The Best Deep Cycle Marine Battery

You need the right battery for your boating escapades – in almost every instance, this will be a deep cycle marine battery. They can run for long periods without causing damage and typically come in three types: flooded lead-acid, absorbent glass-mat and lithium-ion batteries. All three have different pros and cons, which influence the one that works for you, so you must know which will work best with your boat.

1. Flooded Lead-Acid Deep Cycle Marine Batteries

Flooded batteries are the standard in many industries, relying upon an electrolyte acid that must be regularly measured and ‘topped’ with distilled water to work best. They are usually cheaper than AGM batteries, but they require frequent maintenance, and rigorous activity can damage them. On top of this, extreme weather can even freeze the electrolyte solution. That is especially risky if you plan to boat through cold waters, as your unique environment might not fare well with a flooded battery.

2. Absorbent Glass-Mat Deep Cycle Marine Batteries

AGM batteries are relatively free of the complex maintenance needed to look after flooded ones. The titular glass mat works by soaking the acid between lead plates, storing it in a dry form. This allows it to deliver its full capacity with stronger overall performance and durability. In addition, they have a quicker charging time and a longer lifespan. They were developed for the military originally, making them a robust solution for boating and other marine needs.

3. Lithium-Ion Deep Cycle Marine Batteries

Lithium-ion batteries forego acid and plates and instead use lithium salt – these batteries are maintenance-free thanks to in-built management systems. Their increased efficiency allows them to charge faster than the other models while sustaining long discharges better. They also weigh less than other batteries, which makes them a great investment if you are concerned about your boat being weighed down.

You have to choose the best deep cycle marine battery for your vessel, and it appears that AGM or lithium-based batteries will offer the solution you need. At Lifeline Batteries, we can supply your boat with AGM or lithium-ion deep cycle power, allowing it to last as long as you need in any environment.
