3.4. Storage
3.4.1 Battery storage conditions :
Batteries should be stored at low temperature (-15-40 ＜ C) dry clean room, to avoid direct sunlight.
Batteries placed in the process, the loss of capacity due to self-discharge, a discharge capacity than its rated capacity low, After 2-3 months after the general charge-discharge cycles can reach its rated capacity.
When cells do not have long-term placement, to be periodically added to the battery -- and its supplement cycle -- see (table).

3.4.2 Battery storage time and temperature relationship
When the battery self-discharge means of storage batteries, the electrochemical reaction due to the loss of internal capacity its self-discharge rate and battery temperature is still unknown.

3.4.3Battery storage time and temperature relationship
When the battery self-discharge means of storage batteries, the electrochemical reaction due to the loss of internal capacity its self-discharge rate and battery temperature is still unknown.

3.4.4 Open circuit voltage and remaining battery capacity :
By measuring open circuit voltage of the battery can also determine the remaining capacity.
