Safety and Usage Guidelines:

While lithium-ion batteries are known for their efficiency and durability, following safety precautions 

is vital to maximize their lifespan and ensure safe operation. We recommend the following guidelines:

Charging: Always use a charger specifically designed for lithium-ion batteries. Overcharging can 

shorten the battery's lifespan and pose safety risks.

Storage: Store the battery in a cool, dry place away from direct sunlight and heat sources. For 

long-term storage, it is recommended to charge the battery to about 40-60% capacity and check it 

periodically to ensure it has not fallen below its minimum voltage.

Handling: Avoid physical damage to the battery, such as puncturing, crushing, or bending, as this can

cause internal short circuits and lead to battery failure or fire.

Disposal: Lithium-ion batteries should be disposed of responsibly through a recycling program. 

Do not dispose of them in regular trash or incinerate them.
