充电电压不得超过本标准书中规定的额定电压 8.3V（单颗 4.15V），8.4V（单颗 4.20V）为充电电压最高极限，
充电器设计应满足此条件：电芯电压高于额定电压值时，将可能引起电池的充放电性能、机械性能和安全性
能的问题，可能会导致发热或泄漏。
1.3 Charging temperature 充电温度:
The battery shall be charged within 10℃~45 range in the Product Specification.℃
电池必须在 10 ~45℃℃的环境温度范围内进行充电。
1.4 Prohibition of reverse charging 禁止反向充电:
Reverse charging is prohibited. The battery shall be connected correctly. The polarity has to be confirmed before
wiring, In case of the battery is connected improperly, the battery cannot be charged. Simultaneously, the reverse
charging may cause damaging to the battery which may lead to degradation of battery performance and damage the
battery safety, and could cause heatgeneration or leakage.
正确连接电池的正负极，严禁反向充电。若电池正负极接反，将无法对电池进行充电。同时，反向充电会降
低电池的充放电性能、安全性，并会导致发热、泄漏。
2. Discharging 放电
2.1 Discharging current 放电电流
The battery shall be discharged at less than the maximum discharge current specified in the Product Specification，
High discharging current may reduce the discharging capacity significantly or cause over-heat.
放电电流不得超过本标准书规定的最大放电电流，大电流放电会导致电池容量剧减并导致过热。
2.2 Discharging temperature 放电温度
The battery discharge temperature is 10-45 ,10~45 environment suggested when discharge with large ℃℃
current,small current discharge suggested under ＜10 or ℃ ＞45 , Discharged under to℃ o low or too high
temperature could lead to battery failure or other conditions.
电池放电环境温度为-20~60℃，大电流放电建议 10~45℃环境下进行，＜10℃或＞45℃建议用小电流进行放电，
过低或过高温度大电流放电将可能导致电池失效或出现其他状况。
2.3 Over-discharging 过放电：
It should be noted that the battery would be at over-discharged state by its self-discharge characteristics in case the
cell is not used for long time. In order to prevent over-discharging, the battery shall be charged periodically to
maintain between 7.4V and 7.7V.Over-discharging may causes loss of cell performance, characteristics, or battery
functions.The charger shall be equipped with a device to prevent further discharging exceeding a cut-off voyage
specified in the Product Specification. Also the charger shall be equipped with a device to control the recharging
procedures as follows:
The battery pack shall start with a low current (0.01C) for 15-30 minutes, i.e.-charging, before rapid charging starts.
The rapid charging shall be started after the (individual) cell voltage has been reached above 3.0V within 15-30
minutes that can be determined with the use of an appropriate timer for pre-charging. In case the (individual) cell
voltage does not rise to 3.0V within the pre-charging time, then the charger shall have functions to stop further
charging and display the cell/pack is at abnormal state.
需要注意的是，在电池长期未使用期间，它可能会用其它自放电特性而处于某种过放电状态。为防止放电的
发生，电池应定期充电，将其电压维持在 7.4V 至 7.7V 之间，过放电会导致电池性能、电池功能的丧失。充
电器应有装置来防止电池放电至低于本标准书规定的截止电压。此外，充电器还应有装置以防止重复充电，
