I recently ordered a $37 battery desulfator kit. It looks like a pretty simple device that sends pulses to lead acid batteries to help clean the battery plates. There are many success stories on the net about resuscitating essentially “dead” lead acid batteries. Since we have two electric vehicles and live off grid we have a lot of motivation to take care of our batteries. I’ve seen kits that sell for hundreds of dollars, but this 555 based kit seems to kick out a lot more juice than the fancy ones with wimpy solar panels.
