Auto battery memory saver

[Irishman]

Need recommendations for an auto battery memory saver.

Don't people just wire alligator clips onto a 9V battery and attach it when they take the service battery out of the vehicle?

i have a memory saver that plugs into the obd plug that hooks up to a 9 volt battery.....works great...got it on amazon...

Sounds good. Plugging into the OBD port is slick and out of the way.

BTW: Do cars with OBDIII (the new one with telemetry) even have a J1961 plug?

That's asking a lot of a 9v battery with today's computers but if it works, it works!

I had one with a cig lighter on one end and the obd on the other. Rigged it to a little motorcycle battery that didn't have the oomph to start anymore.

I got a Weego and it has a barrel connector with which I used my M12 heated gear holsters. But, it seemingly stopped working after virtually no use

What? Obd3 is hypothetical, not a standard, and not on any modern vehicle. Although I’d say Tesla is pretty much doing what people think of when they think of “obd3”

I've used a jump box, negative to frame, positive to the jump stud in the engine compartment or the positive terminal stud on the engine compartment fuse box.

I have a bunch of Bosch Max 12v tools (10.8v nominal). I removed the AC cord and circuit board from a spare Bosch charger and connected two wires from a female cigarette lighter adapter to the positive and negative connectors that are used to charge the tool battery. This is my 12v power source. I use this along with a ODB memory saver with an inline fuse and LED. So, I open the hood, turn off the ignition, remove the key, plug the ODB memory saver into the ODB port, confirm the LED comes on showing power, connect the the male and female cigarette lighter connectors, insert a fully charged tool battery into my power source, then close and lock the doors. When I disconnect the car battery, I place the end of the positive cable in an insulated electrician's glove, then swap out the batteries. Works like a charm.

Instead of reinventing the wheel , you can buy one on Amazon that plugs into your power port ( Cigarette lighter ) .About 10 bucks .
