Lead Acid Battery Desulfator and Rejuvenator Circuit
This technical project presents a comprehensive solution for revitalizing lead-acid batteries affected by sulfation, a common failure mechanism affecting 80% of lead-acid accumulators. The device implements pulse-charge technology to break down sulfate crystal deposits on battery plates and restore electrode surface area. The circuit design centers on a 4047 astable oscillator generating 1 kHz square waves that control a power FET switching stage through an inductor. This generates high-voltage discharge pulses ranging from 15V to 50V depending on battery internal resistance. Three operational amplifier comparators monitor pulse amplitude and drive color-coded LEDs indicating battery health status: green for good condition, yellow for moderate sulfation, and red for severe degradation. The circuit can operate in three modes: preventive maintenance on inactive vehicles, active desulfation of degraded batteries, or continuous operation with a trickle charger. Detailed construction guidance includes component selection criteria, PCB layout considerations for EMI suppression, and usage protocols. The device successfully handles both new battery conditioning and restoration of partially or completely sulfated accumulators.
Lead-Acid Battery Desulfation Guide
Comprehensive technical guide for desulfating lead-acid batteries using chemical treatment. This manual provides step-by-step instructions for restoring sulfated batteries that have lost their ability to hold charge due to prolonged storage without maintenance charging.

Detailed safety precautions are included regarding sulfuric acid handling, including requirements for protective gloves and eye protection. The guide covers a 30 AH battery example with specific dosage calculations of approximately 1 gram of magnesium sulfate per amp-hour. Complete charging time ranges from 10 to 15 hours at the recommended current rate of 3 amperes. Ideal for battery restoration, automotive maintenance, and equipment preservation.
