Memory Keep Alive During Battery Replacement 101

[@condor5635]

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.

[@jordansterner1892]

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.

[@dougpoulton5544]

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.

[@steveburke3923]

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.

[@mtsflorida]

Did everything correct except replace the battery connectors. Should have reconnected the positive first, just as you removed it after the negative.

[@naturestan]

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.

[@ianmellor9122]

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

[@Rectitude4U]

Positive first on install.

[@m5p944]

Exactly

[@Feemy]

Yep, this was a botch job.

[@mikemccormick6128]

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.

[@emangee9268]

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! 👍

[@jimzimmerman5288]

The battery you took out had a handle on it but you used that clamp?

[@robswrenches9501]

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!

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.

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 😎.

How come you put the negative back in first?. Always heard its positive first when you put them back on.

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.

[@ghosttownsentinel5288]

Aside from the fact that your old battery already had carrying handles, you attached the negative terminal first when installing the battery. Crazy!!!!

[@localeboy808]

I agree always positive first... Smh

[@1militarymike]

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.

[@wwaldok]

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.

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 🤷🏻‍♂️

[@eddie4414]

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

[@max41050]

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 ?

[@macmike2]

You put the words I wanted to say!

[@starbasef]

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.

[@michellepernula872]

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. 😂

[@zumik83]

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.

[@bmw12347]

Do you need to turn key to ACC or ignition at all? Do I even need to insert the key?

[@zumik83]

@@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 !

[@samkitty5894]

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.

​@@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?

[@JSTruckRepair]

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!
