Data Of Battery Pack:
The data of battery pack, including voltage and weight, is almost equivalent to the multiple
numbers of the relevant single cells.
Example: Battery pack consisting three single cells
Nominal voltage of single cell = 1.2V
Nominal voltage of battery pack = 1.2V×3 = 3.6V
NIMH Application:
MP3, Walkman, E-toys, E-tooth brusher, Brushes shaver, LED torch, Alarm system, Fire
alarm, Mining light, Sex toys, Adult toys.
NIMH Features:
1) High energy density
2) Low self-discharge
3) Long service life
4) Chargeable up to 500 or 1000 times
5) Excellent performance of high rate charge and discharge
6) Low internal resistance
Quality guarantee period:
Guarantee time for one year due to the processing and raw material defectiveness.
Suggestion: The products before delivery would be charged 20-80% capacity according to the
transportation distance and packing condition. While checking the capacity, please discharge
the battery at 0.2C to 1.0V/cell; then charge and discharge the battery at by standard current.
If the storage time over 3 months or above, please discharge the battery at the current 0.2C to
1.0V/cell, then charge the battery at 0.1C for 15 hours, after that place for 20mins, discharge
the battery at 0.2C to 1.0V/cell. After this activation, check the capacity by the standard
current charge and discharge the battery. The first time use suggested to take standard
charge method to charge the battery to prevent from damage to battery.
Notes:
1: Ta: Ambient Temperature
2: Approximate charge time from discharged state, for reference only.
3: IEC 61951:2003 Cycle Life Test:
| Cycle number | Charge | Rest | Discharge |
| 1 | 0.1C×16hrs | None | 0.25C× 2hrs20mins |
