Types of Marine Battery

Chemical marine batteries can be classified into 3 types, flooded batteries, gel batteries and Absorbed Glass Mats (AGMs). They are rated on the basis of energy output which is measured in ampere hours.

This output along with the lifespan generally determines the batteries’ price. Overall, the way you utilize your boat, the kind, and size of your boat and your budget are the major factors to consider while purchasing the battery.

Flooded Battery

Also known as wet batteries, these batteries are the cheapest and most popular type of marine batteries. These batteries require regular inspection and filling up with distilled water.

The flooded batteries are believed to self-discharge at a rate of 6-7%, which is greater than the AGM and gel batteries.

Gel Battery

The gel employed in gel batteries includes a mix of pure water, phosphoric acid, fumed silica and sulfuric acid.

It is slightly viscous which stops leakage from the battery if it is tipped or when the case suffers damage.

Absorbed Glass Mat (AGM) Battery

These batteries are built with glass mat separators which are saturated in an acid electrolyte solution.

AGM batteries possess improved vibration and shock protection in comparison to gel and flooded batteries. Though the most expensive, their quality is excellent.

When You Need To Get a New Marine Battery

A new marine battery is needed by the boat when its battery gets discharged. The new battery may be required to start and run your engine.

You may then be required to purchase a new battery to fire the ignition and supply fuel through the electronic injectors.

Buying Guide For Getting New Best Marine Battery

A marine battery is a vital unit of direct or back up power for boats or other marine types.

While choosing marine battery one should consider its weight because if you need to transport the battery often, then a marine battery weighing 20 to 50 pounds would be ideal. If regular transportation is not required then opt for 70-80 pounds of battery weight.

The kind of battery

The battery type whether Starting (Cranking ) or Deep Cycle which is used in marine and golf cart applications.

The deep cycle batteries contain thicker plates and can withstand multiple discharge cycles. The Absorbed Glass Mat (AGM) and Wet Cell (flooded) are different lead cell battery versions.

Reserve capacity

While procuring a deep cycle marine battery it is vital to consider its reserve capacity rating. RC rating denotes the time in minutes the battery discharges up to 10.5 volts by delivering 25 amperage discharge at 80 degrees Fahrenheit.

It indicates the time during which the battery will continue to operate basic accessories in situations of an alternator or generator failure or when the key is off. The higher the RC rating of the battery, the longer it will power up appliances.

The top quality marine batteries bear an RC rating of 180 minutes and the inferior ones have up to 35 minutes. The average quality marine batteries contain 60 to 90 minutes RC ratings.
