                                                                  Common Charging Types:
                                                                  • On-board battery chargers are battery chargers that are mounted to the boat. These chargers use an AC power source (most commonly a standard wall-outlet in the garage or shorepower station), with the charger transferring the power into the DC current your batteries need
                                                                  • Battery Maintainers & Trickle Chargers are terms used to describe a battery charger that provides a slow and steady charge. The most common use of these chargers are to prevent a battery from dying when it's not in use for extended periods of time.
                                                                  • Charging Relays are used to route and manage alternator generated current. Charging relays also have 'battery isolators', which isolate the charges to each battery (circuit). Battery Isolators have the same function as charging relays, but usually don't include the management of the alternator-generated current.
                                                                  • Battery to Battery Chargers are devices used to transfer current from one battery to another


                                                                  Battery Banks:
                                                                  Each battery you charge will connect to one of the battery chargers banks. If you need to charge 3 batteries at one time, you will need a battery charger with a minimum of three banks. It's a good idea to get a charger with the number of banks you foresee yourself using during the lifetime of the battery charger.

                                                                  Output voltage rating:
                                                                  Most Battery Chargers are rated for 12v batteries, though 24, 36v, and 48v are not uncommon. Some battery-chargers have the ability to charge multiple ratings of batteries. Simply choose an option that is rated for your batteries voltage rating.

                                                                  Input voltage ratings:
                                                                  Voltage ratings are measured in ranges, but tend to revolve around 120v and 220-240v, the most common voltage outputs world wide. In North America, you'll want to pick an option that includes 120v in it's range. Many Chargers are rated to cover AC out put worldwide (100-250v); a wise choice for the avid traveler

                                                                  Amperage rating:
                                                                  Higher amp ratings will mean a faster charge, and are commonly rated by total amps, using the sum of amps provided per bank. For example, a 3-bank charger that provides 5 amps per a bank is rated at 15 amps total. However, not all banks have the same output. For example the ProMite on-board battery charger by ProMariner includes an option that provides a total of 13amps using three banks; 2x banks are rated at 5amp, 1x bank is rated at 3amps. This would commonly be written out as '5/5/3'

                                                                  Battery compatibility:
                                                                  Make sure to pick a battery charger that is compatible with your type of battery. Most chargers will work with standard lead-acid (wet cell) batteries and some chargers are compatible with almost all battery types used in the marine industry. Regardless, verify the charger is compatible with your battery type.

                                                                  Features:
                                                                  There are many features to pick from when selecting a battery charger. Most will come standard with an automated 3-stage charging system to provide efficient charge & prevent over-charging, as well as feature a rugged construction designed to withstand the ruggedness marine environment.


                                                                  ***Notice the 'Refine Search' feature on the sidebar. It will allow you to quickly filter down to the product options that will work for your boat's needs and spend more time on price and feature comparisons.
