feel flexible to handle it, please don’t do that. I will not responsible for any accident and loss occurs by following this instruction.

For the better test reading an excellent quality multimeter required. Hope so it will give you a best experience of deep cycle battery testing. Good wishes to you all for happy energy or deep cycle battery using.
