Low-voltage batteries have the following characteristics:
(1) The battery voltage is 1.2 ~ 1.3V, which is equivalent to batteries cadmium-nickel.
(2) High energy density, more than 1.5 times that of cadmium-nickel batteries.
3) It can charge and discharge quickly and has good low temperature performance.
(4) It can be sealed and has greater resistance to overcharge and discharge than other batteries.
(5) No dendrites are generated, which can prevent short circuits in the battery (pillar type).
(6) Safe and reliable, no pollution to the environment, no memory effect, etc.
High voltage batteries have the following characteristics: (1) High reliability. It provides good protection against over-discharge and over-charge, can withstand higher charge-discharge rates and has noformation of dendrites. Has good specific characteristics. Its specific mass capacity is 60 Ah/kg, five times that of nickel-cadmium batteries.
(2) Long life, up to more than 500 cycles.
(3) Fully sealed, low maintenance.
(4) Excellent low temperature performance, capacity does not change significantly at -10°C.
