Lawn Mower Battery Buying Guide

Best Lawn Mower Battery

Now that we have discussed the top-rated batteries in the business, it’s time for us to discuss some important things that you need to consider before spending your hard-earned money on a lawnmower battery. In fact, these factors will ensure a good quality battery.

The factors that you should consider before buying a battery for your lawn mower are as follows:

Cold Cranking Amps (CCA)

CCA or cold cranking amps refers to the battery’s ability to start the engine of a lawnmower in cold temperatures. The CCA rating of the battery suited with a lawn mower is calculated using the number of Amps it can deliver at a temperature of 0 degrees Celsius.  

Typically, the CCA rating of a battery of the lawnmower ranges from 300A to 400A. But we suggest you buy a battery with a CCA rating of at least 320A. 

Battery Capacity

The capacity of a battery refers to the measurement of the amount of charge a battery can store. This capacity of a battery is represented with the Ah (Ampere Hour). 

The capacity of a lawnmower battery can range from 2.5Ah to 35Ah. Hence you have to check the instruction manual of your lawnmower to figure out what kind of such capacity your lawnmower needs. 


The battery’s overall performance completely depends on the quality of the materials that are used to make the battery. Most of the batteries that we have discussed in this article are SLA (Sealed Lead Acid) batteries. 

This type of batteries uses lead and lead dioxide as their active materials. And the battery’s plate is submerged in sulfuric acid. The lead in the battery’s plate reacts with the sulfuric acid and creates energy. 

You know the purity of the lead is essential. The battery will perform well only if the lead has a high level of purity. 


The outer casing of the battery protects it from receiving any kind of damage. So the casing needs to be durable in order to keep your battery safe. 

You should buy a battery that has a metal casing. Usually, aluminum is used for making the case of the battery. The casing also seals the battery and makes it spill-proof. 


You have to make sure that the voltage of the battery matches the voltage requirements of your lawnmower. You should check the instruction manual of your mower or call the customer service in order to find the voltage that’s required by your mower. 

Typically, the voltage of a battery of the lawn mower ranges from 12V-40V.
