⚠️ IMPORTANT SAFETY NOTICE ⚠️ Lithium-ion batteries require proper handling and knowledge to ensure safe operation. Failure to follow safety guidelines may result in fire, explosion, serious injury, or property damage.

General Safety Guidelines:

•  Only purchase and use if you fully understand lithium-ion battery safety.

•  Always charge in or on a fire-resistant surface—never leave batteries charging unattended.

•  Use only a compatible smart charger designed specifically for 3.2V/3.65V lithium-ion cells.

•  Store batteries in a protective case—never carry them loose in a pocket, bag, or purse.

•  Keep away from metal objects (keys, coins, tools) to prevent short circuits.

•  Use only within manufacturer-listed specifications and in protected battery packs with a proper BMS.

•  Resellers must provide these warnings to all customers.

Prohibited Uses & Handling:

•  DO NOT use this battery in e-cigarettes, vaporizers, or similar devices.

•  DO NOT mix old and new, or used and unused batteries.

•  DO NOT short circuit, puncture, cut, crush, incinerate, or modify the battery.

•  DO NOT use if the battery wrapper is torn or damaged in any way.

•  DO NOT overcharge or over-discharge—this can lead to battery failure or venting.

•  DO NOT expose the battery to liquids, extreme heat, or direct sunlight.

•  DO NOT solder directly—only use spot welding or nickel strips for battery pack assembly.

•  DO NOT exceed 20A continuous discharge.
