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 stored according to
the following requirements.

Remarks
–10°C < T ≤
+55°C
T ≤ –10°C Not allowed Within the
recommended
storage duration:
Use the batteries
as soon as
possible.
Reaching the time
for recharge:
Recharge the
batteries.
The total storage
duration should
not exceed the
warranty period.
–10°C < T ≤ +25°C 15 months
25°C < T ≤ 35°C 9 months
35°C < T ≤ 55°C 6 months
T > 55°C 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
on the label (next recharge time = latest charge time + recharge interval).
3. The longest power storage period of a battery is three years. A battery can be
recharged at most for three times within the three years. For example, it can
be recharged every 8 months or every 12 months. It is recommended that
batteries be scrapped if the longest storage period and maximum recharging
times are exceeded.
4. If a lithium battery is stored for a long time, capacity loss may occur. After a
lithium battery is stored for 12 months at the recommended storage
temperature, the irreversible capacity loss rate is 3%–10%. If customers
perform a discharge test according to the
specications for batteries stored
for too long, they may fail to pass the test.
Inspection Before Recharge
1. Before recharging a battery, you need to check its appearance. Recharge the
battery if it is
qualied or dispose of it if not.
2. The battery is qualied if it is free from the following symptoms:
– Deformation
