Hi Brian, I also have a Schumacher charger, model SC4. It seemed to work well enough for my purposes. A couple years ago a cycling bilge pump ran my batteries flat on two occasions, and I had to pull them out and bring them home for charging. I don’t know how you’re defining “fully charged” but if I recall correctly I would have 13.6 volts of potential from each battery after charging on the Schumacher. I don’t have a battery level meter on my boat.
I’ve got a small solar panel and charge controller on my boat that trickle-charges the batteries. It keeps them topped up enough that I leave them on board over the winter and have the amperage to start the A4 on launch in the spring. I’ve got a pair of group 29 lead/acid batteries that I topped up with distilled water when I brought them home to recharge. Two years after running them both flat twice, and recharging them with that Schumacher SC4, they’re still giving perfect service. If I recall correctly I bought that Schumacher unit because it was relatively inexpensive.
