8. Battery

Fit the battery so that it is properly ventilated.

Maintenance should only be carried out by qualified personnel.

If replacing the batteries, use the same type of batteries. Do not throw the old battery in the fire.

Only use insulated tools (the operator should not be wearing a watch, chain or any metal object).

Never use sulphuric acid or acid water to top up the electrolyte level. Use an approved battery fluid.

Batteries release oxygen and hydrogen gas, which are flammable.

Never bring flames or sparks near the battery (risk of explosion).

Discharge any static electricity before handling the batteries by first touching an earthed metal surface.

Do not use the battery when the fluid level is below the minimum required level Using a battery with a low

electrolyte level could result in an explosion.

Do not short the battery terminals with a tool or other metal object.

When disconnecting battery cables, remove the cable from the negative (-) terminal first. When reconnecting the

battery, connect the positive lead (+) first.

Charge the battery in a well-ventilated place, with all the filler caps opened.

Ensure that the battery terminals are correctly tightened. A loose cable clamp can cause sparks that could result in

an explosion.

Before servicing electrical components or performing electric welding, set the battery switch to the [OFF] position

or disconnect the battery negative cable (-) to cut off the electrical current.

Electrolyte contains dilute sulphuric acid. Careless handling of the battery causing contact with sulphuric acid

could damage your eyesight or cause burns.

Wear safety goggles and rubber gloves when working with the battery (topping-up fluid, charging, etc.)

If electrolyte comes into contact with your skin or clothes, wash it off immediately with plenty of water, then

carefully wash the area with soap.

If electrolyte comes into contact with your eyes, rinse immediately with plenty of water and seek medical attention

as soon as possible.

If electrolyte is accidentally swallowed, gargle with plenty of water and drink large quantities of water. Consult a

doctor immediately.

Large quantities of electrolyte should be rinsed off using a neutralising agent. A common method is to use a

solution of 500g of bicarbonate of soda diluted in 4 litres of water. The bicarbonate of soda solution should

be added until the reaction has finished (lather). The remaining liquid should be rinsed off with water and left

to dry.

Danger

 Dry batteries do not require any servicing

 Batteries ready for use must be recharged at the latest when the acid density drops below 1.20.

8.1. Storage and transport

 Batteries ready for use must be stored in a cool and dry place (frost-free) protected from the sun (self-discharge).

 Batteries must be transported and stored vertically (risk of acid spillage)

 Leave the terminal cover on the positive terminal
