+ | There are techniques to restore batteries, in particular lead-acid batteries, that are beginning to lose power. The main problem seems to be that they develop a layer of crystals that blocks power. The capacitive chargers that use a capacitor to limit the amps that can flow to a battery seem to pulse the layer off the batteries. | ||
