A6： LiFePO4 batteries usually do not leak during normal use and proper handling. The main reasons are as follows: 1) Closed design:LiFePO4 batteries usually adopt a closed design, and the internal chemicals are sealed in the battery casing and will not come into direct contact with the environment. This prevents harmful substances in the battery from leaking or spilling. 2) High stability: LiFePO4 batteries have good chemical stability and will not produce volatile organic compounds or harmful gases during normal use. This reduces the battery’s negative impact on the environment.
