Renault Koleos Service Repair Manual / Electrical equipment / Battery / Battery: Precautions for the repair

I - SAFETY

IMPORTANT A battery contains sulphuric acid, a dangerous substance.

If acid splashes on to your clothing, rinse all contaminated areas thoroughly in water.

If it comes into contact with the skin or eyes, seek medical attention.

1 - DANGER: RISK OF ACID WHEN HANDLING AND WHEN MOUNTING IS INCORRECTLY TIGHTENED

Sulphuric acid is a highly aggressive and toxic substance which corrodes most metals.

When handling batteries, it is very IMPORTANT to take the following precautions:

protect your eyes by wearing goggles,
wear acid-proof gloves and clothing.

2 - DANGER: RISK OF EXPLOSION LINKED TO CHARGING AND TO INCORRECT TIGHTENING OF THE TERMINALS

IMPORTANT To prevent damaging the battery or even causing it to explode, do not place any heat sources or create any sparks near a charging battery.

WARNING Poor contact may cause starting or charging faults, create sparks and cause the battery to explode

When a battery is charging, oxygen and hydrogen are produced. Gas formation is at its maximum when the battery is completely charged. The quantity of gas produced is proportional to the intensity of the charging current.

The oxygen and hydrogen mix in the free space on the surface of the plates which forms an explosive mixture.

This mixture is highly explosive.

The smallest of sparks or heat sources can cause an explosion. The explosion is so strong that the battery can shatter and spray the acid into the surrounding atmosphere.

People nearby are at risk (exploded fragments, acid splashes). Acid splashes are dangerous. They also damage clothing.

Safeguarding against the danger of explosion, which can be caused by handling a battery carelessly, must be taken very seriously.

IMPORTANT To avoid all risk of sparks, ensure that all electrical consumers are fully switched off.

When a battery is being charged inside a building, switch off the charger before connecting or disconnecting the battery.

Do not place any metallic items on the battery as this may create a short circuit across the terminals.

Never hold a naked flame, welding gun, blowtorch, cigarette or lighted match near to a battery.

II - CLEANLINESS

Check that there is no salt leakage (sulphation) on the battery terminals.

Clean the battery terminals if salt has accumulated.

III - GENERAL RECOMMENDATIONS

WARNING These vehicles are equipped with a battery with low water consumption. Topping up the electrolyte is therefore prohibited.

WARNING Before disconnecting the battery:

wait for the motor-driven fan assembly to stop,
wait for the computer to finish saving (1 minute).

WARNING Some vehicles are only fitted with " TB " (low height) batteries. To avoid damaging the bonnet, only refit a battery which is identical to the battery originally fitted.

When refitting the battery or every time it has been disconnected, carry out some reprogramming without the diagnostic tool, so that the vehicle operates correctly.
