Product performance:
1. Long service life (under normal conditions, the battery cycles
more than 500 times.)
2. High rate charging and discharging performance: under the
charging conditions specified by the company, the battery can be
sufficient in one hour and can discharge with more than 10C
current.
3. Wide temperature range: in high and low temperature environment,
the battery performance is stable, and the working temperature
range is - 10-70 ℃.
4. Good storage performance: at room temperature, the capacity of
the battery remains above 70% after one month storage.
5. Improper use of safety devices: add chemical protection to
prevent polarity reversal and over discharge; add safety relief
valve to reduce internal pressure in case of improper use.
6. High stability: the company adopts the best materials, advanced
production technology and technology to make the battery
performance stable and reliable.
Performance Curves for Ni-MH Cell:
1. Ni-MH Cell Charge Curve At 0.1C For 16h At 55 Degree
2. Ni-MH Cell Discharge Curve At 0.25C At 55 Degree
3. Ni-MH Cell Charge Efficiency At Different Temperature
4. Ni-MH Cell Cycle Life Curve
Ni-Mh Battery and Lithium Battery, Which is Better?
Nickel Medal Hydride Battery and China Lithium Battery, which is
better? This is not a conclusion, both have their own advantages.
Mainly to see what is your appliance? Like lithium battery is
suitable for mobile phone, but in digital camera, has high demand
for current amount, and power consumption is much larger than
mobile phone, the output part of Ni-MH battery is slightly better.
1.Single voltage of lithium battery is 3.2V and 3.7V, single cell
Ni-MH battery 1.2V, Lithium Iron Phosphate Battery with a single
voltage of 3.2V.
2.Lithium battery has no memory effect, Ni-MH battery has memory
effect.
3.Lithium battery does not contain heavy metals cadmium.
4.Lithium battery manufacturing and use is environmental
protection, no pollution.
5.The specific capacity of lithium battery is high.
6.The unit price of Li-polymer battery is high.
7.Li-polymer battery has long cycle life.
8.The lithium battery specifications is more specific than Ni-MH
battery, versatility is not strong.
