Understanding the Role of the Battery in a Craftsman Riding Lawn Mower
Function of the Battery
The battery in a Craftsman riding lawn mower primarily provides the electrical power needed to start the engine. Once the engine is running, the alternator or charging system supplies power to keep the battery charged and to operate electrical components such as lights, gauges, and the ignition system.
Why a Reliable Battery Matters
A dependable battery ensures:
- Quick and reliable engine starts
- Smooth operation of electrical accessories
- Prevention of breakdowns during mowing sessions
- Avoidance of costly repairs caused by battery failure or improper voltage supply
Types of Batteries Suitable for Craftsman Riding Lawn Mowers
Choosing the right type of battery is crucial for optimal performance. Here are the common types used in riding mowers:
Sealed Lead Acid (SLA) Batteries
- Most common for lawn mowers due to affordability and reliability
- Maintenance-free; no need to add water
- Generally have a lifespan of 2-4 years
Absorbed Glass Mat (AGM) Batteries
- A subtype of SLA batteries with better vibration resistance and longer lifespan
- Offer higher cold-cranking amps (CCA), ideal for colder climates
- Maintenance-free and spill-proof
Lithium-Ion Batteries
- Emerging technology, less common in riding mowers
- Lightweight and longer-lasting
- More expensive and typically used in specialized equipment
Choosing the Right Craftsman Riding Lawn Mower Battery
Battery Specifications to Consider
When selecting a new battery, pay attention to:
- Group Size: Ensures the battery fits in the compartment
- Cold Cranking Amps (CCA): The ability to start the engine in cold weather
- Reserve Capacity (RC): How long the battery can supply power if the alternator fails
- Voltage: Most riding mower batteries are 12 volts
How to Find the Correct Battery
1. Consult the Owner’s Manual: The manual provides specific battery model numbers and specifications.
2. Check the Existing Battery: Note the group size and specifications printed on the battery label.
3. Use Online Resources: Websites and parts stores often have compatibility guides for Craftsman riding mowers.
4. Visit a Local Dealer or Repair Shop: Professionals can help recommend the right battery based on your mower model.
Installing a New Craftsman Riding Lawn Mower Battery
Tools Needed
- Socket wrench or pliers
- Battery terminal cleaner
- Safety gloves and goggles
Installation Steps
1. Ensure Safety: Turn off the mower and disconnect the spark plug to prevent accidental starting.
2. Locate the Battery Compartment: Usually under the seat or in the rear section.
3. Remove the Old Battery: Loosen the terminals (negative (-) first, then positive (+)), and carefully lift the battery out.
4. Clean Terminals and Connectors: Use a terminal cleaner to remove corrosion.
5. Place the New Battery: Ensure correct orientation, with terminals in the proper position.
6. Connect Terminals: Attach the positive (+) terminal first, then the negative (-).
7. Secure the Battery: Use the bracket or hold-down to prevent movement.
8. Test the Mower: Turn on the ignition to verify the starting system and electrical components work correctly.
Battery Maintenance and Care Tips
Proper maintenance can extend the life of your Craftsman riding mower battery. Here are essential tips:
Regular Inspection
- Check for corrosion around terminals and clean as needed
- Look for cracks, leaks, or swelling in the battery case
- Ensure terminals are tightly connected
Keep the Battery Charged
- Use a trickle charger if the mower will be stored for extended periods
- Avoid deep discharges; keep the battery charged above 50% when not in use
Maintain Cleanliness
- Clean the terminals with a mixture of baking soda and water to neutralize corrosion
- Apply a terminal protectant or petroleum jelly to prevent further corrosion
Store Properly During Off-Season

- Store in a cool, dry place away from direct sunlight
- Keep the battery charged during storage using a compatible charger
Troubleshooting Common Battery Issues
Even with proper care, batteries can encounter problems. Here are common issues and solutions:
Engine Won’t Start or Slow Crank
- Check the battery voltage with a multimeter (should be around 12.6V when fully charged)
- Inspect terminals for corrosion and clean if necessary
- Test the battery’s CCA; replace if below the recommended level
Electrical Components Not Functioning Properly
- Ensure the battery has sufficient charge
- Check fuses and wiring for damage
- Verify that the alternator or charging system is functioning correctly
Battery Dead or Swollen
- Indicates aging or internal damage
- Replace the battery promptly to prevent damage to the mower’s electrical system
