Brief Introduction:
1, Together with technology’s imporvement and actual demanding of high temperature batteries, there are many field in great demand of low temperature rechargebale ones.
2, Currently, almost all of batteries of China battery line can stand high temperature rate at 75 degrees.
3, While GMB’s low tem battery can stand at most 80 degrees, what’s more, the capacity is different at various tem range, such as:
| Temperature range | Duration | Capacity recovery |
| -20oC - +80℃ | 10 days | 50%(expected) |
| -20oC - +60℃ | 1month | 75%(expected) |
| -20oC - +45℃ | 3months | 70%(expected) |
| -20oC - +25℃ | 1year | 80%(expected) |
Noted: Do not storage at fully charged state (4.20V) for a long period of time
Characteristics:
|
1.Low Temperature Discharge Capacity(-10oC): 70% (minimum) of Rated Capacity
|
The capacity shall be measured at a discharge current of 1140mA (0.2C) in an ambient
temperature of -10oC ±2oC and a cut-off voltage of 2.75V after the standard charge |
| 2, High Temperature Discharge Capacity(60oC): 100% (minimum) of Rated Capacity |
The capacity shall be measured at a discharge current of 1140mA (0.2C) in an ambient
temperature of 60oC ±2oC and a cut-off voltage of 2.75V after the standard charge |
|
3, Storage Characteristics(25oC):
a/Capacity Retention: 85% (minimum) of Rated Capacity
: 85%
b/Capacity Recovery: 90% (minimum) of Rated Capacity
|
The capacity retention shall be measured at a discharge current of 1140mA (0.2C) and a cut-off
voltage of 2.75V after standard charge and being stored for 28 days at 25oC ±5oC .
Then, the capacity recovery shall be measured at a discharge current of 1140mA (0.2C) and a
cut-off voltage of 2.75V after standard charge
|

4, Storage Characteristics(45oC)
a/Capacity Retention : 60% (minimum) of Rated Capacity
b/Capacity Recovery: 70% (minimum) of Rated Capacity
