Box for desulfator

thingiverse

Lead-acid batteries typically experience a decline in capacity over time due to plate sulfation. This degradation can often be reversed by various methods (EDTA, Epsom salt), but using a desulfator is generally the most convenient approach. A desulfator is an electronic device that must be connected to the corresponding battery and generates high-current, short-duration electrical flows at a frequency of approximately 1 to 2 kHz. These currents effectively dislodge sulfites from the plates back into the acidic solution. Numerous products, schematics, or kits are available for desulfation. One common design is used in an assembled and soldered kit (https://www.aliexpress.com/item/Free-Shipping-12-Volts-Lead-Acid-Battery-Desulfator-Assembled-Kit/32274107267.html), which can be purchased at discounted prices online. This kit is designed for 12 V batteries. Since the provided kit does not come with an enclosure, a custom one was created to house it. The custom enclosure consists of three components (box, cover, and a clamp for securing wires). In addition to the printed parts listed below, the following materials are required: 1. A single self-tapping screw measuring 2.9 x 9.5 mm 4. Four self-tapping screws measuring 2.9 x 6.5 mm The assembly process is straightforward: Attach the PCB to the box using the four screws. Pass the wires through the two slits and secure them by fastening the printed clamp to the box. Test the device to ensure it functions correctly. Once verified, apply adhesive to secure the cover to the box. Correct operation can be observed through a hole in the cover. For added protection, a transparent material can be glued onto the inside of the cover before attaching it to the box.
