Keeping the boat's battery banks charged and healthy is crucial for the performance of its electronics or electric appliances. Besides, it's important for a smooth engine start. Marine batteries can get electricity from an alternator or charger. The latter doesn't rely on a running engine and is sometimes combined with an inverter in a single device providing you with a source of AC current for a laptop, TV, or other equipment. There are numerous models of marine chargers having different characteristics, and they have to be properly selected according to the battery type, capacity, and some other factors.
It's generally recommended to choose a charger whose rated amperage is about 10 or 15 percent of the combined batteries' capacity measured in ampere-hours. In our store, you will find first-class marine chargers designed for a different number of battery banks, and most of them feature advanced microprocessor technologies to send more power to a weaker battery and provide relatively quick yet smooth charging for greater efficiency and longer lifespan. Supporting different voltage, many of our chargers are fully automatic and compatible with all the existing battery types including lead-acid, AGM, and gel models known to have certain nuances related to charging.
