Buyer’s Guide: All You Need To Know About The Best Lawn Mower Batteries

How Many Volts Should A Lawn Mower Battery Have?

How To Choose The Best Lawn Mower Battery

There are many characteristics to pay attention to while looking for different models.

Terminal Position And Cracking AMPS

Terminal position and cranking amps should be considered. Terminal positions are in different places, depending on the model, and it will make it impossible to fit the battery if it’s not the right one.

Famous Companies

Searching for well-known companies could help in your choice. Popular manufacturers which have long traditions try to keep the quality of their products so you can rely on them.

Battery Life

This is an important factor, depending on your garden. Getting stronger models with high performance will help you finish the job faster, and not spending much time on chagrining.

Working Temperature


Consider also on which temperatures the machine will work. It will be important if you are coming from areas with drastic temperature changes and extreme temperatures, which could impact the durability and performance. Simply check with yourself what is it that you need, and based on that search for the features which will help you do the best job.

Best Lawn Mower Battery Types

There are four major ones used for recharging:


Lithium-ion has already been listed since it is one of the most popular types. They are found in many devices because they are light-weight and have a high energy density, little or no memory effect and low self-discharge compared to other battery types. This is one of the reasons why they are the main choice for many customers.


Lead-Acid ones are a low-cost, reliable source of power. They are large and quite heavy, so they can’t be easily transported. However, these batteries have strong power, and that’s the reason they are still in use.


They are excellent at maintaining voltage and holding a charge when not in use. But they could fall under lazy battery effect when they are not fully charged. It means they lose their maximum capacity if they are constantly recharged, while not being fully discharged.

Nickel-Metal Hydride(NI-MH)

Compared to rechargeable nickel-cadmium, nickel-metal hydride have a higher energy density per volume and weight, making them a stronger and better choice than Ni-Cd.
