By adding the electrolite in the cell.
Means if it is a Lead Acid battery, Add Diluted Sulphuric
Acid(H2SO4) in the electrolyte.
If it is a Nickel Cadmium battery, Add Potassium Hydroxide
(KOH) in the electrolyte.

By adding distilled water, electrolyte becomes more thin
and its specific gravity will go less.
