Memory Keep Alive During Battery Replacement 101

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.

[jordansterner]

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.

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.

I’m a 37 year tech And your channel is the only one I seem to watch all the way through!
Peace brother

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

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.

[ianmellor]

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

[emangee]

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! 👍

[mikemccormick]

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.

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.

[robswrenches]

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!

[melvy]

Thank u very much learned how to avoid loosing my car memory &changing a car battery the safe way good job 100%👏🏾👏🏾👍🏾👍🏾👍🏾

[jimzimmerman]

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

[johngilley]

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 😎.

[joehyundaitech]

positive goes back on first brother hyundai tech . and I use the battery handles that are attached to the battery when removing the battery

[momtazjee]

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.

[jonathanriojas]

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

[d]

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?

[samkitty]

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.

[BuscandoSanaDoctrina]

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!?
