Keep batteries clean and dry
Dirt on a battery's surface leads to discharge and corrosion. Avoid spilling oil or grease onto the top of the battery. To remove dirt or moisture, wash with a solution of bicarbonate of soda and water. Rinse afterwards with clear water. Ensure vent plugs are in place at all times.
Precautions
To avoid shorting, metallic objects should not be placed on top of the battery.
Batteries contain hydrogen gas and air in a volatile mixture which is easily ignited. Keep flames or sparks away from the battery at all times.
Batteries contain sulphuric acid. Never add acid to cells and keep acid away from eyes, skin, clothing or any other material which may become damaged. If contamination occurs, use large amounts of water to neutralise and flush acid away.
Batteries are also heavy - ensure correct lifting procedures are used when moving batteries.
