Question

The indication of the state of charge of a battery is best given by:

• A. specific gravity of electrolyte
• B. temperature of electrolyte
• C. colour of electrolyte.
• D. level of electrolyte.

Answer 1

The correct option is A specific gravity of electrolyte

During the charging and discharging time, the value of specific gravity of electrolyte varies. For example, during the charging time, the value of specific gravity increases from the electric current level and during the discharging time, the value of specific gravity decreases from the electric current level. But, the rest of all factors which shown in above are not changed. Hence, the state of charge of a battery is given by the specific gravity of electrolytic.
