One thing to note. Technically, what's done here is OK, but it's seen as good practice to connect the black wire second, and to connect it to some bare metal part in the engine. When disconnecting, you disconnect that black wire first. The reason for this is that, while charging, lead acid batteries can produce hydrogen gas. When connecting/disconnecting the first of the two charger wires there's always a chance of creating a small spark, and it's best to not have that spark right next to the top of the battery where the hydrogen may be venting.
Thanks for your advice. You are correct. I chose to explain it this way because I wanted the video to be simple, and didn't want people to connect to the wrong part of the engine and damage something.
@@psychedeliceuphoria Yeah. Pretty much all cars these days use the entire cars bodywork as the negative (Black wire) in their 12 volt circuits. It saves the weight and cost of having negative wires running back to the battery from everything. Because of this you can use any bare nut, bolt, or bracket that's screwed into the bodywork in the same way as you would use the negative terminal of the battery.
Thanks for watching and commenting. I disagree with this. A lot of modern cars have a battery monitoring system and need to see battery voltage, so that the adaptive charging system and stop start work correctly. The safest way is to refer to an owner's manual.
For a standard 12 v auto battery= 2 amp will take 1-2 days......10amp will take 1 hour......50 amp is for engine start so 5-10 minutes....but that is generally not recomended.
