pinoyeh: Informative video, but, you forgot to record the saved FM stations from the
car radio. Oh by the way, I still have the original factory battery from
my 2006 Mazda 3, and it is still alive and kicking......
Morahman7vnNo2: But wait, what about checking the amps?
Fake Man: Great video man! Saved my ass!
Yevgen6R: Thank you for the lesson!
sam aarya: ur video saved me well over £500. big thanks
Eric Cable: Thanks for the video. I think I will try replacing myself instead of paying
sam aarya: hi great video a lot of help.thanks
my car reading during crank was 6.5.it would not start and the maintenance
free battery has a small window with a green light inside,so im not sure if
the battery if at fault or the starter!
chapin Burgess: I didn't understand one part. As you took the old battery loose you said
"don't touch any metal" then you grabbed a metal tool and stuck it to the
metal of the battery connector. Also, your title indicates that you will
show how to the the amps. I never saw you do it. I pay for my internet by
data used and I watched this for solely how to test the amps so I wasted my
data. Can you correct your title?
cameron cadogan: it sounds to me like the solenoid for the starting motor ain't moving the
Derek Miller: Yeah that's not showing how to measure amps at all. Just voltage drop when
Joseph K.A: Good simple video.
LiarWithFire: really helpful, thanks for posting!
Asphyx1ation: Why did you put the battery on the floor? You do know that putting any
battery on the floor discharges the cells. I actually went to school for
automotive and they said ABSOLUTELY not to put a car battery on the floor,
your battery will drain faster. usually car battery's last about 3-5 years,
that battery will probably last about a year and a half or maybe two years.
Their was test's done by this at the ASE Academy.
Other than that Very Great Video! Makes me remember high school day's when
I took automotive classes.
KC2DAA: Nicely done video, you make mention of shorting out the battery but then
remove the positive lead first. I would suggest the safest method is to
remove the negative lead first effectively isolating the battery from the
rest of the vehicle..
DizThaWhiz: Articulate, informative and easy to understand. Thank you man
Odysseus Ithaca: Thanks Johnny!
Sacra Mental: So many things in this video that where incorrect...
Major freakup and expensive repairs waiting to happen: Disconnection of
Positive terminal before negative can result in expensive damages that can
also HURT you!
You should always disconnect Negative first, then when reinstalling the
battery NEGATIVE should be the LAST one to connect....
I wonder how many people have shorted directly to the battery post
renoel55: Only one comment ... Jewelry on hands should be removed prior to
performing any sort of electrical work, automotive or otherwise.
Johnnysshop: Just a standard battery.
talkntribe: @Johnnysshop Thank You for replying. I took a multimeter and set it to 10A.
Found out that the meter is reading 0.60-0.65. I definitely have a drain
somewhere.lol. Now, I have to figure where. Thanks helping :)
Johnnysshop: Thanks for watching!
roon demahom: I likes these type of video clips. Excellent presentation. Short & sharp.
Easy to understand & very informative theory & practical. Thru my best of
experience in this field, I'll give to Mr. Johnnysshop rated nine stars
over ten stars. Double thumbs up to Mr. Johnnysshop. You done a good job.
Keep it up your good works & bring out all your best of experience to
everybody. Once again thanks for your very useful info.
freestyletube: Get interstate or die hard best batterys in market
nthankx: as you say show about AMPS but your video describe only Volt so pls change
ofromva: Eric The Car Guy said to use the amp setting. Should i use volts or amps?
Sorry idk much about electrical systems. I dont want to mess up my new
Adrian Wilson: Damn, dude nice vid.
louisfriendhastaste: No. THANK YOU.......that was really useful, now I know what settings and
levels to look for.
fb3333: hi, great video, but you made one important safety mistake. when connecting
the terminals, you should always connect the positive (red) first, so there
is no risk of the arking out as you mentioned, and disconnecting the
battery terminals, negative (black) must be removed first as you rightly
bruno2260: You didn't clean the cable ends or grease the terminal connections! Also if
you didn't install the battery box up-side-down it would accommodate the
battery handle. Put the box in 1st (flange side down). Then drop the
battery in. If you are that concerned about the handle height just zip tie
it to the battery bracket and It wouldn't stick up no higher then the
bracket bolts. Btw where's the cover @ 3:20, forget to put it on last time?
Ha, ha! Anyway you did do good with the meter. Thumbs up.
Johnnysshop: Thanks for watching!
CK: Good vid!
Johnnysshop: Sounds like it is for sure.
Johnnysshop: Thanks. The battery on concrete thing is a myth. Had one stored in my
garage for 2 years.
Veclenit Tavuc: good video thanks :P
Boris theBlade: Yo, i used your video and went and tested mine. When the engine was off i
got 12.67, when cranking it dropped to 10, and running it was at like
13.95. The last reading, is that bad? im sure it should be 14.4?
Johnnysshop: @altpath Hmmm.. I doubt it's either. Now if it wants to die when you turn
the lights on that could be the alternator.
Justaguy913: Ok.... one dumb question XD I know larger trucks and some cars have bigger
batteries. Does your '05 Altima have a larger than normal battery? You read
about 12.3 volts on the meter... and said it was about half charged. Do you
have a 24 volt battery.... or a standard 12.6 volt??
snnnoopy: Okay, I'm a little slow here so bare with me. So, the reading BEFORE the
car starts is the COLD cranking amps and cold cranking amps is for 0
degrees F. Right so far? So, how do I know if my car will crank at -20?
kenny50776: @rpruneau68 That is what I had to say. The way he did that can blow the
battery up in hi face or anything else close by.
Johnnysshop: @digdogitty Thanks, I appreciate the feedback. Yeah, I never trust a
battery no matter what it reads because the load value is what really
counts. Wish you would have seen it first also! Alternators can be a pain.
Johnnysshop: @confederatetexan1 Thanks!
Imre Csoka: Brilliant Video, i have an OPEL CORSA vehicle ( formerly from Delta and now
General Motors ) 1.6 ie and i have also learned about batteries a bit and
wanted to know more about how to measure the amps. I also learned that at
12.3 its not really enough to start the car. 12.6 is very good. As you say
though, its more about the actual amps.
Daniel Alpert: Yes, correct. Always remove negative first and reinstall ground last. That
way if you do short the wrench across a piece of metal under the hood the
battery doesn't cause a spark. I've seen metal melt instantly by
accidentally touching the pos post to a ground source. If the negative
cable is removed first then this won't happen.
Johnnysshop: @ccipherscope Thanks for watching!
DG1entertainment: Thanks for the info
Imre Csoka: but tell me, how do you actually measure the amperage though? is this just
but checking that the battery voltage does not drop as low as nine volts
when u start the car? I guess it is dependent on the car electronics and
what there is to power up ? I have a battery in my car i been driving with
it in the back seat for at least 1-2 years now... i know it was reading at
10 volts the last i checked - is there a use for it, or should i just take
it back to the battery shop and get a few bucks?
1774821: I have a pre battery check question for you. My pathfinder has been turning
over slowly for the past two weeks but always starts. When I turn the
lights on there dim, and then as I start it up they get brighter. Is this a
Battery issue?? Thanks!!
Imre Csoka: I would like to buy a decent multi-meter again but i am not sure which to
buy - the last i had the fuse blew and also the red wire came loose from
the red connecter pin.
