Information on Nickel Metal Hydride Battery Technology (NiMH)

Battery Cell Information

Specific Energy (Wh/kg): 100
Typical Cell Voltage: 1.2V
Capacity (mAh): 110-15000
Shelf Life (at 20°C): 3yrs
Operating Temperature: -20°C to +50°C


Charging Information

Cycle Life: 450
Fast Charge Time: 2-4hrs
Overcharge Tolerance: Low
Cost Per Cycle (GBP£): 0.9
Charging Temperature: 0°C to +45°C


Advantages
30-40 percent higher capacity than a standard NiCd
Less prone to memory than NiCd, can be rejuvenated
Simple storage and transportation; not subject to regulatory control
Environmentally friendly; contains only mild toxins
Nickel content makes recycling profitable
Wide temperature range


Disadvantages
Limited service life; deep discharge reduces service life
Requires complex charge algorithm. Sensitive to overcharge
Does not absorb overcharge well; trickle charge must be kept low
Generates heat during fast charge and high-load discharge
High self-discharge
Coulombic efficiency only about 65% (99% with Li-ion)
