Which of the following battery chemistries is not rechargeable?
B
Answer
Electronic components and circuits
Type
A
Nickel-cadmium
B
Carbon-zinc
C
Lead-acid
D
Lithium-ion
Answer Notes
Carbon-zinc batteries are primary cells, meaning their chemical reaction is not easily reversible and they are designed for single-use only. Once they are depleted, they must be discarded or recycled.
In contrast, Nickel-cadmium (NiCd), Lead-acid, and Lithium-ion are secondary cells designed specifically to be recharged. Attempting to recharge a primary cell like a Carbon-zinc battery can cause it to leak or rupture.
