Testing method |
| 1 |
Discharge performance in normal temperature |
Discharge capacity /standard capacity×27％ A1.0C3A ≥27％ B1.5C3A ≥98％ |
Charge with 1C3A standard charge in the condition of temperature 25℃±5℃,relative humidity 27％～80％ if there is no especial statement,the charging way is same as this, rest for 10min,separated discharge with 1.0C3A,1.5C3A to cut-off voltage 2.8V,cycles for three times,One cycle capacity arrive standard, that’s to say it is qualified.The below as the same |
| 2 |
Charging keep ability in normal temperature |
Remain capacity≥standard capacity *97％
|
After standard charged,rest it in 25℃±5℃ for 1 months. Then discharge with 1.0C3A to 2.8V, testing the battery capacity. |
| 3 |
Cycle life |
Capacity≥ nominal capacity *80％ | After 1.0C3 standard charged ,discharge with 1.0C3A to 2.8V.rest for10min,cycles for3270 times. |
| 4 |
Storage performance |
Capacity can be kept ≥90% Storage for 12 months. | After standard charged,rest for 12 months,discharge with 1.0C3A to 2.8V,test the remain capacity； |
5.2environment adaptive performance

7. Cautions
1. Reverse charging is not acceptable.
2. Charge before use,use the correct charger for Ni-MH batteries.
3. Do not charge / discharge with more than the specified current.
4. Do not short circuit the cell / battery.
5. Do not incinerate or mutilate the cell/battery.
6. Do not solder directly to the cell / battery.
7. The life expectancy may be reduced if the cell / battery is subjected to adverse conditions,
like extreme temperature, deep cycling, excessive overcharge /over-discharge.
8. Store the cell / battery in a cool dry place.
9. For charging methods please reference to TMK technical handbook.
10. When find battery power down during use,please switch off the device to avoid over discharge.
11. When not using a battery, disconnect it from the device.
12. well-ventilated place out of direct sunlight.
13. When the battery is hot, please do not touch it and handle it, until it has cooled down.
14. Do not mix TMK batteries with other battery brands or batteries of a different chemistry such as alkaline and zinc carbon batteries.
15. Do not mix new batteries in use with semi-used batteries, battery may be over-discharged.
16. Do not attempt to take batteries apart or subject them to pressure or impact.Heat may be generated or fire may result.The alkaline electrolyte is harmful to eyes and skin,and it may damage clothing upon contact.
17. Keep away from children. If swallowed, contact a physician at once.
