If you have a regular lawn, the most convenient lawn mower you can have is the battery-powered one. You don’t have to spend money on gas and you are not limited by a cord. You just need to charge the battery.

How Long Does It Take to Charge a Lawn Mower Battery?

It can take anything from 30 minutes to six hours to fully charge a lawn mower battery depending on the battery type and the age of the lawn mower. New battery-powered lawn mowers are fitted with more advanced batteries than can be charged in just half an hour. The higher the Ah number on a battery, the more capacity it has, so it can run for longer, but will also take longer to fully charge.

Battery-Powered Lawn Mowers

There are many different kinds of lawn mowers in the market. But one thing is for certain, the battery-powered ones are the most convenient. 

However, it’s not for all lawns. Battery-powered lawn mowers are best for regular lawns, by that, we mean the backyard lawns of regular homes and not the large ones in mansions and commercial spaces. 

Why are they convenient?

First off, you don’t need gas and oil to make it function. This means that you can save money, too. 

Plus, the maintenance isn’t much of a hassle since you don’t need to change the oil regularly. 


There are no cords to contend with. Cords are sometimes the bane of mowing since they could trip you up while doing so. 

Or the mower could get tangled just because you made a wrong turn. 

Here’s more:

These mowers are so much easier to start. There are also different ways to make them start–some just have the push button, others use a key, while some make use of a lever. 

They are also lighter and easy to store. A lot of battery-powered machines are collapsible for easy storage. 


It’s not noisy at all. You won’t feel bad if you mow the lawn any time of the day–whether it’s too early in the morning or super late at night.

You are not going to disturb your neighbors who might still be sleeping or those who just crave peace and quiet throughout the day. 

But it’s not perfect

The main issue with battery-powered lawn mowers is its power provider–the battery. Much like iPhone batteries, lawn mower batteries don’t last too long. 

That’s why we emphasized that this is great for smaller lawns since you are bound to experience a dead battery in the middle of mowing when you have a large grassy yard. 

Here’s the scenario

You are mowing the lawn. Just when you are about to finish up, the battery is dead. But you were so close.

Wouldn’t that be the most annoying thing?

The best thing you can do is to prepare a spare battery or batteries so that you don’t have to wait for your lone battery to fully charge before you continue mowing the lawn.

That’s why it’s essential that you know the answer to this question: How long does it take to charge a lawn mower battery?

By the way

Battery-powered machines are environmentally friendly. They have zero emissions so you don’t have to worry too much about adding to the destruction of the environment.  

Charging a Lawn Mower Battery

When you buy a battery-powered lawn mower, it already comes with a charger. 

When do you charge the battery or batteries?

  • Before you use the lawn mower for the first time. 
  • Before you store the lawn mower for winter. 
  • When the battery is dead – this happens fairly often during spring and summer months when the grass is continuously growing. 

If you have old mowers

Then your batteries may already be dead. If not, they wouldn’t last for too long. 

The problem with old battery-powered lawn mowers is that they didn’t have a mechanism to stop the battery from being overcharged. 

What happened then?

When batteries overcharge, they won’t last as long as they used to. 

There was also a tendency that toxic gasses were released during the process of overcharging. 

Good thing:

Batteries and chargers of new lawn mowers have been improved over the years. The current battery chargers already have a system that would prevent overcharging.

This way, in case you get too busy and forget to unplug the charger, your battery won’t be damaged and will continue to work as it should. 


You don’t have to worry about toxic gasses that would be emitted from overcharging. 

Chargers also went through innovation and some of them can charge batteries quickly. Not too quick that they are no longer annoying, but at least, you won’t have to wait for hours before the battery gets fully charged. 


If you could choose your own charger, you need to invest in one that has a lot of beneficial features. 

Chargers already come with the lawn mower. But if you are not satisfied with the free charger, you can always buy one. 

Here are some important features of a good lawn mower battery charger:

  • Different mode settings: slow, fast, and jumpstart.
  • Hookup failsafe – to ensure that you won’t connect it to something incompatible.
  • Automatic shutoff system.
  • Controlled amp rates.
  • Various clamps for different connections.

How do you charge properly?

Every lawn mower has a booklet that indicates how to charge the battery step by step. The first step is always to check if you have the right charger. 

Sure, a charger comes with the lawn mower when you buy it. But you can never be too sure that the person who packed the set included the right charger. 

Basic steps to charging a battery

  1. Wear gloves (safety glasses would be good, too). In most cases, you need to get your hands inside the machine in order to connect the charger. It’s just better to be safe. 
  2. Locate the battery. 
  3. Connect the positive side first. By the way, at this juncture, the charger should not be plugged to the outlet. 
  4. Connect the negative side. 
  5. Input the appropriate setting. 
  6. Plug the charger. 
  7. Wait for the battery to fully charge.

Charging Time: What to Know

How long does it take to charge a lawn mower battery?

The answer is found in your instructions manual. Different lawn mowers require different charging times. 

But if you want a range

Charging could go as fast as 30 minutes or as long as two hours. But if we’re talking about the older generation, charging time could go as long as six hours.  

The difference in charging times are due to two components:


Current models of battery-powered lawn mowers run on 12V batteries. The older models use 6V. 

You have to check the voltage and use the charger that matches your mower’s voltage.


The amperage refers to the speed that the battery can charge. However, for lawn mowers, the charger cannot go more than 10 amps. 

Ten is the maximum amperage you can use or the battery will be damaged. 

Let’s be more specific

Just to give you an idea of the specific charging times, here are some of the best battery-powered lawn mowers in the market:

Usually, it takes between 30 minutes to a couple of hours to fully charge a battery. But if you have an older model, it could take between four and six hours. That’s what’s great about the new models, they charge faster and they have a mechanism that batteries won’t overcharge.
