Memory Keep Alive During Battery Replacement 101 - Auta a dopravní prostředky
Great job. Don’t forget anytime there’s only one cable attached to a battery, you want it to be the positive one. Therefore when you reinstalled the cables after replacing the battery, you wanted the positive battery first, then the negative not vice versa just a extra safety measure.
Did everything correct except replace the battery connectors. Should have reconnected the positive first, just as you removed it after the negative.
Awesome! Thank you for sharing such valuable information! Shout out to all technicians doing the most to stay informed and informing others on service procedures! 👍
So, Just a suggestion. I like to plug the "memory saver" into the vehicle's port before I attach it to the 12v.
source, just so there are no issues wiggling the plug into the vehicle. Probably not a huge deal. Just me.
Why is the negative cable going back on first? Your supposed to put positive on first then the negative on last as its earthed/ground
For people saying positive goes first…
You’re not wrong but the whole point of taking the negative cable off first and putting it on last is so that the body of the car is not grounded while you’re messing with the positive terminal. This is so you don’t short something if your wrench touches a metal part in the engine bay while you’re removing/attaching the positive cable.
Given the fact that he was using a driver, which has a mostly plastic housing, and most of the engine bay is plastic, it really doesn’t matter in this case as there was really no risk. But yes it is good practice to put the positive back on first.
Negative comes off first and on last unless you're a gambling man and going for a 50/50 chance of popping a diode in your alternator.
Excellent video, thanks for taking the time to make a video for folks who might not know any better! If a person does buy the battery jumper from Noco it will also boost batteries if needed and is portable. So a person gets to excellent uses.
That's a nice alternative that I can use with my compact jump pack. I have the attachments, all I need is this connector...sweet!
I’m a 37 year tech And your channel is the only one I seem to watch all the way through!
Peace brother
This looks like a pretty good solution. A couple of hours ago I ordered from Amazon a memory saver that goes from the OBD2 port to either a 9v battery or an electrical wall outlet. I think my choice sounds pretty good too.
Glad to see Mechanics are getting some direct profit from their tools and expertise. Wife just paid $60 labor at the dealers to install a new battery. Video's show about a 10 minute swap time (if that)
What sawed me off was it looked like they stripped all my wax-on off the car when they ran it through their "free wash" - wish they'd of asked or notice it had a deep shine to it or something.
Positive first on install.
Exactly
Yep, this was a botch job.
Great video thanks my friend. I have the type you used and also I have the one with the battery pack. Thanks again for the great video
hi Snap On, thanks for uploading this tutorial. what makes the GB-70 support a memory save function as opposed to the GB-40 version? just trying to understand better.
Thank u very much learned how to avoid loosing my car memory &changing a car battery the safe way good job 100%👏🏾👏🏾👍🏾👍🏾👍🏾
Great video and it's just what I wanted to know!!! Thank you!!!
positive goes back on first brother hyundai tech . and I use the battery handles that are attached to the battery when removing the battery
thanks for the video. can i use this kind of device to keep my baiid device powered on while changing parts such as a starter, alternator or any other electrical device on my truck, or does this send power to all those other things also? rendering my maintenance just as dangerous as having the battery connected?
this procedure is good for any car with OBD port? how to know beyond what year are considered "modern"? isn't there a risk of frying the ECU doing this? thanks
Hey I wanted to ask a quick question. I’m a young guy going through trade school to be a mechanic. However I wanted to ask your opinion on torquing everything down. I’ve been told that I need to torque absolutely everything but for years all the techs I know don’t torque anything. Just wanted to know your opinion on whether tech’s have to/should torque everything.
Excellent explanation, thanks .
Hi! Can I use one of these when connecting my multimeter in series with the battery terminal to test for parasitic drain / current or would it mess up the readings?
Yes. Now im a master mechanic. Could never figure out how to change a battery.
Jp love the vids
hope you and the family have a rocking kick ass thanksgiving. also do you have a store to buy shirts or stickers that i can put on tool box so i can represent lol
I have the gb70 boost not the genius I'm wondering if I can do the same thing swapping a battery the light didn't go on the memory saver when I plugged it to the 12v out
I need that. Year's ago ( like 1987) I bought a Blue Point battery saver that was just a 9 volt battery plugged in to the cigarette lighter, never worked on any vehicle. I still have it around somewhere. Thanks for the update on how not to piss off your wife when you change her car battery 😎.
I used this one and it worked. www.amazon.com/dp/B07KCN69LJ?ref=myi_title_dp
Ok i have a jumpack that’s portable like this but it doesnt have a cig port only usb. What if i get a adapter that is usb to cigarette port from amazon for 5$ will that work. Then use the memory saver cable
Useful video, thanks.
How come you put the negative back in first?. Always heard its positive first when you put them back on.
Hope you are joking 😂😂😂😂..........right
It is the positive first when putting back on. He made a mistake.
@@micahhill4786 you are an idiot. When putting back on the positive goes on first. I will not tell you why because I'd rather you go through life being an idiot. Enjoy your stupid life. Fool.
My name is not important u prolly don't have a clue why.🍻
My name is not important Why can’t answer the man’s question without being a pompous ass? You probably don’ even know the answer.
Do you HAVE to use the memory tool? What if you use a different battery than the maker of your car hut a compatable one?
Do I need a spare battery to hook it up or I can just use another car which is running or it's lighter socket?
Would oem remote starter be affected after changing battery on 2010 sierra?
Can I just plug my jump starter on and keep it on while I disconnect the battery? Or will that mess something up?
At 2:42, What is the name of the red cable that you hooked up to the Noco Genius GB70?
Where can i buy that cable? Does it come with the device?
My Audi Q7 requires us to reprogram the car after changing the battery. Would this save me from programming the car when I change the battery? I just wanna make sure.
My jump pack has a 15v aux output. I Fluked it at 16v. Will this damage the electrical system if attached to a Memory Keepalive? Thanks!
I have the GB 70 boost HD will it still do the same thing if I have the adapter?
What years of vehicle is this most important? 2015 and up?
Cool Tool Bro. Great video.
Whats the part number on that impact boot?
The battery booster cannot do this at the terminals with out using the cable in the cabin?
Can I use a solar gen to plug the memory saver into?
Why did you put 124R instead of the AGM battery is had? Correct me if I'm wrong or did you put in the wrong battery. Looks like you needed to put in an H7AGM
Sr I was used the same equipment and don’t work in a corolla 2000.... with the switch in off... I need to put the switch in on for work!?
Could you give more details when you turned switch on and when you turned it off
Did it also keep your fuel consumption read out?
Does the amperage mater? I have the 1000 amp noco.
Pos goes first...………………………………..
Thanks a lot.
Good tip!
I connected my OBD2 saver plug into the OBD2 port of my car, and then connected to cable to the booster box. It did not save the codes. I noticed you connected the booster to the OBD2 plug first and then plugged it into the OBD2 port. I wonder if that's what I should have done.
What iF....You have RemoveD your battery + you have set up your powered memory saving device..you need to halt your battery change..for what ever reason..would this device be able to close car windows..and does it power interior light..and so is it inportant to make sure doors are shut properly to stop power drainage,,and if you locked your doors would this device be able to unlock them..QuestionS..QuestionS!!
how come you dont have the snap on 18 volt battery saver
The battery you took out had a handle on it but you used that clamp?
Does this adaptor work with a 9v battery?
No wonder my car kept on stalling after I change the battery it need it to relearned throttle body and air/fuel mixture I guess 🤷🏻♂️
Just put a 12 Volts Batt connect to the terminal and just need less than a half amp to do the job. Have to be more carefull not disconect wire...
any alternative to gb70? pretty pricey for me
The old battery already had handles on it 😂
he don't play cracked plastic games
I got a question???
If the battery is dead all the way where the clock resets to 12:00 will that screw up everything when you jump start it and shut down all of those extra gadgets?
I WAS a tow jockey for 20 years and came off the road and going to school to become a tech. I'm sorry I haven't towed in the last 4 years.
Is this an issue with all push button starts?
OR?
A common courtesy for your customer?
But you claim that it could keep the windows from rolling down?
So what's the deal?
Great video 👍
I have a question. As you first started to work on cars what brand of tools did you use the most?
As a Canadian I used Mastercraft but my Dad also was a Mechanic and passed down a lot of Snap-on and Mac to me.
@@TheSnapOnToolReview I recently tried to use a memory saver on a 2022 car. It was a cigarette lighter male plug to obd2 port. I used a 12v 10 amp source and I blew a fuse that was stating itself to be 7.5 amps.
Now I am seeing this video use a battery source that I believe produces way more amps at 12 volts. I checked on amazon and your jumpstarter provides 15amp at 12 volts. How the heck did you not blow a fuse? Perhaps that car has a higher fuse in the obd2 port circuit? Im trying to make sure because i cant find any good answers anywherw
Cool. I wonder if I could use an m12 battery.
Cool video I wanted to ask can you change the battery and not lose the memory or settings while the car is running and disconnect the battery and change it out will that affect anything on the car 👍🏼👍🏼👍🏼✌️
Frankie M. I work at Honda and change them with the car running when someone has the memory saver from the tool room. Pretty much the same effect.
@@travisgustin4677 are you saying you don't use the memory saver?
If I put not noco put new battery can I still save my memory
so it just keeps the pcm and modules alive ?
I wonder if I should use this memory saver when I change my spark plugs and clean my throttle bodies.
No need to.
It's only for disconnecting the battery
You dont need to disconnect the bsttery to do the jobs your planning to do
How come you are negative on first?
Others are negative first off and positive on first
Okay so if have to do a repair that requires disconnecting the battery won't this memory saver interfere just as much as having the battery connected even with the battery disconnected since this memory saver is practically doing the same job as the battery ?
You put the words I wanted to say!
I think the memory is in the memory saver, not the onboard computer. After the new battery is connected, the memory downloads and, thus, the settings are retained. If you need to disconnect the battery for repairs on the car, the memory is retained in the saver.
You took - than + than you put - than +. Very logical !
And you don't need that expensive NOCO or any other 200 dollars jumo starter. All you need is that OBD cable, of course, plus a little 12 V - 5 Amps AGM battery that costs about the same as the OBD cable. You than cut the lighter connection and hook up the two wires on + and - of the little AGM battery. That 5 Amps can keep the ECM running for days, if needed. If you want it to keep the ECM alive just as long as you change the main battery, like an hour or so, you can go even cheaper by buying a 2 Amps or 3 Amps battery. I have the little battery glued in a box, for practicality, along with the OBD cable and I used it 4 times in the last 8 month without the need to recharge it. One of those 4 times, I kept the ECM alive for more than 24 hours, I wanted to properly recharge my main battery.
So, you just open the box and take out the OBD connector and you connect it to the car and all is done, the ECM will have power.
It's a very practical and very cheap project.
Do you need to turn key to ACC or ignition at all? Do I even need to insert the key?
@@bmw12347 Nothing at all ! Just don't touch the + and - car's terminals OR the + terminal to any part of the car. There is still current flowing from the little battery all the way to the battery terminals. It will keep all the electronics alive while you finish changing the battery or even while you charge it for a day or two away from the car, if that's the case. You can pick any amperage-hour from 2 to 10 and it will do the job well !
Do you HAVE to use the memory tools or does it permanently mess things up to point you can't reset things without paying a mechanic? Or is it a matter of just resetting clock and radio station preferences? Asking for my daughter who's dumb about cars.😅 I want her to see the answers. 😂
i went to a class they said to use the 3 pin adaptor and not too use the one with all the pins. have you heard of this too curious on your opinion ??
My battery saver data port connector has just 3 pins in it although it is shaped to fit in the ODP slot.
Are you sure you are on the 12 volt out? The jacks are different the cigarette lighter cable fir my NOCO will only connect to my input
I am a dumb ass! I figured it out. Thanks for the video
The safest way to disconnect and reconnect the battery is to take off the negative first then the positive. /Reconnect in the reverse order.
Aside from the fact that your old battery already had carrying handles, you attached the negative terminal first when installing the battery. Crazy!!!!
I agree always positive first... Smh
You made two mistakes, the first is, you forgot to warn that the positive terminal when disconnected it's still live, so if it touches the body or engine there will sparks - ie a short to earth, easy way to do this is just to roll your rubber glove over it when you disconnect the positive terminal. And when replacing a battery you always disconnect the negative first as you have done. but then you went wrong you always connect the positive first and the negative terminal last.
Speed should never be the apparent focus of any operation. It leads to critical mistakes. Ditch the screw gun. Use hand tools and impress your viewers with the planned sequenced execution of your tasks.
Do the ignition has to be on as there's no power supply to the obd2 slot until key is ine the 2nd position?
Did you find out?
@@bmw12347 No, it didn't have to be on position two. Worked a treat.
Thanks
Can you use a battery charger hooked to the terminals before you remove battery?
NO...
3 years on a battery. What piece of crap. Plus I love that plastic piece on top of it.
My Santa Fe is 6 yrs old and battery is still showing on scangauge 14.1 V when driving and 12.8 before starting
WHAT'S WITH ALL THE LIGHTS ON THE DASH?
VW/Audi including BMW,the computer gets wiped out completely when the Battery is changed and has to be reprogramed again.Luckily at my dad's shop,have the GM Tech 2 to unlock the radios.Lot of the radios are programed to the vehicle now
Atypical dealer LOF upsell. Show me the printout from the battery analyzer that my battery tests bad. Most OE batteries should easily give you 5 to 6 years of service, so unless the tech walks me to the car and either shows me my 3 year old 650 CCA OE battery is causing considerable acid leak corrosion damage to my cable clamps and Hyundai will prorates the battery for half off cost ,plus only .3 labor I'm not biting. LOL
What if the battery is dead then it's not needed
not worried about radio but other issues are more important.
I had a customer car not wanting to start. Battery terminal corrosion like crazy. Tested the battery and found that was the problem. (Newer gen Ford Focus) I put in a new battery and the car would never start. Found out that during the battery swap the PCM fried. Another guy I work with said focus’s are bad about that, and when terminals corrode they start corroding through the battery cables right to the pcm and when you change a battery it triggers it to fail. Does that sound correct or could a simple thing like in this video prevent that from happening?
Thanks!
I am having the same problem after putting in the new battery. My 2017 Envision will not do anything. Can you expand on what the PCM is?
@@Charles-in3zt a pcm is the Powertrain Control Module. Computer that controls a lot of things. Never jump to conclusions that the pcm Is bad until someone who knows what they are doing can confirm it
Am I wrong for saying I usually leave the car running when I do the battery change?
+MrBoz2004 on newer cars that can be a very bad thing.
The Snap-On Tool Review exactly, hence the usually, some I do not. But still I see and understand your point.
MrBoz2004 this can cause voltage spikes and will ruin modules on newer cars. Never change the battery with the car running. You may get lucky but before you know it that luck runs out.
I hear that Italian tune up ;) 04:37
POSITIVE GOES ON FIRST! NO BIG DAL GREAT VIDEO!
Always do the rule- negative first,negative last
Wrong order, battery removal = negative, positive: battery replacement = positive, negative
I'd like to see the car turn on after replacing the battery.
Me too that tells us if it works🤷♂️🤷♂️🤷♂️
3 year old battery already hneed changing. What the heck.
do you live in a very cold place? I use Yuasa batteries both in my car and my bike and seem to last at least 4-5 years
Don't for get to add some kind of no-corrode solution so that the contacts don't corrode and ruin the battery prematurely.
Noco sells the Obd memory saver so you won't have do all the wiring jumping Noco part # GC012
Terrible job with the insulator. Hate shortcuts.
I just reset everything.
Good info but your camera spinning gave a headache.
dope ending to video (musically)
Not impressed.
nice 300 dollar ticket
He said shit lol
It's snap on fucking Wednesday
