What’s the Best Lawn Mower Battery for Me? 

A well-kept lawn doesn’t just happen by itself. It’s crucial to have a well-made lawn mower to help you ensure your yard looks top-notch. However, to get the most out of your lawn mower you need a long-lasting lawn mower battery.  
Lawn mower batteries typically range in price from $30 to over $200. The best one will coincide with the type of battery powered lawnmowers that you prefer or own.

What is the best battery for your lawn mower? 

The best lawn mower battery for your lawn mower or tractor will depend on a few factors:  

  • The lawn mower you have – Lawn mower batteries are ideal for battery operated lawn mowers and cordless electric lawn mowers. However, you might specifically be interested in a ride-on mower, lawn tractor, or walk mower. Knowing the type of mower you’re looking for can help you decide the type of lawn mower battery you need.  
  • Voltage – The type of lawn mower and how often you need it will also determine the type of battery voltage you need. For example, a lawn tractor might require 12 volts, whereas a more intensive lawn mower may require even more voltage. 
  • How it performs in weather – Batteries have a CCA rating, the number of amps a battery produces in 30 seconds in cold weather. A high rating is ideal.  
  • Lawn mower fit – Electric lawn mowers that are cordless and other types of battery operated lawn mowers typically house two types of batteries: U1L and U1R. They represent positions for + and – parts of the terminal. It’s important to find a battery that can fit either type.  

Understanding these elements can help you select the best battery for your lawn mower.
