● If the storage temperature ranges from 40°C to 60°C, the storage period shall
be less than two months. If the storage period exceeds two months, check the
battery status and place the battery modules in an environment with a
temperature ranging from 0°C to 40°C.
● Relative humidity: ≤ 95% RH
● The packing cases of battery modules must be intact.
● Do not unpack batteries. If charging is necessary, they must be charged by
professionals as required and then returned to their original packaging after
charging.
● The warehouse keeper shall collect battery storage information every month
and periodically report the battery inventory information. The batteries in
long-term storage shall be charged in a timely manner.
● Ensure that batteries are delivered based on the "rst in, rst out" rule.
● If batteries have been stored for longer than allowed, promptly report the
event to the person in charge.
4.4 Battery Module Storage Duration and Recharge
Requirements
A longer storage duration results in larger battery capacity attenuation. Recharge
the battery module after it is stored for a period of time. Determine whether to
recharge or scrap a battery module by referring to Table 4-1.
Table 4-1 Battery module storage duration and recharge requirements
Storage Duration
(Months)

Requirement
Note
0–9 No action is
required. Use the
battery module as
soon as possible.
NOTICE
● If the ambient temperature for storage
is 0°C to 40°C and the last recharge
time has elapsed for 0 to 12 months,
the irreversible attenuation of the
battery capacity is about 3% to 10%.
● The interval between two recharges
cannot exceed 12 months.
9–12 Recharge it for
the rst time.
18–24 Recharge it for
the second time.
27–36 Recharge it for
the third time.
12 months after
the third recharge
It is advisable to
scrap the battery
module.
