Doing This Will Make Your Car Battery Last Twice as Long

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
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
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
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
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
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
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

  2. All the batters these day arnt as good as the old ones you can't get in the them now because they are all sealed think that so u need yo by new one u use to be able to top them up but now u cant.i ask about the lamder bay senser how long would I have to drive in a low gear to clean out my sensor some people say drive in 3 and take it up to 60 can u please let me know

  3. Technically the battery has only two jobs, start the car, and to provide resistance to the alternator charge while the car is running. It's actually the alternator that is powering everything on the car while the engine is running. This is why you never remove the battery while the car is running, doing so removes resistance to the alternator produced current and you'll dry all your electronics.

  4. thanks scotty been having problems nobody could figure it out took it to all these shops paid money got it back it still did the same thing riding sluggish and hesitating i finally figured it out it was the battery cleaned it

    with baking soda and water then coca cola that truck took off like a jet no more studdering sputtering now im gonna go get the stuff you said and im gonna check the water and i forgot the screws were kind of loose they were not tight i tighten them up i am getting good

  5. Back in the 80's I connected an extra tiny piss weak charger to my battery, can't remember how long I took to check it but there was acid dripping all over the concrete and I thought well, that's it, it's finished, however that battery stayed in the Mazda van for 13 years until it developed holes in the top and smelt rather bad.

  6. I hated that white stuff forming on the batteries so I fix it. I stopped buying Japanese junk, Yes that's right I stopped buying that junk. Now I buy German problem solved, Also Japanese cars come with a tiny battery made for motorcycles. Cheap bastards. Germans put a massive battery some times two. Big battery, big strong engine over-engineered car all you need is a bank load of money to keep them running.

  8. Just had an ever start Walmart battery explode inside a back up generator, it was five years old but I’ve never seen a battery explode like that, the top is actually blown off and I’m not talking about the part where you put water in. Is this common? Anyway to prevent it? Thanks

  9. I have a 1990 b2200. I just cleaned the terminals and used grease to coat the terminals. We did this in the army.

  10. I have a lifetime battery warranty. Costco will replace your battery for free within the three years, no questions asked. Before my 36 months are up, I go to Costco and get a new one. 😂

  11. I have to charge my battery about once every 3 months. It’s 1yr old after replacing the old one I had to charge every week. Checked the alternator, took it to autozone and it passed their test machine. 1- what could it be beside a small parasitic draw that’d I’d have to check every fuse and relay and 2- when charging a battery with a wall charger (in my case 4A charger) should I remover the battery from the vehicle terminal lines or just leave it connected?
    Edit: 1999 GMC Sierra c1500 btw

  12. My red top battery lasted 10 years. I open the hood every time I get home after driving as heat is what kills a battery. Just purchased another red top battery and installed it in my 2006 Kia Sportage.

  13. Maybe I'm imagining things but did someone recently give your garage a very professional looking paint job? I was in the business long enough to immediately recognize the top coat as always popular rustic red probably applied with an airless sprayer after plenty of all important prep work. Even the Live Free or Die (my sentiments exactly) sign was removed and painstakingly retouched before being replaced. Since your building is used as a backdrop that has almost become a trademark I can understand why you want it to look cherry. I'm impressed.

  14. Boiled hot water to clean dirty battery contacts, cheaper. Agree installing larger capacity battery will last longer. Installed 560 cold cranking amps battery, up from 400 cold cranking amp. Cranks engine quicker on starting, lights etc…seem brighter.

  15. You have great videos. Thorough & intertaining. When cleanong the battery terminals, take the cable connectors off to clean the entire terminal shafts with the hollow end of that tool..then clean the insides of the connectors with the small end of that $.99 tool. Spray them all with the red protectoant & reassemble & Spray again. Wash the battery with baking soda, rinse, wipe clean & dry the top before opening caps. When filling with Distilled water, a small funnel or turkey baster is less messy. The water level needs to be higher than just covering the fins. That is ok if the battery needs charged since the level will come up some when fully charged. Most betteries have a cylender shaped "neck" with vertical slot in one side. This neck sticks down from the filler hole. The water can be filled to the bottim of the cylender if the battery is fully charged.

  16. The diodes in the alternator rectify or convert the A.C. (Alternating Current) to D.C. (Direct Current). It is the regulator (either internal or external) that controls the output amps for charging. Otherwise very inspiring to us DIYers. Thanks. Keep em coming!

  17. I got a $10 LED battery tester from the supermarket (works a treat) and even when I got nowhere to go I drive the car every three days for 30-40 miles, gives the neighbours a run out following me to see where I go,

  18. I've been using Vaseline as a battery terminal protectant for 50 years. An old mechanic taught me that ages ago. I keep a little dedicated jar in my tool box along with an old toothbrush. Once a year I check my battery terminals and re-apply a little Vaseline on both terminals with the brush. Works great. No getting red spray all over the place — also spraying both battery terminals red could confuse someone was to which terminal is positive. Battery Tenders are a great product. I'v'e more than doubled my battery life on my cars. Eight years instead of four!

  19. So great advice as always. Can you reccomend a battery upgrade for my 2005 Honda CRV? It's fine right now but I am always trying to keep up on my cars needs

  20. I put dielectric grease on the batt terminals. Coats and takes up the micro-gaps in the connections… Good stuff on all your electrical connectors.

  21. Scotty, why wouldnt my radio and clock work after changing my alternator? It isnt a stock radio. Please answer, I trust you! You helped me change my oil!

  22. Small brass brush, a shot of WD40, and some vaseline. Dont let the battery get corroded in the first place. This is not rocket science.

  23. 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?

  24. 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.

  25. At what point does putting all that money into maintaining your battery end up costing more than just getting it replaced when it goes bad?

  26. 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%.

  27. I put tenders on everything that has a lead acid battery (6 of them) that will sit (like over winter). My motorcycles batteries finally died after 14 years! The dealer could not believe it.

  28. You didn't mention anything about battery terminals or did I miss that. Terminals could be good to prevent batteries from draining during extended standing.
