How Do You Maintain Your Lawn Mower Battery in Winter?

Maintaining Lawn Batteries in Winter

Batteries used in machines need to work during the winter months, but that can sometimes be a challenge. They must go into the season fully charged, or else they can struggle to turn on. Generally, batteries below a 70 percent charge tend to have difficulties starting. This is typically for cold engines.

Also, because of the temperature, batteries produce less energy at colder temperatures and the overall state of charge lowers as well. Since battery replacements can also be difficult in the cold weather, you will want to make sure you are being preventative, which will make it much easier to keep your equipment maintained.

Let’s take a look at some of the steps that can help you be preventative with your machine batteries.

Perform a Load Test

Load-testing your batteries will be a necessity, so you can make sure they are ready to perform before you start your engine.

Fully Charge Your Batteries

Batteries should be fully charged before they are placed into storage. If they are not fully charged, you will want to make sure they are at least above a 70 percent charge.


Batteries are likely to discharge over time, however, lower temperatures actually slow the process. If you do not plan on using your equipment, it’s a great idea to consider storing it in a cool, but not freezing, location.

Disconnect Negative Ground Cable

Operators must disconnect the negative ground cable. In addition, this helps to reduce discharge caused by electrical components. You will want to restore this cable before the end of each season.
