Was a mechanic myself for some years. (Not up to the expertise level as Scotty) He gives simple/sound advise.

Scotty is the best mechanic on Youtube. He uploads lots of videos, do live car talks, answer questions on his website and gives away tools. He's the easiest mechanic on Youtube to get a hold of to ask questions. I look forward to your car talk tomorrw morning. Keep up the good work:)

I stayed away from battery changes but now I can do them myself with this advice. Thank you Scotty.

Thank you Scotty! You are my favorite mechanic, I wish we have more honest people like you. I love all of your informative videos!

[iamteamBB]

that is why i enjoy the older cars. not all that electric crap to deal with. even more fun when u have to replace all that crap too lol

[electronicsNmore]

Yes, newer vehicles do have big problems when you disconnect the battery, which is actually a very poor design, especially for an expensive car like a Benz. There's no reason why the computer shouldn't have a supercapacitor inside them to keep voltage applied in the event a battery goes open circuit or if you need to swap out the battery. I usually use 2 jumper wires connected to the battery clamps, apply 12.5V to 14V, then remove the clamps from the battery.

I always learn something new from Scotty. I've never even heard of this before. I though i just had to reset my radio stations and the clock.

[straitpepperdiet]

I work at an auto parts store and we never use that device. My manager is too cheap to take one off the sales floor for store use. Many times I've changed a battery just to have poor idle. Sometimes the car will have NO idle. It just shuts off if you take your foot off the peddle. So if you take your car to a store that offers free replacement, ask them to use the memory keeper.

I learned something new Scotty, thank you, I never new modern cars can’t keep it’s memory on the ECU, my car’s battery is disconnected right now to prevent theft, but it’s from the 90’s, the ECU doesn’t lose it’s memory. Thanks for the useful upload!

THANKS FOR 3 MIN OF NOT SHOWING HOW TO REPLACE THE CAR YOURE THE BEST SCOTTY BOY!!!!

[jesussalinasr]

Lol iv learned more from Scotty in one week then from my father ever

[zuilok]

You can also save the 15 dollars by just connecting the battery leads to any 11-14V power supply (like a series of small batteries or any charger with the right voltage) while changing the battery. I am sure DIY car guys all have a 12V power supply laying around somewhere.

[davidhester]

Very informative video Scotty. I checked my owner manual and got zero information on battery change. Many other people have posted information on battery changes, but the ones I looked at never mentioned keeping the computer supplied when changing the battery. Thanks again!

[RandyDarkshade]

So why, with all this "great" technology we have in cars these days, the system does NOT have a back up battery installed so the computer does not loose memory? Even home PC's have a battery on the main board so memory is kept when it is turned off.
