What is the best battery-powered lawn mower? The first feature to consider is the type of battery. You will have 3 options: lead-acid, Nickel-cadmium, and Lithium-Ion ones. The latter ones are preferable as they have high energy density and operate longer between charges. Lawn mower batteries are also divided into fixed and removable ones. Secondly, look at the unit's power ratings. Lawn mowers equipped with motors that have power ratings 40 volts and more are powerful enough and can be compared to gas-powered ones.

Consider the width of the cutting deck that ranges from 14 to 20 inches and more. The cutting deck width shows how big of an area the machine can cut at a time. For medium-sized lawns, 16-inch units would work fine while 20-inch mowers would be the best choice for larger yards. Since this feature affects the product price, we do not recommend simply following the rule: “bigger is better”, without taking into account the size of your lawn. We believe that the Greenworks 16-Inch 40V Cordless Lawn Mower meets these criteria best.

What Are the Advantages of Battery-Powered Lawn Mowers?

  • Rechargeable Battery. Most modern battery-powered lawn mowers come with rechargeable batteries. Having a rechargeable battery saves you from buying fuel. It also saves from needing to replace the battery every time you run the battery down. Lithium-ion batteries are more powerful and long-lasting.

  • No Fossil Fuel Use. As noted above, using a rechargeable battery means you can continuously refill your power source without needing to purchase an additional fuel source to keep it running. The battery-operated lawn mower does not use any kind of fissile fuels to keep it running smoothly for years.
  • Low Maintenance. The battery-powered lawn mower requires less maintenance than the more traditional gasoline option. Because it is battery powered and not gasoline-powered, you will not need to change spark plugs, fuel filters, or do routine oil changes. You only need to remember to charge the battery after you finish mowing the lawn.

  • Quieter. A battery-operated lawn mower is a lot quieter than a corded one. The gasoline-powered option needs additional components to make it run. All of these extras, like fuel filters, required pipes and sensors to ensure the safety of the device. They also make it louder. A battery-powered option does not have these extras, which makes it a lot quieter to run.
  • Emission-Free. Using battery power to run your lawnmower makes them a lot more energy-efficient and reduces the number of pollutants released into the environment. Battery power is emission-free, and you do not have to worry about polluting the environment as the battery will last for years before you need to replace it or turn them in.

13 Best-Selling Battery-Powered Lawn Mowers Comparative Table

What Are the Types of Battery-Powered Lawn Mowers and Their Differences?

  • Lead-Acid Battery. The lead-acid battery is older than other types of more modern batteries, but they still have benefits that the newer ones do not. They charge quickly and do not retain the memory from the previous charges so they can recharge quickly and return to standard power releasing. They produce high voltages, and between manufacturers, there is little difference aside from the date of manufacturing.
  • Lithium-Ion Battery. Lithium-ion batteries are still new to the world of batteries. They last longer than the older lead-acid batteries and are more powerful even when they are not full of power. They require more careful maintenance to prevent them from overheating and damaging the lawn mower.

Lithium-ion batteries are superior for longevity, but they also require more attention and keep them operating at best. Depending on the manufacturer and the limits on capacity, you can have a lithium-ion battery last up to twenty-five years compared with the lead-acid batteries, which have a maximum of five to seven years, depending on the manufacturer.
