Storage Guidelines
The battery should be stored in a clean, dry, and well-ventilated room at temperatures between -5℃ to 35℃. Keep away from fire, heat sources, and corrosive elements.
Batteries must be charged every 3 months during storage. Follow the "first come, first use" principle for both stored cells and batteries in delivery.
The battery storage period is 24 months from warehouse entry. Batteries exceeding this period require thorough inspection. Only applicable batteries can be dispatched to purchasers; non-applicable units must be rechecked, with the purchaser retaining rights to dispose of defective units.
