Battery: Precautions for the repair
80A
I - SAFETY
1 - DANGER: RISK FROM ACID LINKED TO
HANDLING
Sulphuric acid is a highly aggressive and toxic sub-
stance 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.
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 at-
mosphere.
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.
II - GENERAL RECOMMENDATIONS
IMPORTANT
A battery contains sulphuric acid, a dangerous sub-
stance.
If acid splashes on to your clothing, rinse all con-
taminated areas thoroughly in water.
If it comes into contact with the skin or eyes, seek
medical attention.
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 con-
tacts, starting or charging faults, sparking, or could
cause the battery to explode.
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 discon-
necting 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.
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.
