Battery Swelling or Bulging: Battery swelling or bulging represents a critical failure. This phenomenon occurs due to overcharging or excessive heat generation within the battery. A swollen battery can leak harmful chemicals, representing a safety hazard. A report by the Consumer Product Safety Commission (CPSC) highlights that dealing with a bulging battery poses risks and necessitates immediate action.
-
Shortened Runtime During Mowing: A shortened runtime can indicate the battery is not holding a charge properly. If your mower dies quickly while in use, this may mean the battery’s capacity has been compromised. A capacity test by the Battery University in 2019 showed that a healthy battery should maintain charge for several hours under normal use.
-
Unusual Smells or Leaks: Unusual smells or leaks, such as a rotten egg odor, signal a serious battery issue. This smell often originates from sulfuric acid leaking or escaping gas from a malfunctioning battery. The National Fire Protection Association (NFPA) states that if you notice these symptoms, you should stop using the equipment immediately and consult a professional.
