Maintaining your lawn mower battery in optimal condition is essential for ensuring reliable performance and extending its lifespan. Regular checks and maintenance can prevent unexpected failures and keep your lawn mower running smoothly. Here’s a comprehensive guide on how frequently you should check your lawn mower battery and how to perform these checks effectively.
Recommended Checking Frequency
During the Mowing Season (Spring to Fall)
During the active mowing season, it is crucial to monitor your lawn mower battery regularly. We recommend checking the battery at least once a month. This regular inspection helps ensure that the battery remains fully charged and performs efficiently. Frequent checks also allow you to catch any potential issues early, preventing disruptions during your mowing sessions.
During Winter Storage
When your lawn mower is not in use during the winter months, the battery still requires attention. During this period, it is advisable to check the battery at least once a week. Cold temperatures can affect battery performance and lead to quicker degradation if the battery is not maintained properly. Regular checks during winter help ensure the battery remains in good condition and is ready for use when the mowing season resumes.
How to Check Your Lawn Mower Battery
Using a Multimeter
To accurately assess the condition of your battery, you will need a multimeter. Follow these steps to measure the battery’s voltage:
- Set the Multimeter: Configure the multimeter to the 20V DC setting, which is suitable for measuring battery voltage.
- Connect the Probes: Attach the red probe to the positive (+) terminal of the battery and the black probe to the negative (-) terminal.
- Read the Voltage: A fully charged battery should display a voltage reading between 12.6 to 12.7 volts. If the voltage falls below 12.4 volts, the battery is partially discharged and may need recharging.
- Check for Discharge: A reading below 12.2 volts indicates a fully discharged battery, which likely requires immediate recharging or replacement.
Additional Inspection Tips
- After Mowing: It is beneficial to check the battery after each mowing session. The mower’s alternator charges the battery while in operation, and ensuring it is adequately charged can prevent future issues.
- Avoid Key Drainage: To prevent unnecessary battery drainage, always remove the key from the ignition when the mower is not in use. Leaving the key in the “on” position can slowly drain the battery.
- Clean Terminals Regularly: Inspect and clean the battery terminals to avoid corrosion. Corroded terminals can impede the battery’s performance and reduce its lifespan.
Signs of Battery Wear
Regular checks should also involve looking for physical signs of battery wear, including:
- Bulges or Cracks: Visible damage such as bulges or cracks indicates that the battery may be compromised and should be replaced.
- Difficulty Starting: If you experience slow engine starts or the mower struggles to turn over, these could be signs that the battery is nearing the end of its life.
When to Replace Your Battery
Typically, a lawn mower battery should be replaced every 3 to 5 years, depending on usage and maintenance. If you observe significant wear, difficulty starting the mower, or consistently low voltage readings, it may be time to invest in a new battery.
Conclusion
Regular maintenance of your lawn mower battery is crucial for optimal performance and longevity. By checking the battery monthly during the mowing season and weekly during winter storage, you can ensure your battery remains in top condition. Use a multimeter to monitor voltage levels, clean terminals regularly, and be attentive to signs of wear. Following these guidelines will help extend the life of your lawn mower battery and keep your mower operating smoothly.
