- This video will show you how to change the battery without losing the voltage. For this you will need some gloves, a new battery, a wrench set, and a starter cable.

ta, battery easy changing, changing the battery
This is a dangerous way to replace a battery! Do not use this procedure! It should be retitled “How NOT to change the battery…”
I have a bit simpler way to try, thanks for the video. 😀
Maybe you should provide your "simpler way" that would benefit us to streamline the process.
@@swingbelly Certainly, I might use my jump starter power pack that I purchased from Canadian tire and hook it up to my specialty made jump start points on my Mercedes. No need for two sets of jumper wires or another car battery except the new replacement battery. There is also a devise to connect to the OBD port that provides redundancy or aux power to the car while you are fiddling with the battery connectors so you won't loose your programing. OBD
@@JB73691 Alternatives sound good. Maybe the presenter is on a budget, but it worked apparently!
@@swingbelly His ca did not offer the jump start points . I was a bit nervous when I saw all those jump cables and extra batteries . lol
@@JB73691 Hey. Don't blame you for being nervous, lots of wires to consider and exercising caution when hooking up and disconnecting. Basically though, one is using an auxiliary power source, whether spare battery or a charger to provide electricity to the main computer while swapping out the dead battery. Depends on what equipment is available at the time and the "cost". One could also use an inexpensive and simple OBD2 analyser/memory saver device that plugs into the port and connects to a power source (battery/charger). So much easier and safer without fuss of the wires. Check out the Chris Fix recent UTUBE channel episode on "Complete Battery Maintenance" (all of Chris' stuff is REALLY GOOD) or those of Scotty Kilmer, the "Master". The batteries to both my vehicles died during the recent frigid -31C snap here in Toronto; both were about 5+ years old. I used the OBD2 memory device plus a 12 volt lawn tractor battery when replacing both. It was so easy! They are simple, easy to use and CHEAP, decent ones cost less than $20.00 on Amazon.
Very good, simple conversion. Thanks to your video wife for providing the background verbal support. What a team!
I spotted the deliberate mistake, you disconnected the live connection from the leed that was to keep the memory in the ODB2, so you would have lost that memory.
Also when disconnecting a battery it should be Earth then Positive and when reconnecting it should be Positive first Earth last.
I think that is too risky that the clips might come off. I think the best way is a small 12v battery connected to an OBD-11 plug.
My thought too. Those big alligator clamps seem to pop off of whatever they're connected too. Would totally ruin your day.
Lol this is so fucking dangerous. Dude doesn't even have a socket wrench?
What a pain in the tush. Just get a memory saver and plug it into the obd.
This guy is making it too complicated and too dangerous. Avoid this method at all cost or else one slip and you will fry your car's electronics or fry the battery itself. This video is a danger signal.
Definition of genius is taking the complicated and making it simple… this is not that. Just pay $20 for an OBD-II memory saver without the risk of sparks flying.
