SAFETY PROCEDURES IN REMOVING/REPLACING BATTERY
Introduction:
No matter how well your vehicle is working, if your battery dies and can’t be
recharged, you’re stranded in a vehicle that you can’t drive in for service.
A battery usually has a sticker on it that shows when you bought it and how
long you can expect it to survive. To prevent being stuck on the road with a
dead battery, enter that information in your owner's manual and have the
battery replaced before it comes to the end of its life expectancy.
Prepare your tools and materials:
CLEAN LINT-FREE RAGS
ADJUSTABLE WRENCH
DISPOSABLE LATEX GLOVES
BATTERY BRUSH
SAFETY GOGGLES
Procedure:
1. Safety Gear:
Put on safety goggles to protect
your eyes from battery acid
splashes.
Wear rubber gloves to shield
your hands and skin from
direct contact with battery
acid.
2. Ventilation:
Ensure you are working in a well-ventilated area to dissipate any
potentially harmful gases released during battery maintenance.
3. Fire Extinguisher:
Have a dry chemical or CO2 fire
extinguisher within reach in
case of a battery-related fire or
electrical fire. Know how to use
it.
4. Battery Disconnect:
If the vehicle has a battery
disconnect switch, use it to cut
off power to the battery.
5. Turn Off Engine:
Ensure the vehicle's engine is turned off.
6. Negative Terminal First:
Always disconnect the
negative (black) battery
terminal first to prevent
accidental short-circuits.
7. Protective Covers
(Optional):
If available, install
battery terminal
protectors on both the
positive and negative
terminals to reduce
the risk of accidental
contact.
8. Tools Ready:
Ensure you have the necessary tools, such as a socket wrench set,
battery terminal cleaner, and brush, within reach.
9. Remove Battery Hold-
Down:
Use the appropriate
tools to remove any
hold-down bolts or
brackets securing the
battery in place. Keep
these fasteners in a
safe location for
reinstallation.
10. Lift Out the Battery:
If necessary, use a
battery carrier strap
to safely lift the
battery out of the compartment. Be cautious, as batteries can be
heavy.
11.Place Battery in Safe
Location:
a. Set the removed
battery on a
stable, non-
conductive
surface away
from the vehicle
and any potential hazards.
12.Inspect Cables and
Terminals:
a. Inspect the
battery cables
for signs of
damage,
corrosion, or
fraying. If
needed, clean
the terminals
and cable ends
with a battery
terminal cleaner
and brush.
13.Replace Battery:
a. If replacing the
battery, ensure the
new battery is of
the correct size and
type for the vehicle.
14.Test and Verify:
a. Turn on the vehicle and check the functionality of electrical
components, such as lights, radio, and air conditioning, to
ensure everything is working correctly.
15.Dispose of Old Battery Properly:
a. Dispose of the old battery responsibly by taking it to a recycling
center or an authorized battery disposal facility.
16.Clean Up:
a. Clean up any spilled battery acid or debris using appropriate
safety measures and materials.
17.Safety Check:
a. Perform a final safety check to ensure all tools are accounted
for, and the work area is clean and safe.
Note:
Batteries are filled with a toxic, corrosive liquid and must be disposed of
properly. What’s more, old batteries are usually rebuilt into new ones, so just
throwing one in the trash is doubly bad for the environment. If you have your
new battery installed when you buy it, the shop will recycle the old one for you.
