• Deep cycle lead acid batteries are less expensive and allow for repeated charging, however they are heavier than other battery types and require routine inspections and maintenance.
• The life-cycle of deep cycle lead acid batteries can have a shorter life than other battery types.
• Absorbent glass mat or AGM batteries feature improvements over deep cycle lead acid batteries.
• Since AGM batteries are sealed, they are maintenance free and spill proof. They also charge faster and last longer.
• AGM batteries are more expensive than other deep cycle batteries.
• Lithium ion batteries are now available for deep cycle applications.
• Lithium ion batteries are equipped with an internal battery management system for safety.
• Almost double the power and lighter than other batteries, lithium ion batteries offer a long life cycle.
• Keep in mind that lithium ion batteries require a specific type of charger and don’t handle well in extreme temperatures.
