Quick Answer
SIGNs OF LITHIUM BATTERY END-OF-LIFE include reduced capacity, increased self-discharge, and noticeable swelling or bulging of the battery casing.
Symptoms of End-of-Life Lithium Batteries
Lithium-ion batteries have a limited lifespan, with most manufacturers recommending replacement after 3-5 years. One of the earliest signs of end-of-life is a noticeable reduction in capacity. This can be measured by comparing the battery’s original and current charge capacity. For example, if a battery was originally rated at 10Ah and now only holds 7Ah, it may be nearing the end of its lifespan.
Visual Inspection for Swelling or Bulging
Regular visual inspections can help identify potential issues with lithium-ion batteries. Check the battery casing for any signs of swelling, bulging, or warping. Any noticeable change in shape can indicate internal damage and increased risk of overheating or fire. If a battery is showing signs of swelling, it should be removed from service immediately and properly disposed of.
Safe Disposal and Replacement
Proper disposal of lithium-ion batteries is crucial to prevent fires and environmental contamination. When disposing of a lithium battery, ensure it is in a sealed container and handled carefully to prevent short-circuits. To replace an end-of-life lithium battery, purchase a new unit from a reputable manufacturer and follow proper installation procedures.
