Recover Dead Battery using 555 Timer IC

Can recover dead sulfated batteries back to its full capaticy as you may know the lead acid battery actually consists of lead plates that is immersed in the electrolyte of diluted sulfuric acid so the charging and discharging of lead acid battery is actually oxidation and reduction process in thi chemical reaction the lead sulfate has driven and back in the electrolyte and over time with many cycles of charging and discharging the sulfates get permanently attached to the leaf plates reduces attached to the leaf plates that reduces its ability to hold to enough current and that’s when you see your battery with decreased performance or eventually stopped working to protect or recover the battery from this situation a battery needs to be connected or charged with high amplitude pulses generator which will disulfate the Reed plates and dissolves sulfates back into electrolyte I designed the simple circuit diagram and used triple 5 lifetime icy with some other components to generate the high amplitude pulses and with p-channel mosfet to send these pulses to same power source of the circuit then then I converted the circuit diagram to PCB.
