Battery Desulfator Diy Basics: You Can Really Build One

By now, you’ve probably heard plenty of information about battery desulfation and reconditioning, and now you may actually be thinking of giving it a try. And what better way to try reconditioning than by doing it with your very own, self-made desulfator, right? The primary benefit of making your own desulfator is that you can save a significant amount of money than if you bought one from an electronics or automotive shop.

Can I Really Build A Battery Desulfator?

The good thing is that it is easy enough for anyone to undertake a battery desulfator DIY project. Most of the parts and materials you need can be found in the junk box, which you’ve probably stored away somewhere in your basement or garage. An empty, standard-sized can, cardboard, perforated board, pots, resistors, switches, pop-rivets, grommets, output wires, adhesive copper foil, LED, and FET are easy enough to find in your junk box, right? Even if you don’t have these materials on hand, they are readily available at very affordable prices at your local hardware.

Starting The DIY Project

Once you have all the necessary parts and materials prepared, the exciting part of a battery desulfator DIY project can officially begin. The first step is to build the box for your desulfator. This is done by cutting out a piece of the perf-board that will fit snugly into the inner bottom part of the empty can. Arrange the circuit parts on the perf-board according to your desired position. At this point, it would help if you have a schematic diagram to serve as your guide in building the circuit, especially if this is your first time to build a desulfator.

Insulate Properly

Since you are using a metal can as the desulfator’s box, proper insulation is necessary. Cover the lid and sides of the can with thin cardboard. Now, you are ready to start drilling the necessary holes and then solder the wires into place. Drill one hole on the left side of the can for the output wires and then drill three vent holes on the other side. You may also drill a hole on top of the lid so that you can observe the LED while the desulfator is in use. As soon as all the holes have been drilled, you may position the wires and solder them in place as shown in your schematic diagram. Now, decide where exactly on the perf-board you would like to place the FET and then glue it into place.

Voila! Your battery desulfator DIY project is complete. Now you can try your hand at battery reconditioning. If you don’t have an old battery that you can practice on, you may go looking for abandoned “dead” batteries and use them for your purposes. If your reconditioning practice is successful, then you could sell the reconditioned battery to someone at a discounted price. Who knows, you just might end up with your very own battery reconditioning business. You’ll never realize how limitless the possibilities are unless you give it a try.
