Question

State possible cause of sulphation in battery

Answer 1

Answer:

Causes of battery sulfation:

Batteries sit too long between charges. ...

Battery is stored without some type of energy input.

Undercharging of a battery to only 90% of capacity will allow sulfation of the battery using the 10% of battery chemistry not reactivated by not completing the charging cycle.

Answer 2

Answer:

hey mate here is your answer

Sulfation happens inside Lead–acid batteries when the electrolyte starts to break down. As the sulphuric acid (electrolyte) splits up, sulfur ions become free forming crystals. These sulfur ion crystals then stick to the lead plates of the battery, thus forming lead sulfate crystals
