Our Advantages
1. Standard Industrial Ni-MH Battery: long life up to 1000 cycles under IEC61951-2; excellent stability and consistency in OEM/ODM battery pack building.
2. Low Self-discharge Ni-MH Battery: the power remaining is higher than 85% and capacity recover rate is higher than 90% after one year storage.
3. High Temperature Ni-MH Battery: the charge and discharge efficiency under 70℃ is higher than 85%, as for emergency lighting, etc.
4. Low Temperature Ni-MH Battery: charge and discharge efficiency is higher than 70% under -40℃, as for miner’s lamp, etc.; it can be used for more than 5 years under the low temperature.
5. High Rate Discharge Ni-MH Battery: up to 10-20C continuously discharge rate, as for power tools, vacuum cleaners, R/C models, air pump, etc.
6. High capacity Ni-MH battery: High energy density, Rapid charging capability, broad application domain, as for Audio equipment, 2-way radios, other communication devices.
Characteristics
1. High energy density (W/kg), about 50% better than NiCad’s.
2. Typical cycle life is 3000 cycles; can be deep cycled (80% to 100% DOD).
3. Ni-MH batteries also tolerate over charge and over discharge conditions and this simplifies the battery management
requirements.
4. Wide operating temperature range (-40℃~+85℃).
5. Environmentally friendly (No Cadmium, Mercury or Lead).
6. Much safer than Lithium based cells in case of an accident or abuse due to the use of more benign active chemicals, a
particularly important property in high power and automotive applications.
