IV. Notes for Use

• Please use a matching 3.7V lithium battery charger for charging. Avoid using incompatible chargers to prevent battery damage or potential safety issues caused by overcharging.
• Do not place the battery in high temperature, fire source, direct sunlight, water or humid environment to avoid short circuit, bulging or leakage of the battery.
• Do not disassemble, pierce or squeeze the battery at will to avoid damaging the cells and causing potential safety hazards.
• When the battery is idle, it is recommended to keep 50%-70% power, store it in a cool and dry place, and supplement power regularly to avoid failure to activate the battery due to over-discharge.
• Please dispose of waste batteries in accordance with relevant environmental protection regulations. Do not discard them at will to avoid environmental pollution.
