One of the most noticeable signs that your lawn mower battery needs replacing is a significant decrease in running time. If your mower runs out of power quicker than it used to, even after a full charge, it’s likely that the battery is no longer able to hold a charge properly. Over time, batteries naturally lose their capacity, and this manifests as shorter run times. When the mower's battery can no longer sustain long enough power for your lawn’s size, it is time to consider a replacement.
What to Do: If you find that your lawn mower is running out of power prematurely, it’s time to inspect the battery for wear or age-related degradation. If the battery is old, replacing it with a new one will restore your mower's full power capacity.
Another common indicator that your lawn mower battery may need replacing is slow charging or, worse, complete failure to charge. When you notice that the battery is taking much longer to reach full charge, or it doesn't charge at all, the battery could have a faulty internal component or reduced capacity. Sometimes, slow charging may be due to a charger issue, so it’s worth testing the battery with a different charger to rule that out. However, if the problem persists, it could indicate that the battery itself is failing and needs to be replaced.
What to Do:
● First, test your lawn mower with a different charger to ensure the charger is not the issue.
● If the problem persists after changing the charger, it is likely that the battery is no longer functioning properly and should be replaced.
Physical damage or leaking from a battery is a serious problem that should be addressed immediately. A lawn mower battery that shows signs of physical damage, such as cracks or dents, can be a safety hazard. In addition, batteries that are leaking fluid can cause severe damage to the internal components of your mower, as well as potentially corroding other parts. Leaking is often a sign that the battery is nearing the end of its life, and continuing to use it could result in more severe issues or even pose a risk to your safety.
What to Do:
● If you observe visible damage or leaking, stop using the lawn mower immediately.
● Dispose of the damaged battery safely, following proper recycling procedures, and replace it with a compatible, high-quality battery to avoid further damage to your mower.
