Best Lawn Mower Battery Charger Buying Guide

Best Lawn Mower Battery Charger

There are a wide variety of battery chargers for lawn mowers in the market. But most of them aren’t worth your time or money. That’s why in the following guide, we will discuss the various features of a battery charger that make it worth considering.

Let’s begin: 


Safety is one of the most prominent factors that you need to consider before purchasing a lawnmower battery.

You have to check whether the power output of the charger is compatible with your battery or not. Typically, lawnmower batteries have a voltage of 6-12V. And their amperage can range from 5Amp-25Amp. 


A lot of customers don’t even think about this feature while purchasing a charger. But having indicators on the charger will help you get an idea about the battery’s capacity while charging. 


You may need to carry the charger around from one place to another, so you should buy a portable charger. It should have a compact design, and it should also be lightweight.

When Should You Replace Your Lawn Mowers Battery Charger?

Whenever your battery runs out of charge, your lawnmower battery charger revives it by recharging it and getting it ready for use. However, if the battery charger is faulty, it won’t be able to charge the battery properly. 

A poorly charged battery won’t be able to provide you with the runtime that’s expected of the battery. And if that happens, you should test your battery charger in order to figure out whether or not it’s the right time to replace your lawn mowers battery charger.

At first plug the charger to an electric outlet. Then take a voltmeter and plug the test probes into voltmeter. After that connect the battery to the battery charger. Now take your battery and connect the positive end of the lawnmower’s battery to the red probe of the voltmeter. 

And connect the black probe to the negative side. Now check the reading of the voltmeter. If the pointer of the voltmeter points to the right side, then that means that the battery is receiving charge and it’s working just fine.

In contrast, if the voltmeter doesn’t show any reading, that would indicate that your battery charger is faulty and it needs to be replaced.
