Battery Type: The three main types of deep cycle batteries are flooded lead-acid, AGM, and lithium-ion. Flooded lead-acid batteries are cost-effective and often used in larger systems, but they require regular maintenance. AGM batteries are sealed and maintenance-free, offering better performance in a smaller size. Lithium-ion batteries, while more expensive, provide longer cycle life and faster charging times.

Capacity: Battery capacity is crucial for understanding how long your inverter can run appliances. It is measured in amp-hours (Ah), indicating the total amount of energy the battery can store. A higher capacity means that the battery can supply power for extended periods, which is essential for applications like off-grid living or backup power systems.

Discharge Depth: The depth of discharge (DoD) is vital for maintaining battery health. Most deep cycle batteries can handle a DoD of around 50% to 80%, meaning you should only use half or less of their total capacity to prolong their lifespan. Understanding DoD helps you plan your energy usage effectively.

Charging Time: Charging time varies significantly between battery types. Lead-acid batteries can take several hours to charge fully, while lithium-ion batteries can achieve a full charge much more quickly. This efficiency makes lithium-ion batteries a popular choice for systems that require rapid charging.
