What Voltage Are Lawn Mower Batteries

Like most homeowners, you probably dread mowing the lawn each week, which could be tedious and time-consuming. Fortunately, there's a way to make it easier. All you need is a good-quality lawn mower battery that will determine how powerful the machine is. Understanding the voltage of your lawnmower battery is essential to choosing the correct charger and keeping your engine running at its best. So, keep reading to learn more.

Is a riding lawn mower battery 6 or 12 volts?

A riding lawn mower battery is a 12-volt battery. However, some riding lawn mowers use a 6-volt battery. The voltage on a riding lawn mower determines the strength of the electric current going to the motor. A 6-volt battery usually powers the headlights, taillights, and blinkers on a riding lawn mower, while a 12-volt battery powers the electric starter, ignition system, and other accessories on the engine.

How do I know if my lawn mower battery is 12 volts?

Here are the ways to determine and find out the voltage of your lawn mower battery:

Check out the mower's manual: One of the best ways to know what voltage is your lawn mower battery is by checking the mower's manual. The manufacturer has listed the required voltage for the model you have.

Look at the sticker on the battery: To find out what voltage your lawn mower battery is, check the label on the side part of your battery.

Count the number of cell cups: You can determine by counting the number of plastic cups in the battery and multiplying it by two. A 12-volt battery has six cells, while a 6-volt battery will have three.

Measure voltage with a voltmeter: You can measure the voltage using a voltmeter. To do this, touch the positive and negative leads of the voltmeter to the corresponding terminals on the battery. Most auto parts stores test the batteries for free if you don't have a voltmeter.

Can you charge a lawn mower battery with a 12-volt charger?

 A 12-volt battery charger can be used to charge a 12-volt lawn mower battery. Remember that using a charger with a higher voltage could damage your battery since they are not explicitly made for lawn mower batteries. Always read the voltage requirements before purchasing a replacement battery to avoid buying one that is too high or low for your machine.

Can you charge a lawnmower battery with a car?

Yes, you can charge a lawnmower battery with a car, but it isn't recommended since the car batteries are designed to deliver higher power, and lawnmower batteries are not.

Therefore, charging a lawnmower battery with a car can damage the battery and cause the battery to explode. That said, it's best to charge it with a 12-volt battery charger designed for lawnmowers. To do this, attach the clamps to the battery posts using the red clamp for the positive post and the black clamp for the negative post. 

Conclusion

Lawnmower batteries come in various voltages, so it is crucial to choose the right one for your needs. Higher voltage batteries provide more power and last longer between charges, but they may be too powerful for smaller lawns. As a result, it would damage your mower and may incur an explosion. Thus, ensure you get the perfect voltage match to make its lifespan longer.
