How To Choose the Best Replacement Mower Battery?

Selecting a replacement battery for your John Deere tractor, mower, or other equipment requires a few key pieces of information:

Make and model of your John Deere vehicle

This lets you pinpoint the correct battery for your specific model in the size chart. (Read Michelin Wiper Blade Size Chart)

Battery group size

Batteries are commonly categorized by group size, which refers to the battery’s physical dimensions. Group sizes like 24M or 34/78 are standard across brands.


Most John Deere batteries are 12V, but always check your owner’s manual. Voltage must match.

CCA rating

The Cold Cranking Amps (CCA) indicate how much power the battery can provide to start your engine in cold weather. A higher CCA rating is better.

Reserve capacity

This specifies how long the battery can run electronics/accessories when the vehicle is off. Higher is better. Once you have this crucial information, you can use the John Deere battery size chart to zero in on the optimal replacement battery for your equipment.

Why Do You Need a John Deere Tractor Battery Size Chart?

With many battery options and specifications, a battery size chart is invaluable when selecting a replacement. Here are some key reasons you need a size chart:

  • Takes the guesswork out: Rather than trying to eyeball battery dimensions or guess at the right CCAs, the chart tells you exactly the right battery you need.
  • Ensures fit: The size chart provides the precise group size and different sizes of battery for your John Deere model.
  • Confirms technical specs: You can match up the voltage, different types of battery output, CCAs, reserve capacity, and other specs to choose the best battery for your vehicle.

Using Group Size to Select a Battery

Identifying the correct group size is crucial for choosing a replacement battery. This refers to the battery’s physical dimensions, commonly expressed in a code like 24M or 34/78S. 

Group size is standardized across brands, so you can shop multiple options knowing they will fit the specific battery tray in your John Deere vehicle. Referencing the group size ensures your new battery has the appropriate:

  • Length
  • Width 
  • Height
  • Terminal configuration

Battery Specs to Cross-Reference

In addition to the correct group size, you’ll also want to match other key battery specifications:


Almost all John Deere equipment uses a 12-volt battery. Just verify the voltage required for your particular model.

CCA Rating

  • The Cold Cranking Amps (CCA) indicate how much power the battery can supply to start your engine in cold temperatures.
  • Look for a battery that equals or exceeds your John Deere’s recommended CCA rating for reliable starting power.
  • Batteries with higher CCAs provide extra starting power.

Reserve Capacity 

The reserve capacity tells you how long the battery can run accessories with the engine off.

Look for a battery that meets or exceeds your John Deere’s required reserve capacity.

More reserve capacity means longer runtime for electronics and accessories before a recharge is needed. (Read Trimmer Line Sizes Chart)

Battery Posts

  • John Deere batteries typically have standard SAE top automotive posts.
  • Some models use batteries with bolt-on terminal connectors.
  • Match the positive terminal style of your original battery.
  • Cross-referencing these specifications ensures your new battery has the starting power, runtime, and connections to fit and function in your John Deere equipment properly.

  • Recharge after each use to avoid deep discharge
  • Store equipment in a cool area to reduce self-discharge over a period of time 
  • Clean battery terminals regularly to avoid corrosion issues during extended storage
  • Avoid draining the battery below 50% charge if possible
  • Check battery voltage monthly and recharge as needed
  • Consider a deep cycle battery tender to maintain optimal charge

Following basic battery care and maintenance best practices will ensure you get the longest life from your new battery.

John Deere Battery Warranties

Replacement John Deere batteries come with warranties up to:
