Choosing a Boat Battery Charger

When selecting a boat battery charger, you’ll first want to consider the boat battery type and battery capacity. Then, you’ll want to consider the purpose of the battery. The types of chargers designed to maintain boat batteries during the offseason (often referred to as marine battery tenders) can be different from the types of chargers designed to quickly recharge your boat battery during peak season.
