Renault Clio: Battery: Precautions for the repair

Renault Clio III (2005-2013) Service Manual / Electrical Equipment / Battery / Battery: Precautions for the repair

I - SAFETY

1 - DANGER: RISK FROM ACID LINKED TO HANDLING

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.

IMPORTANT

A battery contains sulphuric acid, a dangerous substance.

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

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

Incorrect tightening could cause heating of contacts, starting or charging faults, sparking, or could cause the battery to explode.

When a battery is charging, oxygen and hydrogen are produced. The mixture of these two gases is 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.

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

II - 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.
