– Keep batteries at least 2 meters away from heat sources.
5. The batteries in storage must be disconnected from external devices. The
indicators (if any) on the batteries should be o.
6. AC mains input voltage requirements in the recharge places: single-phase
power grid: 220 V/230 V/240 V, ±10%; three-phase voltage: 380 V/400 V,
±10%.
7. The warehouse keeper should collect battery storage information every
month and periodically report the battery inventory information to the
planning department. The batteries that have been stored for nearly 15
months (-10–25°C), 9 months (25–35°C) or 6 months (35–55°C) should be
recharged in a timely manner
8. Batteries should be delivered based on the "rst in, rst out" rule.
9. After the battery production test is complete and before the batteries are
stored, the batteries must be recharged to at least 50% of the SOC.
Conditions for Judging Overdue Storage
It is recommended that batteries not be stored for a long period. They should be
used soon after being deployed onsite. The batteries should be handled according
to the following requirements.

55°C < T Not allowed
1. Dispose of deformed, damaged, or leaking batteries directly irrespective of
how long they have been stored.
2. The storage duration starts from the latest charge time labeled on the battery
package. If a battery is qualied after recharge, update the latest charge time
and the next recharge time (next recharge time = latest charge time +
recharge interval) on the label.
3. Batteries can be charged for a maximum of three times during storage.
Dispose of batteries if the maximum charge times are exceeded.
