Dual 12V lead-acid battery repair instrument pulse 

 Specific integrated circuits produced by the duty cycle of pulse current (20% duty cycle, 8330Hz frequency of 30-150ma current) effective removal of sulfur compounds produced by the battery plates of lead-acid battery maintenance, maintenance and repair, greatly extended battery life and reduce the number of battery scrap. The repair device using a pulse wave, while the aging batteries scrapped or two to fix, just one day to a week (depending on battery capacity and the curing degree) can remove the battery plate sulfide, repair rate 80%. 

 The device can simultaneously on two 12V lead-acid battery for repair.
