  How to determine if a lithium battery has aged?

  1. Observe the appearance of the battery: Check for signs of expansion, deformation, or leakage. These may be pressure changes caused by internal chemical reactions in the battery, indicating that the battery may have aged.

  2. Testing battery performance: Use professional battery testing instruments to measure the charging capacity, discharging capacity, and internal resistance of the battery. If the actual capacity of the battery drops below 80% of its nominal capacity, it usually means that the battery has significantly aged.

  3. Observing usage time: If the battery's usage time is significantly shortened, or the battery's endurance performance decreases significantly under the same usage conditions, this may be a sign of battery aging.

  4. Pay attention to battery safety performance: Check whether the battery has safety hazards such as overheating, leakage, or short circuit, which are signals that the battery may need to be replaced.

  5. Use a multimeter to test: If you have a multimeter, you can determine the health status of the battery by testing the voltage drop of the battery under load. If the voltage drop is significant under load, it may indicate a decrease in the battery's carrying capacity, i.e. battery aging.

  6. Consider the lifespan and maintenance of batteries: Understand the expected lifespan of batteries and determine whether replacement is necessary based on usage habits and maintenance measures. Good usage habits and proper maintenance can extend the lifespan of batteries.

  7. Consider replacing the battery or device: If the battery shows obvious signs of aging, it should be considered to replace the battery or device to ensure its normal operation and safe use.
