Doing This Will Make Your Car Battery Last Twice as Long

rev up your engines, today I’m going to
give you five ways you can make your car battery last as long as it possibly can,
now car batteries get more and more expensive these days, sometimes the
average battery will be 140 dollars, you want to make sure your battery lasts as
long as possible now the first trick to making your
battery lasts as long as possible is, use it all the time, now I know that sounds
counterintuitive but it’s not, but car batteries aren’t like cell phone
batteries, you use your cell phone the battery drains, eventually it runs out of
electricity, but car batteries aren’t that way, they start your car up but once
they start your car, then your alternator kicks in and the alternator recharge the
battery and runs the engine, car batteries are made so that they
discharge a little, start the car then recharge as the alternator recharges them,
if you just let a car battery sit you don’t use it, they actually go bad just
sitting, now if you don’t use your car much it’s a good idea to get one of
these battery tender type things, what it does is, you hook it up to the battery
and it does a little trickle charge and then every once in a while, it takes a
little energy out of the battery so it’s like exercising the battery so it stays
strong, let’s say you’re not using your car much, it’s a good idea to use one of
those or just take the battery out of the car when you’re not using it, if it’s
sitting for weeks or months at a time leave it on one of those machines and
then put it back in the car when you’re gonna use it, I personally use one all
the time because I live in downtown Houston, got three cars, and I don’t drive
any of them all that much, so whenever I check it with my battery checking
machine, it almost always says good battery but needs recharge, I just put them on the
charger for a while, if you don’t use your car much, hey every once in a while it’s
a good idea to put a little charge into
the battery because it will get weak just sitting there, now the next trick to
making your battery lasts as long as possible, is to keep the terminals clean
and remove any corrosion and nice and tight. because corrosion or loose
terminals create more resistance and the more resistance in an electrical circuit
the harder the battery has to work to send electricity to it
it will have a tendency of getting hot spots, that will eventually wear the
battery out faster, all you need is one of these
99-cent cleaners it’s real good for cleaning them off, just scrape all the
corrosion off of them, then get some spray electrical cleaner, I’m using mass
airflow sensor cleaner it’s the same thing it actually costs more, but I’ve
got cases of this stuff so I use that to clean off any electrical problems, and then
get rid of any residue that might be lying around, then once it dries get some
of this battery spray terminal protector and spray it on the terminals, that seals
the battery acid vapor from getting and eating it up spray both of them, that way
the corrosion won’t come back and you won’t have any problems with those areas
getting too hot from a weak connection and then making the battery work too
hard and burn itself out early, now the next thing to ensure that your battery
lasts as long as it can, is make sure you have the correct battery in your car in
the first place now batteries have ratings on them, I’ll
show you this one, as you can see right here,
this battery has a cold cranking amps rating of 700 cold cranking amps, now
that’s rather large for the Celica and there’s a reason for that, originally it
came with a 500 cold cranking amp battery, but since I don’t put that many
miles on it I kept having to replace the stupid
batteries every couple of years, but when I switched to the 700 cold cranking amp
battery I haven’t had to replace this one for
five years so far, a lot of times you’re actually better putting a better battery
in than the one that it came with, the main purpose of the battery is to start
the car, it needs a lot of power once it’s started, the alternator kicks in and
charges everything up, so the main focus of the battery is to actually start the
car up, and I know a lot of guys say, hey Scotty well when they make the cars they
put a small battery and isn’t it the way it’s supposed to be, no that’s just
because it’s cheaper to make a car that way, and of course they weigh a little
bit less the cheaper batteries and you got like 1/1000 of better
gas mileage for the few pounds you save but it’s mainly because it’s cheaper to make
them that way, now the next way to make your battery last
as long as possible, is every once in a while have your alternator checked, because
the alternator works in tandem with the battery, if one of the other is weak it
can harm the other one, if you have a weak alternator it’s going to make the
battery work harder and wear it out faster and especially if you have an alternator
let’s say the diodes are going bad in it and it
overcharges, it will actually burn out your battery by giving it too much
electricity and destroying it, an alternator is called an alternator
because it actually creates alternating electricity, then the diodes and the
internals of the alternator transform that into direct electricity, and when
things break sometimes the alternator will actually put out alternating
electricity of way too high voltage and that will destroy the battery, it doesn’t
take a mechanic three minutes to check your alternator, you can even buy one of
these Topdon checkers yourselves, their like 50 bucks or so and they do a pretty
good job of checking your battery and your alternator, you want to have them
tested every once in a while, because when they are going out it’s better to
change them sooner than later, because on modern a cars and my own customers
cars, I have had more cars come over here with weird problems, check engine lights
on, they’re running bad, they start up but they don’t run right and the root
problem is either a weak battery, or a weak alternator, so that’s something to
always check when you have a problem in a car right off the bat these days
because everything’s computer run and computers are very sensitive about their
voltage that’s being supplied to them, and if it’s incorrect all kinds of wacky
things can happen to your car that you don’t want, now the last trick to making
your battery last as long as possible is to check the battery acid level that’s
inside the battery every once in a while, you just pop the top off and look inside
if you can see the water level like in these it’s perfectly fine, plates need to
be covered with the battery acid if you see them that means it’s low, just get
some distilled water and pour it in until they’re covered up again, now years
ago they were pushing sealed batteries, where you couldn’t add water, now it
wasn’t that the battery acid inside some of it didn’t evaporate, it still had vents
but those are made that it would evaporate much slower, still when it
evaporated you couldn’t add anymore and you had to buy a new battery, so the
best batteries for a long life are really the ones where you can take the
top off and check them, unless you’re someone who never checks anything, and if
you or your wife never checks in anything, you’re better off with the
sealed battery, because even though it evaporates some, it evaporates slower and
a sealed battery that you do no maintenance at all will last longer than
a battery that has tops that come off, and as I said if you do have one with
tops and come off use distilled water because local water usually has a lot of
minerals in it, and then the minerals will settle to the bottom of the plates
of the battery and short the thing out, so now you know five ways that you can
let your car battery last as long as possible, so you won’t get stranded somewhere
or even worse, have a car that has damage done to it electronically because of a
problem in the battery or the wiring, so if you never want to miss another one of
