How Long Do Electric Lawn Mower Batteries Last? A Comprehensive Guide

Electric lawn mowers are becoming increasingly popular as a convenient and environmentally friendly way to maintain a beautiful lawn. However, the longevity of the batteries in these mowers can be a source of concern for many homeowners.

In this article, we will explore how long electric lawn mower batteries last, what affects battery life, and what steps can be taken to maximize the life of your electric lawn mower battery.

How Long Do Electric Lawn Mower Batteries Last?

Having a bad electric lawn mower battery can be one of the most frustrating parts of lawn care. There can be several signs that indicate your lawn mower battery is not performing as it should. These signs include a weak start, slow cranking, dim lights, and corrosion.

A weak start is when the mower struggles to turn on, and the engine takes a while to get going. Slow cranking is when the mower takes longer than normal to start. Dim lights can be a sign that the battery is not providing enough power and can also be a sign of corrosion. Corrosion on the battery terminals can be caused by acid buildup and can prevent the battery from working correctly.

If your electric lawn mower battery exhibits any of these signs, it’s time to consider replacing it. The good news is that electric lawn mower batteries are fairly easy to replace, and a few different types of batteries are available.

The most common type of battery is the lead-acid battery, which is relatively inexpensive and easy to find. Lithium-ion batteries are becoming increasingly popular and are generally more expensive than lead-acid batteries.

The life of an electric lawn mower battery depends on various factors, such as the type of battery, how often it is used, and the temperature and humidity of the environment. Generally, lead-acid batteries can last up to three years with proper care and maintenance. Lithium-ion batteries can last up to five or six years. It is also important to note that electric lawn mower batteries should be stored in a cool, dry place when not in use.
