Compact construction, good sealing, the battery can be installed with other equipment in the same room, can be vertical or horizontal installation, small footprint, good vibration resistance.
Don’t exist the shortcoming of “memory effect”(referring to the cycle of work, the capacity loss) of nickel-cadmium battery.
