How Long Do Lawn Mower Batteries Last?

It’s your day off today. The sun is shining and the grass is rustling in the breeze. It’s a nice day, but the lawn’s been bothering you for days. Today’s the day to tackle it. It may not be ideal, but at least you can anticipate the satisfaction of a job well done.
You’re cutting neat rows into the overgrown greenery with your mower when the battery dies.
The situation is frustrating for nearly every homeowner. But there’s good news: you don’t have to give up on your lawn mower halfway through. You can make a big difference by choosing the right battery. That brings us to the topic of this blog post: how long do lawn mower batteries last. Find out which lawn mower batteries are the longest-lasting by reading on!

Ways To Power A Lawn Mower

First, let’s discuss the different types of lawn mowers before we discuss how long a lawn mower battery will last. High-powered riding mowers can handle acres of land, while simple push mowers are good enough for those with a small yard to maintain. Then there are self-propelled mowers, zero-turn mowers, electric mowers, and a variety of others.
Gasoline, corded electric power, battery power, or a combination of gas and electricity are the main ways to power a lawn mower. There are some disadvantages to gas-powered mowers, however. You’ve got to keep gas and oil on hand and know how to mix them up correctly. You also have to start your engine with that pesky pull string.


People with very small yards can benefit from corded electric mowers. However, mowing with extension cords can be very frustrating. They can unplug at the outlet or at the lawn mower, and they can also get caught or tangled in yard items such as bushes, trees, or power boxes.
Mowers powered by batteries have a lot of advantages. You can skip trips to the gas station and avoid spills in the back of your SUV. But they aren’t the best option for lawn care workers or homeowners with small yards.
Many people prefer gas-powered mowers with electric starters, especially when they have riding mowers and zero-turn lawn mowers. With a battery-powered starter, you don’t have to fight the pull string. Just press a button or turn a key to start your lawn mower. Now, the big question remains: how long will a lawn mower battery last? Keep reading to find out.

How Long Do Lawn Mower Batteries Last?

Buying a lawn mower that can handle larger properties can be a big investment. A push mower will drain all your energy. For bigger properties, riding lawn mowers (or better yet, zero-turn mowers) are usually the best option. These internal combustion engines require a starter battery. Bringing us to our topic: what kind of lawn mower batteries are best and how long do they last?
The best mower for you will depend on a number of factors: whether it is for residential or commercial use, how often you mow, and whether you would rather spend less in the short term or save more in the long term.


The first type of lawn mower battery is cheap, but it is often very heavy, requires a lot of maintenance, and has to be replaced more frequently. We’re talking about lead-acid batteries.
A lithium LiFePO4 lawn mower battery costs more up front, but weighs about 50% less than lead-acid batteries, lasts 4-6 times longer, and requires no maintenance.
Buying replacement lawn mower batteries can be expensive, so it’s important to have batteries that will last as long as your mower.

The Battery With The Longest Life-Span

The lifespan of lead-acid batteries can be quite variable depending on how well they are taken care of. Without maintenance, they only have a life expectancy of one mowing season. To ensure their longevity, it is advised that you purchase a trickle charger at the end of each season. It should also be noted that these batteries struggle to survive in winter conditions. As such, manufacturers measure them in charging cycles; with proper care, you may get up to a few hundred out of them. However, it is important to note that this depends entirely on their storage too.
Lithium batteries can last for 10+ years or 3,000 charging cycles at 80% DOD. Lithium batteries have a higher power density level and a slower rate of capacity loss than lead-acid batteries.
If you ask yourself “how long does a lawn mower battery last?”, you will find many answers. As you can see, lithium lawn mower batteries can last much longer than lead-acid lawn mower batteries. They last 4-6 times longer than lead-acid batteries!

Advantages Of Lithium Lawn Mower Batteries

In addition to their longevity, lithium lawn mower batteries offer several other advantages over lead-acid batteries.
Lithium batteries have a built-in battery management system (BMS), so they won’t overcharge or overheat on the charger, unlike lead-acid batteries.
Batteries made from lithium have a 15x lower discharge rate, hold their charge longer, and charge four to six times faster than lead-acid batteries.
You can store them indoors since they are non-toxic.
As opposed to lead-acid batteries, they require no maintenance.
As a result, lithium batteries have a 15x lower discharge rate, hold their charge longer than other batteries, and charge 4 to 6 times faster than lead-acid batteries.
Due to the battery reserve, these batteries have an emergency start feature! Simply press a button and your battery will start up again!
Lead-acid batteries are 70% heavier than lithium batteries.


It’s clear to see why lithium LiFePO4 batteries are the number one choice when it comes to rechargeable lawn mower batteries. If you run a landscaping business or have a large area of land, then these batteries will prove more than useful – they will be a game changer. The Ionic batteries come equipped with an Emergency Start function and Bluetooth technology, so you can keep on top of your battery stats and make sure you won’t run into any unexpected dead starter battery problems. Lithium lawn mower batteries really stand out from the crowd.
