Ducati Scrambler 800 - Service manual > Topping up the electrolyte

Remove the battery (Battery).

Warning Before carrying out any operations on the battery, keep in mind the safety standards (General safety rules).

The electrolyte in the battery is toxic and can cause burns if it comes into contact with the skin because it contains sulphuric acid. Wear protective clothing, a face-mask and goggles when adding electrolyte. If the fluid comes into contact with the skin, wash thoroughly with fresh water. If it comes into contact with the eyes, wash thoroughly with water for 15 minutes and consult an ophthalmologist. In the event of accidental ingestion, drink large quantities of water or milk, and continue with milk of magnesia, a beaten egg or vegetable oil. Do not allow sparks, flames or any other heat source to get near the battery, as it produces explosive gases. When recharging or using the battery indoors, make sure that the room is adequately ventilated. Do not inhale the gases produced during recharging. KEEP OUT OF REACH OF CHILDREN.

Place the battery on a flat surface. Remove the protective film (1).

Warning Make sure that the electrolyte is of the specific type for your battery.

Remove the container with the electrolyte from the plastic bag.

Remove the cap strip (3) from the container (2).

Charge system - Battery

Important Keep the cap strip (3) to hand because it will be used later to plug the battery cells.

Warning Do not peel or perforate the sealed areas.

Place the electrolyte container (2) upside down. Align the six sealed elements with the six filler holes on the battery. Push the container (2) downwards with sufficient force to break the seals and allow the fluid to flow out.

Note Do not tilt the electrolyte container as this could interrupt the flow temporarily or even permanently.

Make sure that air bubbles emerge from all six filler holes. Leave the container in this position for at least twenty minutes.

If no bubbles emerge from one of the holes, tap gently on the bottom of the respective container.
