Conditions for Determining Long-term Storage
Do not store batteries for extended periods of time. The deep discharge during
storage may damage batteries. If you have to store batteries, observe the
following storage requirements.

AC mains input voltage requirements on the charging facilities: single-phase
voltage: 220 V/230 V/240 V, ±10%; three-phase voltage: 380 V/400 V, ±10%.
The warehouse keeper shall collect battery storage information every month
and periodically report the battery inventory information to the planning
department to ensure that batteries are charged in a timely manner.
After the battery production test is complete and before the batteries are
stored, the batteries must be charged to at least 50% SOC.

Dispose of deformed, damaged, or leaking batteries directly irrespective of
how long they have been stored.
The storage duration starts from the latest charge time labeled on the battery
package. If a battery is qualified after charge, update the latest charge time
and the next charge time (Next charge time = Latest charge time + Charge
interval) on the label.
Batteries can be charged for a maximum of three times during storage.
Dispose of batteries if the maximum charge times are exceeded.
Long-term storage of lithium batteries will cause capacity loss. The longer the
storage duration, the greater the capacity loss. Batteries may fail the
