1. High power density
The Ni-MH battery is of high power density and good recovery. The Ni-MH battery is 50% smaller than a traditional Sealed Lead Acid battery
2. Excellent high rate discharge performance
The Ni-MH battery allows for extraction of >80-90% of the rated capacity, whereas an Sealed Lead Acid battery only allows for 50% of the rated capacity
3. Long cycle-life
The Ni-MH battery has a service life of 3000+ charge cycles at 8-10+ years with a shelf life that far exceeds the service life of many other batteries .
