Batteries and Chargers for a Boat

Basics to Finding the Right Battery Charger

The most fundamental component of your boat's electrical system is the battery, which is why we carry a huge selection of marine-grade battery chargers, battery boxes, trays, ties downs, switches, battery isolators, terminals, inverters and more. ... read more Some of the competition may offer non-marine-grade batteries and components; don't be fooled! When you shop at iboats.com you can be confident that the battery parts and accessories you buy are made by brands such as Ancor, ProMariner, Xantrex, Guest, Minn Kota and SeaSense, which manufacturer products specifically designed for your boat and it's harsh and wet marine surroundings.

With so many battery chargers on the market and  a massive variety of specs and features, finding the right charger for your boat can seem quite daunting.

The first step will be to do is qualify the attributes of the battery charger you plan to purchase.  This includes determining the type of battery charger you'd like to use, how many batteries you want to charge at once (banks), amperage you'd like batteries charged at, AC input voltage, DC output voltage, and battery compatibility.  The fact that features & attributes are mixed-and-matched to form specific products means there are a lot of options, but most features and attributes have little variations, making the decision making process simple.

For example if you limit your boating to the USA, you know you'll need a charger that provides an AC input voltage range that includes 120 volts.  Have 3x lead-acid 12VDC batteries?  You'll need a 3-bank 12v battery charger compatible with lead-acid batteries.

For a more thorough break-down of the standard features and options used by most onboard boat battery chargers, check-out our battery-charger guide at the bottom of this page.
