Battery storage

1. Battery storage environment:

Batteries should be stored in a 15 ℃ to 40 ℃ dry clean room, avoid direct sunlight.

Battery in the process, due to the discharge capacity, the first put the capacitance will be lower than the rated capacity, generally by 2-3 charging loop to its rated capacity.

When the battery is not in use for a long, need to complement battery regularly, the supplementary electrical cycle to see the table below.

Storage temperature	Added a little ore time
below20℃(65℉)	12 months
20-30℃(68-86℉)	6 months
30-40℃(86-104℉)	3 months

2. the relationship between storage time and temperature of battery
The self discharge of a battery is the loss of capacity due to the electrochemical reaction when the battery is placed open. The rate of self discharge has a great relationship with the temperature of the battery. Figure 6 shows the relationship between the storage time and the temperature of the battery.

3. The relationship between the residual capacity of battery open circuit voltage and:
By measuring the open circuit voltage of the battery can also determine the residual capacity, figure 7 for the remainder of the battery capacity and the relationship between the open circuit voltage curve.

1.2. Constant current charging:
When using the method of the battery, charging power supply is cut off a full battery note must be immediately, otherwise it will cause the battery charging, and damage to the battery performance and life, with constant current charging, the battery discharge when the charge capacity reached last 1.1 ~ 1.4 times, it shows that the battery has enough power.
