Understanding John Deere Battery Types
John Deere uses a variety of battery group sizes depending on the equipment. The most common categories include:
1. U1 and U1R Batteries
These are the most common batteries used in John Deere riding mowers and lawn tractors.
- U1 has the positive terminal on the left.
- U1R has the positive terminal on the right.
These batteries are compact, lightweight, and provide enough CCA for small engines.
2. Automotive-Style Batteries (Group 24, 24F, 26, 35, 48, 49)
Larger John Deere tractors and Gators often use automotive-style batteries.
These provide stronger starting power and higher CCA ratings suitable for:
- Utility tractors
- Compact tractors
- Commercial ZTRs
- Gators
- Construction equipment
3. Group 31 Heavy-Duty Batteries
For the biggest John Deere equipment, Group 31 batteries are used.
These offer:
- Very high CCA
- Strong reserve capacity
- Support for diesel powertrains
Common in:
- Large tractors
- Skid steers
- Construction machines

How to Choose the Right Battery for Your John Deere Equipment
Choosing the right replacement battery involves checking the following:
1. OEM Part Number
This is the safest way to ensure compatibility. If your battery label shows a part like TY25878 or MIA10325, cross-reference it with the table above.
2. Battery Group Size
The group size determines:
- Terminal placement
- Dimensions
- Fitment
- Cable reach
Never buy a battery that doesn’t match your equipment’s group size.
3. Voltage
Nearly all John Deere equipment uses 12-volt batteries. Older or vintage tractors may use 6-volt, but these are rare.
4. CCA Rating
Cold cranking amps determine starting power.
Typical CCA needs:
- Lawn mowers: 250–350 CCA
- Gators: 350–500 CCA
- Small tractors: 500–700 CCA
- Heavy machinery: 700–900+ CCA
5. Terminal Orientation
John Deere uses both left-hand and right-hand positive terminals. Match it exactly to avoid cable alignment issues.

Signs Your John Deere Battery Needs Replacement
Watch for these signs before your battery dies completely:
1. Slow Engine Cranking
If your engine turns over sluggishly, especially in cold weather, the battery is weakening.
2. Clicking Sound on Start
Rapid clicking indicates the solenoid isn’t receiving enough power.
3. Corroded or Swollen Battery Case
Heat, age, or acid leakage can damage the battery.
4. Battery Won’t Hold a Charge
If your battery drains quickly even after charging, the cells may be failing.
5. Equipment Electrical Problems
Dim lights, weak accessories, or fluctuating power often point to battery issues.

How to Make Your John Deere Battery Last Longer
Here are expert tips to extend battery life:
1. Keep Terminals Clean
Dirty or corroded terminals reduce power transfer. Clean them with a wire brush and apply dielectric grease.
2. Use a Smart Charger in Off-Season
For winter storage, use a trickle or battery maintainer to prevent sulfation.
3. Avoid Deep Discharges
Most John Deere batteries are starting batteries, not deep-cycle. Avoid running them down completely.
4. Store in a Cool, Dry Place
Heat shortens battery life significantly.
5. Check Charging System
A faulty alternator or voltage regulator may drain your battery faster.

FAQs
What size battery does a John Deere tractor use?
John Deere tractors use a wide range of battery sizes depending on the model. Smaller lawn tractors typically use U1 or U1R batteries, while compact utility tractors often use Group 24, 24F, 26, or 35. Larger agricultural tractors and construction equipment generally use Group 31, 31P, 31A, or 49 batteries. The exact battery size depends on engine size, electrical demand, and starting requirements.
What is the difference between a U1 and a U1L battery?
The main difference between a U1 and U1L (or U1R) battery is terminal orientation.
- U1 has the positive terminal on the left.
- U1L or U1R has the positive terminal on the right.
- Both batteries are the same physical size and are commonly used in lawn tractors, but choosing the wrong terminal orientation can prevent the cables from reaching properly.
Are group 24 and 34 batteries the same size?
No, Group 24 and Group 34 batteries are not the same size.
- Group 24 batteries are taller and slightly longer.
- Group 34 batteries are shorter and more compact, but often have higher CCA ratings.
- Because of these differences, they are not direct drop-in replacements unless the battery tray is adaptable.
What battery is the same size as a 96R?
A Group 96R battery is very similar in length and width to a Group 47 (H5) or Group 48 (H6), but it has a slightly different height and terminal configuration. While the physical size is close, the terminal placement and electrical specs require verifying compatibility before substituting a 96R with another group.
How do I know my battery size?
You can determine your battery size by checking:
- The label on your current battery, which lists the group size.
- Your John Deere owner’s manual, which specifies the correct battery model.
- Your equipment’s battery tray, which dictates the maximum length, width, and height.
- OEM part numbers, which can be cross-referenced with battery group sizes using a chart like the one provided earlier.
What size battery do I need for a tractor?
The battery size you need depends on the type of tractor.
- Lawn tractors: U1 or U1R (approx. 300–350 CCA)
- Gators and compact tractors: Group 24, 24F, 26, 35, 34, 48 (500–750 CCA)
- Utility and large ag tractors: Group 31, 31P, 31A, 49 (700–1000+ CCA)
Always match the group size, voltage, CCA rating, and terminal orientation to your John Deere model specifications.
Final Thoughts
The right battery ensures your John Deere mower or tractor starts every time and delivers reliable performance. With the comprehensive John Deere battery cross-reference chart provided above, you can now easily match any OEM battery number with its correct group size and replacement equivalent.
Whether you own a residential lawn tractor or manage a fleet of commercial and agricultural equipment, choosing the correct battery saves time, protects your electrical system, and keeps your Deere working at its best.
