Lithium Battery Lawn Mower- Operation, Cycle Life, and Care

Aug 01, 2020   Pageview:88

Lawnmowers are very essential tools in our homes and any other places that need frequent lawn maintenance. Some lawnmowers are powered by gasoline, some are manual, and some are powered by electricity. The choice of the one you buy depends and what you want to accomplish, your budget, and the energy source that is convenient for you.

Electric lawnmowers are normally powered by Lithium batteries that come along with the lawnmower when you purchase it. The life of these batteries largely depends on how frequent the mower is used and the charging habits of the user. In today's article, I am going to share with you everything you need to know about lithium battery-powered lawn mowers – how they operate, maintenance and their life cycle

What is the best battery-operated lawnmower

The best battery-operated lawn mower is one that not only fulfills your needs but also fits in your budget for both procurement and maintenance. Here are some of the key things you need to look at while choosing the best lawn mower for yourself;

The battery capacity

This is one of the key factors that you need to look at because it is what determines how long you will do the mowing before having to recharge. While choosing a lawnmower, you need to get one with at least 5AH if you want to mow for at least an hour before having to recharge. The battery usage also depends on the amount of energy required by the mower to get the work done.

Height of the deck

Lawnmowers are designed with different deck heights that you need to take into consideration before choosing one. The deck height of the lawnmower is what determines its cutting height. You need to base on the height of your lawn to know which deck height would be suitable

. But normally, a lawnmower with a steel deck height of about 17 to 22 inches will always do a good job especially if this height is adjustable

How the mower is propelled

Lithium battery-operated lawnmowers are propelled in two different ways i.e. self-propelled and manually propelled ones. Self-propelled mowers are those that have powered rear wheels. in this case, your work is only to give the lawnmower directions and regulating speed. For manual ones, you will have to manually push, pull, and also give direction to the lawnmower during mowing.


Manually propelled lawn mowers are cheaper than self-propelled ones but their efficiency largely depends on your energy. The ideal option should be self-propelled lawn mowers if you can afford them.

How long does a lithium battery lawn mower last

The life of a lawnmower depends on how you care for it and its build quality. A good quality lawnmower that is properly cared for should last you between 8 to 10 years. However, you may have to replace its battery after about five years. This is because the lithium batteries for lawnmowers lose at least 5% of battery capacity each year. So, after 5 years, the battery may not be able to give you enough time on a single charge

How do you care for your lithium battery lawnmower

Taking care of the lawnmower will increase its longevity and also maintain good performance for many years. Here are some of the tips you can use to increase the lifetime of your lithium battery lawnmower.

Always sharpen the blades at least once a year. This is because the blades become blunt as you continue to use the lawnmower over time. Sharpened blades will make the lawnmower more efficient and also save time while mowing

Avoid mowing wet grass as this will damage the cutting blades of the lawnmower in the long run.

Always clean the deck after use to remove any grass and debris that might be stuck under the lawnmower before storing it.

Don’t leave the battery uncharged for more than 2 months. This is because the battery loses its capacity when it gets extremely low

For better battery life, also keep the lawnmower in an environment that is within room temperature. Storing the lawnmowers in a place at high temperatures reduces its battery life in the long run.
