How To Keep Lawn Mower Battery Charged

1. Charge it Often

The best way to ensure the lawn mower battery is always charged is to charge it often. Make a habit of plugging it in after each use, and it will be ready to go for the next time you need it.

You may also want to consider investing in a battery charger, which will allow you to keep the battery topped off even when you’re not using the lawn mower.

Occasionally, checking the battery will also help you stay on top of any potential charging needs. If the battery is low, you can easily bring it back to full power with a battery charger.

2. Clean the Battery Terminals

It’s also important to keep the battery terminals clean. Corrosion on the terminals can prevent the battery from charging correctly.

Use a wire brush to clean off any corrosion, and then apply a light coating of petroleum jelly or silicone grease. This will help keep the terminals corrosion-free and allow the battery to charge properly.

3. Keep the Battery Cool

Extremely high or low temperatures can also adversely affect the lawn mower battery charge. Make sure to keep the battery in a cool, dry place when not in use.

If you’re storing the lawn mower for the winter, consider putting the battery in a cooler place in the house to help keep it from freezing.

4. Fill the Battery Up

One way to ensure the battery is always charged is to fill it up. Make sure the battery is full before using it. This will help ensure that you get the most out of the battery and that it will last for an extended period.

It’s also important to check the water levels in the battery. If the water level is low, add distilled water to reach the full line. This will help the battery stay charged and prevent corrosion.

5. Use the Right Kind of Battery

Not all lawn mower batteries are created equal. Make sure to use the correct type of battery for your model.

Using the wrong battery can not only damage the lawn mower, but it can also prevent the battery from charging properly.

Most lawn mowers use a 5 to 12-volt battery. Make sure to check your lawn mower’s manual to determine the battery’s voltage you need.

6. Avoid Overloading the Battery

Another critical factor in keeping the lawn mower battery charged is avoiding overloading the battery. When the battery is overloaded, it can’t charge properly and will eventually die.

Make sure to only use the lawn mower for its intended purpose. Don’t run the edger or blower off of the same battery – this will quickly drain the battery and cause problems.

1. Leaving the Mower Unplugged

Leaving the mower unplugged can also drain the battery. Make sure to always unplug the charger when you’re done using it. If you don’t plan on using the lawn mower for an extended period, consider removing the battery and storing it in a cool, dry place.

2. Ignition Switch is Left On

Another common culprit is the lawn mower’s ignition key switch. When the key is left in the on position, it can quickly drain the battery. Make sure to turn off the key switch when you’re done using the mower.

3. Using the Mower for too Long

Using the mower for too long can also drain the battery. If you’re going to be using the mower for an extended period, take a break every so often to let the battery recharge. This will help ensure that you don’t run the battery down.

4. Faulty Voltage Regulator

If your lawn mower battery is not holding a charge, it may be due to a faulty voltage regulator. A voltage regulator is responsible for maintaining the correct voltage level in the battery.

If it is not working properly, it can prevent the battery from charging correctly. If you suspect that your voltage regulator is not working properly, you can test it using a voltmeter.

5. Damaged Battery

Finally, if your lawn mower battery is not holding a charge, it may be due to damage. If the battery is cracked or damaged, it will not hold a charge. If this is the case, you will need to replace the battery.

Hi, I’m Ricky. I’ve been involved in lawn care and landscaping from when I was 15. To be honest, I didn’t like the idea of pushing mowers, collecting grass clippings, and maintaining flowerbeds at the time. But having seem the passion my parents had for gardening and outdoors and the effort they put in maintaining the health and beauty of our landscape, I couldn’t help but not only admire their hard work but also I became a part of it. As someone who loves to spend time with nature’s best, I find myself learning a lot more about gardening and outdoors on a daily basis. Not to mention I love to share the knowledge I’ve gathered over the years with my readers at We Mow Dallas. To be clear, I don’t have a Master’s degree in gardening or anything like that. Everything I’ve learned about gardening, landscaping, and lawn care spring from passion and engagement with my parents. And with a ton of free information out there, plus the ability to run tests and determine what works best for lawn care and landscaping, every day is an opportunity to learn and implement something new. My goal with We Mow Dallas is to teach you exactly how to maintain your lawn and landscape. And since I walk the talk in reality, you shouldn’t hesitate to join me in this wonderful world of landscaping and lawn care.
