Correct Answer - Option 1 : Intensity
During the charging process, it is very essential that the battery is taken out from the circuit as soon as it is fully charged. Overcharging as well as undercharging are undesirable and should be avoided. The indications of the fully charged cell are
- Voltage
- Specific gravity of the electrolyte
- Gassing
- Colour of plates
∴ Intensity is not an indication of a fully-charged cell.
