Cell Specification
NO | Items | Specifications | Remark | |
1 | Nominal Capacity | 1000mAh | 0.2C Standard discharge | |
2 | Minimum Capacity | 950mAh | ||
3 | Nominal Voltage | 3.7V | Mean Operation Voltage | |
4 | Delivery voltage | Sea&Land | 3.8~4.0V | Within 10 days from Factory |

14 | Operation Temperature and
relative humidity Range |
Charge | 10~15℃ | 0.1C | High/low temperature environment reduce
battery charge efficiency and influence battery life. Long time working under 60 ℃ environment will lead to battery abnormal. |
16~25℃ | 0.2C | ||||
26~45℃ | 0.5C | ||||
Discharge | -10~60℃
60±25%R.H. |
||||
15 | Storage temperature for a long time | -20~25℃≤Six months
-20~45℃≤one months |
Do not storage exceed half year. Must
charge once when storage for half year. Must charge the battery which with protect circuit when storage for three mouthed. (under normal storage conditions for long periods required storage capacity can lead to decay and fall of the life cycle, such as environmental requirements exceeded the storage capacity will be further exacerbated decline and decay cycle life) |
