Can a lithium battery still be used after being stored for three years?
1 Answers
Whether a lithium battery can still be used after being stored for three years mainly depends on whether it has been properly maintained during storage. If well-maintained, it can still be used. The ideal voltage for long-term storage of lithium batteries is 3.6-3.8V, so it is recommended to check at least twice a year and perform two charging maintenance sessions. High-quality lithium batteries may not be damaged even after three years of storage due to self-discharge, while low-quality lithium batteries with high self-discharge rates may get damaged over time. Below are some methods for properly maintaining a car battery: 1. Regularly clean the battery: Pay attention to the battery's condition during daily use. Over time, the battery may accumulate dust, powder, oil stains, etc. To ensure normal operation, promptly clean the battery's panel and the dirt on the positive and negative terminals to extend its lifespan. 2. Avoid prolonged parking: If the vehicle is left unused for a long time, the battery will self-discharge. Therefore, even if the car is not used regularly, it is recommended to start it once a week and take it for a short drive to keep the battery fully charged. 3. Regular inspection: The typical lifespan of a car battery is 3-4 years. For high-end models with more electronic systems, the battery's lifespan may be shorter. Regular inspections of the battery's charge retention can help maintain it in optimal working condition.
