Question

Which of the following is the advantage of alkaline battery?

(a) High energy density

(b) Good discharge characteristics over a wide range of temperature

(c) The specific gravity of electrolyte remains the same

(d) Cheap raw materials are used

I got this question in quiz.

My question is taken from Storage Batteries in portion Nonconventional Engines, Conventional Energy Sources & Cooling System of Automobile Engineering

Answer 1

Correct answer is (c) The specific gravity of electrolyte remains the same

To elaborate: The advantage of the alkaline battery is that the specific gravity of electrolyte remains the same. The electrolyte does not take part in chemical reactions on charging or discharging.
