Nowadays, battery lawn mowers are becoming a new trend of lawn mowers due to the advanced features of them. If you would like to buy a new mower for your lawn to replace the old one, then this type of lawn mower should be one of your top considerations. In this article, I would like to show you an overview of the battery lawn mower, to provide you a clear overview of it. It may help if you are intending to buy the best battery lawn mower 2021 for your lawn.

Why do we need a battery lawn mower?


1. Quiet operation

If you have a chance to compare the electric cord lawn mower with a gas lawn mower, you will see the electric one is more quiet. I’m sure that this type of lawn mower will not cause as much noise as a gas lawn mower. A running gas mower can reach 90 decibels, but the experts recommended us to use the ear-protectors at 75 decibels. Meanwhile, a running electric mower only reaches about 65-85 decibels, depending on manufacturers. Therefore, using an electric lawn mower, you can protect yourself as well as avoid disturbing your neighbors!

2. Easy to use and maintain

The battery lawn mower has a simpler design. It needs less maintenance. You just have to clean it after each use and periodically sharpen its mowing blades. Besides that, it is lighter and easier to start, drive, and change direction. Just press the power button and go!

3. It’s an eco-friendly product

Your purpose when establishing a lawn may be to create a green environment to enhance the quality of life. Our beautiful garden will help us to get closer to nature. Therefore, an eco-friendly product should be our first choice! But, using a gas lawn mower can cause air pollution just like using the car and motorbike. On the contrary, operating an electric lawn mower can help you save nature and build a better environment for your house.

4. An economical option

The price of battery lawn mower may be a little bit higher than a gas lawn mower. However, if you consider the cost spending on fuel, then the electric lawn mower will win. In fact, the cost spending on electricity is much less than the cost spending on gas or oil. You can easily do the calculation with current gas and oil price. For a long-term use, the battery lawn mower is a better option.

How to choose a best battery lawn mower?

Each type of lawn mower has many different models based on four criteria: battery size, cutting width, features and whether it’s a self-propelled lawn mower or not. There are several things you should consider to choose the best mower for your lawn.

Battery capacity

The cell size will decide how long a battery lawn mower can work. Currently, there are three standard battery packs: 12 volts, 24 volts, and 36 volts. Their running times are respectively around: 30 – 45 minutes, 45 – 75 minutes, and 90 minutes. Depending on the size of your lawn, you can choose the right battery.

Moreover, please consider the battery type carefully. Just like using a cell phone, the battery type plays a major role in keeping your lawn mower in a good operating condition. Recommended battery types are lithium-ion or nickel-hydride.

Cutting width

The cutting widths should be one of the most important pieces of information you should check first when choosing a lawn mower. This factor effects the productivity and quality of the machine. Usually, the lawn mower cutting width varies from 20 to 24 inches. The longer the cutting width is, the more effective the lawn mower is.


Most of us like an all-in-one device ;therefore, buying a battery lawn mower with mulching, bagging or side/rear discharge function is a very good idea. However, please remember that each type of lawn mower has its pros and cons, and a battery lawn mower with the advanced features will have a higher price. So, make sure that you have a clear purpose when choosing it.

Self-propelled or not?

Some reviews said that most of the battery lawn mowers are not self-propelled lawn mowers. However, it does not mean that all available products on the market are not self-propelled. You can easily find a self-propelled one on the market. A lawn mower with a self-propelled function will help your mowing task become much easier because you will not try to push it. The price of a self-propelled lawn mower is usually more expensive than a push mower or reel mower.
