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
my new car repair videos, remember to ring that Bell!

  21. Joe August 15, 2019 at 2:08 am

    I recently had my battery replaced on a 2014 Nissan Rogue Select S. I want to protect the terminals with grease or terminal spray. Do I have to remove the terminals to apply for the best protection? Worried about presets, idling, power steering. When the dealer replaced the battery, the clock reset but no problem with idling , etc. Does this mean I can remove the terminals without a memory saver?

  22. Tony W August 17, 2019 at 3:11 pm

    I replaced the cheap stock battery in my Nissan 8 years ago with a good quality aftermarket one that was much more powerful. (800 cranking amps vs 500 IIRC) It still works like new and it doesn't produce any corrosion on the terminals at all.

  23. Pyper70 August 18, 2019 at 11:08 am

    Or just buy a dry cell battery and be done

  34. Joe The Barean August 27, 2019 at 2:43 pm

    Just pour Coca-Cola on the battery terminals you will see the acid disappear before your eyes

  35. Lena C August 27, 2019 at 3:23 pm

    1:20 I wonder if it's a good idea to disengage the negative terminal and use a tester to monitor once the % battery charge is weak then hook up the positive terminal again to drive until the charge is back up to 100%.

  58. Curt Chase September 26, 2019 at 2:25 am

    One GOOD thing most of the automotive industry has done, because of computers, is put timers on everything on the car. No more dead battery due to "leaving the radio on", or dome light, headlights, etc. Running a car battery completely flat just a few times will dramatically shorten it's service life.

  59. randy johnson September 29, 2019 at 2:15 am

    CAR BATTERIES ARE SCAMS.MORE EFFICIENT TO USE LARG CAPACITORS SINCE ITS ONLY TO START THE CAR

  60. kyle hackney September 30, 2019 at 7:45 pm

    What if you have a dead cell and then it gets tapped out after so many jumps, do i need to get a new battery or can I buy battery acid and it will fix it

  61. Robert Rouge October 1, 2019 at 12:25 am

    Here is what I learned as to why Auto Batteries have a short life.
    While in the store, I decided to pop off the caps of the new battery, to inspect the electrolyte levels.
    The first battery was so low that 1 of the cells had no acid above the plates.
    On the second and third batteries, I found them equally deficient.
    Having studying Automotive Technology at a Public Technical School, I knew what the remedy was.
    After Sears installed the new battery, I went to my local NAPA auto store and spent an additional $13.00 for 32 Oz. container of battery acid aka sulfuric acid.
    It took almost 8 Oz. to bring the levels to the bottom of the fill ring.
    That was in August, 2013, and the battery is just showing signs of failure.

    Recently while in Walmart, I inspected several EverStart Maxx fluid levels, and discovered the same thing.

    So, why does the factory not fill them to the lower ring?
    Because, if they did, some of the electrolyte would spill out, especially when moved with a Forklift.

    man…trying to figure out if alternator bad. Battery light on, checked battery then battery when car is running and 12.5 both times. next day…light off and did the same check but battery 14.5 when running.? Has done this 3 times in the last 2 weeks. bad Alternator/alternator going bad. or another electrical issue. checked the connection and electric going to alternator

  69. Kelly Bocock October 10, 2019 at 4:17 pm

    Buy a gel cell battery when you buy a battery… Autozone is a good choice.

  70. Kirk Lazarus October 12, 2019 at 9:29 am

    Scotty is right. Any lead acid battery that is not 100% fully charged suffers from sulfation of the cathode, which reduces the active area of the plates. And then the battery can’t deliver it’s cold crank amps to start the car.
    Use a trickle charger at the weekends. A 16 hour trickle charge would be normal.

  71. Richard B. October 13, 2019 at 5:21 pm

    Also dust off the top of the battery iod to prevent a current between the poles . Germans say "Kriechstrom", (kriechen = creeping)

    Use WD-40 is also an alternate choice !

  87. George Rampton October 25, 2019 at 5:01 pm

    I have an older truck that I don't drive very much, and occasionally the battery runs down enough that i have to hook up a charger overnight to bring it up to full strength to start the truck. Rather than having to keep running a 120 volt extension cord out to the vehicle to operate a battery minder, I decided on another alternative. I purchased a small 12 volt solar charger that plugs directly into the cigarette lighter outlet (or clips directly on to the battery terminals). I just keep the solar panel on the dash, facing the sun, or attached to a sun visor that can be positioned forward or to the side, depending on which direction the sun is coming from. Either way, the small solar panel is positioned in a place that will absorb sunshine energy for at least several hours a day. With this easy solar charger installation, I now never have to worry about whether my battery will be fully charged —whenever I need it. A solar charger (with a 4' X 16" solar panel) keeps my battery topped off with a solar trickle charge, and it keeps my battery fully charged. Best of all, I don't have to worry about someone tripping over an extension cord, or having a neighbor's inquisitive children messing a curious cord that conducts 120 volts. This solar solution has worked surprisingly well for over ten years. I have appreciated your informative videos, so this is my way of giving back a tip for your listeners!

    Hi Scotty, My front started battery has finally started to fail after 13 years which is original to the car from the factory. The rear AGM battery still seems to be fine even if I use the TV or stereo for an hour or more. I've had the car for 5 years now but have always put the batteries on charge after doing short trips or heavy accessory use. I'm happy to extend their life as a new set cost over 500 euros, Cheers.

    #1 thing to do is keep top of battery CLEAN or current will travel from positive post to negative post. Drains battery. Just poor Diet Coke over it regularly.
