Review on Schumacher SC1359 Automatic Battery Maintainer by Tony Hanson

I bought this item to charge my boat's batteries. Prior to this purchase, I purchased a similar charger model from a local parts store. I am very satisfied with the performance of this charger. This charger from Amazon has the same specifications. I was hoping to be able to charge both batteries at the same time. A charger from a parts store will typically charge the battery in two to four hours, depending on usage. It takes 12 to 24 hours to fully charge this charger. I've experimented with these chargers a few times and hooked up this Amazon charger to the battery that needs charging the least. Every time I get the same result, this charger takes significantly longer to fully charge the battery.
