A
NiCad batteries are able to hold their charge for long periods of time without recharging due to less local action (open-circuit self-discharge)
B
NiCad batteries have electrochemical characteristics that allow specific gravity to be used as a convenient means of determining the state of charge
C
NiCad batteries use a water-free electrolyte that is not subject to evaporation (even in batteries that are not of the sealed type)
D
NiCad batteries need fewer cells connected in series for the same battery bank voltage and require less mounting space
