For those of us who are ever in need of a 4 bank marine battery charger, it just means one thing: we have a pretty neat battery setup that may include a trolling motor battery, a starting battery, a house battery, and an additional battery.
With this kind of charger, we get to save ourselves from the frustration of having to rotate one or more bank battery charger for our four batteries. Getting this charger is a smart move compared to rotating or trying to charge a lot of batteries at the same time with just one charger.
With this type of charger, you can get all of the advantages of a charger maintainer to all of your batteries for their own individual needs. This helps in prolonging the life of your batteries, saving you more money as you don’t need to buy batteries frequently.
With the chargers we have today, they have microprocessors built into them. This controls the multiple phases of charging as well as the processes for maintenance. This includes recovery functions and desulfation that allows the battery to have a longer life as well as better performance.
These chargers also maintain your batteries during the off-season when it is unattended. This makes sure that the batteries and the engine will be ready when you want to use your boat again.
