Which of the following types of batteries has shortest life?
A.
NiMH
B.
Lead-acid
C.
Silver-zinc
D.
NiCd
Explanation:
The Nickel-cadmium (NiCd) battery has shortest life that of those Lead-acid and Silver-zinc batteries.
This battery has a nominal voltage of 1.2 volts.
Answer options B, A, and C are incorrect. Lead-acid, Nickel-metal hydride (NiMH), and Silver-zinc
batteries have more life than NiCd batteries. A NiMH battery can have two to three times the
capacity of an equivalent size NiCd.
