  • Please refrain from immersing the battery in water.
  • Ensure correct polarity when inserting batteries; align the (+) and (-) properly.
  • Avoid disassembly, disposal in fire, exposure to heat, or short-circuiting.
  • Limit battery exposure to prolonged sunlight.
  • Avoid mixing new batteries with used ones.
  • Keep batteries out of reach of children.


Cells must be packed in boxes with a charge of 30% to 50% State of Charge (SOC). During transportation, protect them from excessive vibration, shock, pressure, sunlight, and rain.


For storage (beyond 1 month), keep cells indoors in a dry, clean environment at temperatures between 0°C and 35°C. Charge and discharge them every 6 months, maintaining SOC between 30% and 50%.



1. Monitor and protect cell voltage, current, and temperature during charge and discharge.

2. Keep cells away from heat sources, open flames, strong acids, strong alkalis, or corrosive environments.

3. Never short-circuit or install batteries with incorrect polarity.

4. Avoid mixing cells from different models or manufacturers.

5. Do not subject cells to falls, impacts, punctures, disassembly, or structural alterations.

6. Maintain the battery charge between 30% and 50% SOC, and store it away from direct sunlight, high temperatures, and humidity for extended periods.

7. Wear protective gear, like rubber gloves, when handling batteries.

8. Immediately cease use in case of leakage, smoke, or cell damage, and contact our company for assistance.
