What Symptoms Indicate That Your Lawn Mower Battery May Need Replacement?
The symptoms indicating that your lawn mower battery may need replacement include slow cranking, the inability to start, corrosion, and battery leakage.
- Slow cranking sounds when starting
- Inability to start the mower
- Visible corrosion on battery terminals
- Battery leakage or swelling
- Electrical components malfunctioning
Recognizing these symptoms can help in maintaining your lawn mower’s performance and prolonging its lifespan.
-
Slow cranking sounds when starting:
Slow cranking sounds when starting signal that the battery may not be providing enough power. This symptom indicates that the battery is losing its ability to hold a charge. According to a study by the Battery Council International, a battery’s ability to crank reduces over time due to wear and tear. A cranking sound that lags could mean the battery voltage is below recommended levels, resulting in poor engine performance. -
Inability to start the mower:
The inability to start the mower directly suggests a dead or dying battery. If the mower fails to respond after multiple attempts, it is likely that the battery has reached the end of its life cycle. Research from Consumer Reports suggests that batteries typically last 3 to 5 years. If yours has reached this age and shows this symptom, it may need replacement. -
Visible corrosion on battery terminals:
Visible corrosion on battery terminals indicates chemical reactions that happen when a battery ages or has poor connections. Corrosion is often a blue or white powdery substance that builds up on terminals. The University of Nebraska-Lincoln Extension notes that such corrosion can create resistance, which prevents the battery from transferring power effectively. Cleaning the terminals can temporarily alleviate the problem, but significant buildup may indicate the need for a new battery. -
Battery leakage or swelling:
Battery leakage or swelling signifies internal damage. Leaks can be harmful to the mower and indicate that chemicals within the battery are escaping. The American Battery Manufacturing Association states that leaking batteries must be replaced immediately to avoid safety hazards. Swelling often means the battery is overcharged or defective, requiring prompt attention. -
Electrical components malfunctioning:
Malfunctioning electrical components such as lights or ignition switches can be signs of a failing battery. If the mower’s electrical parts show signs of sporadic function or fail to work, it may mean the battery is not delivering sufficient power. According to a 2021 study from the National Renewable Energy Laboratory, batteries that struggle to supply power can negatively affect the efficiency of other components, leading to bigger issues.
Replacing the lawn mower battery when these symptoms emerge will help maintain the mower’s efficiency and reliability.
