To make this simplest yet effective battery desulfator with charger circuit you would just require a suitably rated transformer, and a bridge rectifier. The design not only desulfates a battery, it keeps the new batteries from developing this issue and simultaneously charges them to the desired levels.

The earlier article comprehensively described the circuit details of an MPPT using PIC16F88 microcontroller, here we get the access to the source code for programming the PIC and the HEX file format for the same.
An MPPT as we all know refers to maximum power point tracking which is typically associated with solar panels for optimizing their outputs with maximum efficiency. In this post we learn how to make a PIC16F88 microcontroller based MPPT circuit with a 3-stage charging.
