Bumping the voltage up can potentially get some charge in an iffy battery, but it’s by no means something that should really be done. There’s more to the intelligent charging system than that though

How does this intelligent charging system differ from a standard system Jamie?

I always thought that overcharging a battery was not good for it's health, of course things have come along in leaps and bounds since the Lucas 15 ACR, but I'm confused as to how increasing the voltage can help????


Surely if you increase the voltage, the current flow also increases, which could potentially boil the electrolyte and overheat the plates in the battery?? or is this too simplistic a view.
