If your car's cranking slowly or not at all,
then it's probably time for a new battery.
It's an easy job.
You can do it yourself.
I'll show you how.
The first thing to do is check your car's owner manual
to find out where your battery is.
Some are in the boot, but most are in the front.
And also, just check there's nothing special
you need to do when changing the battery.
If you're in any doubt, just call an auto electrician.
Now, you want to replace your battery approximately
every three to five years.
And always wear safety glasses and gloves when doing the job.
Now, to ensure that you do get the correct battery
for your car, just take a whole lot
of photographs of your existing battery, of all the details--
take that into store and buy yourself a new one.
Now, just before we crack into it,
you want to make sure that your keys are out of the ignition.
And if your car does have a fob, make
sure there's at least 2 meters away from the car.
If you do you have a cowling that goes over your battery,
just release those screws or bolts to reveal the battery.
The first thing we want to do is remove the terminals
off the negative side.
That's the black side.
Now, just make sure that you do have the correct size
socket or spanner when removing the terminal.
Now, the reason why I'm starting on the negative first--
if I was to start on the positive first, that's
the red side, and my spanner was to touch the body of the car,
we could short out the system in the car.
The next thing we do is remove the positive.
That's the red side.
Just take those off and tuck them well away.
The next thing we want to do is take the clamp off
that's holding the battery down.
Now, it's important to take your old battery
to an automotive battery recycler.
It has toxic components and can't be thrown out
with regular waste.
Now it's time to remove our battery.
Now, just before we install our new battery,
there's a couple of things we want to do first.
We want to check that our terminals are nice
and clean-- there's no rust or corrosion on them.
And the second one is to make sure that our tray
that our battery sits on is nice and clean also.
These terminals are looking really good.
But if there was corrosion on them, what I could do
is give them a clean-up with a wire brush.
Or I could make a mixture of water and baking soda,
and then just rinse that off.
If the clamps or cables are corroded,
now is the time to replace them.
And if you see any corrosion or battery acid around the engine
or on your paint work, rinse it with water to dilute it.
Righty-o, time to put in our new battery.
Now, just make sure that you're positive-- your red side--
is on exactly the same side that it was before.
Let's just seat that in our tray,
make sure it's sitting there nice and level.
And we can then put on our clamp,
and we'll just tighten that back up.
Just make sure that you remove your plastic caps that
are sitting on top of your new battery.
Now, just before we've put on our terminals,
we just want to apply some high temperature
grease to each terminal.
This is going to ensure no corrosion,
and also making sure that we get a good connection
with our battery.
Now, when I removed the battery, we
took off our negative terminal first.
When we're installing, we want to do the opposite.
We want to install our positive terminal first.
Just ensure that that terminal is
seated as hard down as we can possibly
get it onto the battery.
I'm just going to tighten that up.
Make sure they are secure but not overtightened.
And then just put on your negative terminal.
OK, now that our battery is in, all I've got to do
is turn the car on and make sure that everything
is working correctly.
