How To Charge A Car Battery Without A Charger

How To Charge A Car Battery Without A Charger? You will be surprised how many people have the need to charge their car battery but have no charger to help them do it. There are ways around this conundrum. This is only an improvisation not a recommendation, so avoid it unless you have no other recourse.

  • Do not be misled into thinking you can do without a charger of some kind. You need one with sufficient voltage; obvious and compulsory. The trick is that you can use any charger as long as it has the required voltage potential.
  • If your car battery is 12 volts and you happen to scrounge up a 19-volt charger from, say an electronic device the voltage level of the latter is too high, but it will suffice nonetheless.
  • Since you do not have an actual charger, you will lack positive and negative terminals. Use two new cables, slice off the rubberized material at each end, enough to let you use the metal strips inside to form rudimentary circles or loops that can go around the nodes on your car battery.
  • With the negative cable, make loops at both ends of the wire. With the positive cable, make the loop only at one end; you will learn why soon.
  • Assign one cable wire to be ‘plus’ and the other to be ‘minus’. Any one will do, no need to worry about which as long as you remember their assignations. Color code them or find some distinguishing mark if you need to.
  • Swirl the negative or ‘minus’ loop around the charger’s plug node. If this is, say, a laptop charger the node in question is the plug you use to connect the charger to the laptop. Simply loop the cable around the metal portion; tape it firmly in place.
  • As for the positive or ‘plus’ cable, there is no need to create a metal loop out of the cable strip. Make it bulky – thicken the cable wires at this end – and apply aluminum foil around the stub. This is the part you are going to insert into the charger’s small plughole; the plug that you can insert into a laptop’s socket. The tiny metal tube has the positive wire inside it while the negative loop hugs the outside.
  • Make sure the positive is firmly pressed in or you will see sparks flying when the time comes.
  • Now that one end of the positive is inside the tiny charger tube and one end of the negative is swirled around the same, the other two free and looped ends remain to be attached to the 12-volt car battery.
  • As a crucial rule of thumb, these two wires should never touch or even cross each other. Keep them separate from this step onward. Keep a fire extinguisher spray nearby just in case. Good to be prepared, especially if you are charging indoors.
  • Plug in the charger’s AC, check to see if the wires are not crossed or in contact, see if the appropriate looped ends are around the car battery’s positive and negative terminals, turn the power on, and wait.

Bottom Line

With a full and undamaged charger from an electronic device and two new wires that you altered to suit your needs, you can charge a car battery as long as you stay safe and smart while doing so, not to forget patient.
