STORAGE
● Batteries should be stored in dry and clean warehouse which has good air exchange system. Batteries should avoid direct sunlight. Batteries should not be near to heat (such as radiator, the distance should more than1m). Batteries should avoid any toxic gas and organic solvent.
● When the ambient temperature is less than 25℃, the longest storage life is 6 months. If ambient temperature is higher, the longest storage life varies as specified in below chart.

Storage Temperature (℃) ≤25 26~33 34~40
Storage Time (Month) 6 3 1

 
 
 
 
● Batteries should be recharged within the storage life or before using.
Charging methods: maximum charging current 8A, constant voltage 2.45±0.05V/cell (25℃);
Charging time: 15~20h; Temperature compensation coefficient: -5mV/℃/cell.
 
OPERATION
 
Equalizing Charge
1 Equalizing Charging Occasion

It is unnecessary to equalizing charge the battery in normal operation. But if the float voltage is set too low, or it is affected by environment temperature so that the consistency of batteries in battery group is very bad, then equalizing charge should be adopted when the following conditions happen:

  1. After 3 months’ float charging operation and the there are more than 2 pieces batteries which voltage is less than 13.08V;
  2. The voltage difference of each battery reaches +/-0.48V in float charging operation; the voltage difference of each battery reaches +/-0.30V after 12 months float charging 12 months.

2 Equalizing Charging Methods
Using limiting current (0.30C20 (A)) and constant voltage charging.

Charging Voltage(V/piece) Time of Charging(h)
Working Environment Temperature13-20℃ Working Environment Temperature21-32℃
14.0 48 24
14.4 24 12

 
 
Cycle Operation
Cycle operation means to charge and discharge battery periodically.
1 Discharge Current and Final Voltage
Discharge current bigger, final voltage lower. Below table shows the final voltage at the difference discharge current:

Charging Current(A) Final Voltage(V/piece)
0.1C20 10.5
0.5C20 10.2
3C20 9.6

2 Charging Current, Charging Voltage and Charging Time
Battery should be charged with limiting current and constant voltage when cycle charging. Setting a limiting current at 0.30C20 (A) and a limiting voltage, start charging with original current till the battery terminal voltage reaches the definite voltage and time. The set of float charging voltage is relevant with the temperature of the battery. When the temperature is between 21-26℃, the floating voltage is 13.65V/pcs. Adjust the floating voltage(-18.0V/℃/piece) when the temperature is above the range. If the ripple current of the charging equipment is accord with the recommendation of the Manual, use the daytime temperate as the floating charging temperature, otherwise use terminal temperature. The best floating voltage of the battery in different working environment temperature is suggested as following:

Working Environment Temperature (℃) Charging Voltage(V/pcs) Charging Time(h)
-5~4 14.8 24
5~10 14.7 24
11~15 14.6 20
16~20 14.5 20
21~26 14.4 20
27~32 14.3 16
33~38 14.2 16
39~44 14.1 16
45~50 14.0 16
