Reconditioning your car battery (desulfator) Part 2 - The circuit design

This is part 2 of my series of videos pertaining to reviving old car batteries. In this video I will show you where I got the schematic for building the desulfator and once again show you my finished desulfator circuit up close. Here is the part list for newark.com : IRF9Z34NLPBF - P channel mosfet - 1 MR856RLG - Fast recovery diode - 1 1N4148 - switching diode - 1 MCMF0W4FF3301A50 - 3.3kohm resistor - 1 CMF1/41101FLFTR - 1,1kohm resistor - 1 MCMF0W4FF6802A50 - 68kohm resistor - 1 MCMF0W4FF1004A50 - 1mohm resistor - 1 ELXZ350ELL101MF15D - electrolytic capacitor 100uf - 2 MC0805N102J500A2.54MM - ceramic capacitor 1000pf - 1 MCMLR100V103KX7R - ceramic capacitor 0.01uf - 2 MC0805B473K500A2.54MM - ceramic capacitor 0.047uf - 1 2100HT-102H-RC - inductor 1000uh - 1 PM2120-221K-RC - inductor 220uh - 1 MF-RX110 - ptc reset fuse - 1 DILB8P-223TLF - 8 pin dip socket - 1 SA555PG4 - 555 timer chip - 1 Here is the link to part 1 which is the main overview of the desulfator:    • Reconditioning your car battery (desulfato...   Here is the link to part 3 which shows how to connect the led to the circuit to show you that it is working:    • Reconditioning your car battery (desulfato...   Here is the link to part 4 which shows some basic troubleshooting points on the circuit:    • Reconditioning your car battery (desulfato...
