Battery Lawnmowers- A Buying Guide

Also known as cordless mowers, battery lawnmowers are becoming ever more popular with gardeners looking to use a greener alternative to petrol garden machinery. The collection system and blade operation works in the same way, just without an engine! Being powered by lithium batteries, users are no longer tied down with a cord from traditional electric plug in mowers.

Things to Consider Before You Buy

As with all mowers, the first thing to consider is the size of the area that needs to be cut. Much in the same way as petrol, battery lawnmowers come in different widths, in both push and self propelled options. Mowers with a wider cutting width will cut the grass much more quickly. However the wider the cut, the heavier the machine is to maneuver so a large cutting width may not be suitable for a small garden.

The size of lawn area will also determine the size of battery that will be needed to complete the cut. The bigger the battery, the longer the run time. Think about roughly how long it would take on average to cut the area and look for battery lawnmowers that have enough running time to match that. Also consider if you have areas of long grass or slopes as this will impact on the amount of energy used by the battery. Some models of lawnmower do have the option of adding a second battery to increase the run time.

Below we have listed the Pro’s and Con’s of owning a battery lawnmower to help you decide if it’s the right option for you.
