What are gel batteries?

Gel batteries are a type of battery that use a special type of silica gel to hold the electrolytes together and allow for the flow of electrons through each interior plate. They are sensitive to correct charging and can become inoperable prematurely if not charged properly.

Are gel batteries better than AGM batteries?

When compared to AGM batteries, Gel batteries are less durable, have a shorter lifespan, and are more expensive. As we’ll discuss, more and more boat owners are making the switch away from gel cell batteries. Lithium-Ion (Li-Ion)

Why do gel batteries need a regulated charging system?

Gel batteries have a gelled electrolyte that absorbs water to keep the closed system hydrated. Gel batteries and AGM batteries require a well-regulated charging system. Gel batteries are extremely sensitive to charge voltages above 14.1-volts DC at 68 degrees.

How do gelled batteries function?

Gelled batteries function by using an electrolyte that has been thickened to the consistency of petroleum jelly with the addition of a silica agent. The agent allows the electrolyte's water to bind with the acid. Once inside, the gel undergoes a chemical reaction, heats up, and liquefies.

What are the best deep cycle marine batteries?

The best deep-cycle marine batteries - AGM and gel batteries: Trojan, Mastervolt AGMs keep the lights burning. Updated April 11, 2017 The term lead acid battery usually conjures up the image of a standard flooded cell battery commonly found in cars and 80 percent of all production boats.

Are AGM batteries suitable for a boat?

AGM batteries are suitable for a boat as they can handle high electrical loads, are resistant to vibration, can be installed at any angle, are sealed, non-spillable, and are maintenance-free. Some AGM batteries last up to 2x longer than standard flooded batteries, making them an efficient and strong choice.
