The line on Pulsetech’s new QuadLink Battery Charger Multiplier is that it can “turn any 6V or 12V battery charger into a 4-station maintenance charger.” I’m sure that’s true but the most obvious charger to use it with is also from Pulsetech, like that Xtreme Marine I first tested in 2007. That unit has been through wringer without a wimper and I’m even more convinced today that it has certain battery healing abilities…
