Why Won’t My Lawn Mower Battery Hold A Charge?

If you’re a lawn mower owner, you know how important it is to have a fully functioning battery. Without a reliable battery, your lawn mower won’t start, and you won’t be able to maintain your lawn. However, if you’ve noticed that your lawn mower battery won’t hold a charge, there could be a few reasons why.

1. Age of the Battery

The age of your battery plays a big role in its ability to hold a charge. If your battery is more than three years old, it may be time to replace it. Over time, the chemicals inside the battery break down, and the battery won’t be able to hold a charge for as long as it used to. If your battery is relatively new, it may be a sign of a different issue.

2. Corroded Terminals

Another reason why your lawn mower battery won’t hold a charge could be due to corroded terminals. If the battery terminals are covered in corrosion, it can prevent the battery from charging properly. To fix this issue, you’ll need to clean the terminals with a wire brush and a mixture of baking soda and water. Once the terminals are clean, you should be able to charge your battery properly.

3. Loose Connections

Loose connections can also cause your lawn mower battery to stop holding a charge. If the connections between the battery and the mower are loose, it can prevent the battery from charging properly. Make sure all of the connections are tight and secure before attempting to charge the battery.

4. Parasitic Drain

Parasitic drain is a term used to describe the electrical load on a battery when the engine is off. If there are electrical components on your lawn mower that are still drawing power even when the engine is off, it can drain the battery. To fix this issue, you’ll need to identify the component that’s causing the parasitic drain and fix or replace it.

5. Overcharging

Overcharging your lawn mower battery can also cause it to stop holding a charge. If you leave your battery charging for an extended period of time, it can cause the battery to overheat and damage the cells inside. Make sure you’re following the manufacturer’s instructions for charging your battery and don’t leave it charging for longer than recommended.

Conclusion

There are a few reasons why your lawn mower battery won’t hold a charge, but most of them are easy to fix. If you’ve tried all of the above solutions and your battery still won’t hold a charge, it may be time to replace it. A new battery will ensure you can keep your lawn looking great all season long.
