Common problems before use

• Inconsistent battery capacity: Due to the production process, the capacity of different batteries may vary to a certain extent, which will cause the battery pack to be unbalanced during use.
  

• Inconsistent internal resistance: The internal resistance of the battery will also vary, which will affect the charging and discharging efficiency and life of the battery.

• Poor consistency: The consistency of the battery refers to whether the performance parameters of each battery in the battery pack are consistent. Poor consistency will lead to a decline in the performance of the battery pack and even safety hazards.

Common problems during use

• Capacity decay: As the number of uses increases, the capacity of the battery will gradually decay. This is an unavoidable phenomenon for all batteries.

• Increased internal resistance: During the charging and discharging process of the battery, a certain amount of heat will be generated inside, which will cause the internal resistance of the battery to increase, thereby affecting the performance of the battery.

• Safety hazards: Although the safety of lithium iron phosphate batteries is relatively high, safety accidents may also occur under extreme conditions, such as overcharging, over-discharging, short circuit, etc.

• Environmental impact: Too high or too low temperature will affect the performance and life of the battery.

Common problems after use

• Scrap disposal: Improper disposal of waste batteries will pollute the environment. Therefore, the recycling and disposal of waste batteries is an important environmental issue.

• Battery recycling: The materials in lithium iron phosphate batteries can be recycled, but the current recycling technology is not mature enough and the recycling cost is high.
