The installation can be as simple as connecting two batteries in parallel to make one larger battery bank. If your starting battery is of the lead-acid type, stick to a deep cycle battery of the same chemistry, instead of choosing a gel or AGM battery with different charging requirements.
Marine batteries and car batteries share some common features but have major differences in design and discharge. This means that if you need a marine battery, you'll get far better results by purchasing a specific marine battery than by using a battery designed for a car.
Starting battery (Automotive battery etc) : 3-13 months. Marine Battery : 1-6 years. AGM Deep cycle: 4-7 years. Gel Cell Deep Cycle: 2-5 years.
Deep cycle batteries provide sustained energy, making them ideal for certain applications that require more than a quick start.
Some of the most common uses for deep cycle batteries include:
- Marine applications.
- Recreational vehicles.
- Materials handling, including forklifts.
- Golf carts.
- Off-grid renewable energy.
In simple terms, a car battery is a “starting battery” or “cranking battery.” Its job is to provide the necessary power to start the car's engine. Once that's done, it's job is over. Marine batteries, on the other hand, are designed to both starts an engine and provide energy for other devices aboard the boat.
Boat batteries are expensive to buy in the first place, yet they can lose most of their capacity within a couple of seasons if they are mistreated. However, if you treat them well, a set of decent service batteries can last for five to seven years. Decent batteries are expensive, yet still vulnerable to mistreatment.
Some dual purpose batteries can work for both cranking and trolling. For instance, deep cycle batteries are built to withstand many discharges and recharges while cranking batteries are not. A dual purpose battery, therefore, falls somewhere in between.
Among conventional deep cycle batteries, the flooded battery is the most common, which is similar to the standard lead acid battery in your car. The gel batteries, as the name suggests, have a gel-like substance in them and the AGM batteries consist of acid suspended in a glass mat separator.

While the motor is running, the alternator inside will easily and quickly replenish the used energy.Install tip: Choose carefully when selecting a deep-cycle battery
- Maintenance. If a site is easily accessible, then deep-cycle flooded batteries are a good choice due to their low cost and widespread availability.

- IEC testing.
- Cycle life.

The main difference between gel and AGM batteries is the charge rates. AGM batteries can handle higher charge and discharge rates than gel batteries. Gel batteries are the most costly of the VRLA batteries, but excellent candidates for projects that need a very slow deep discharge.

Charge them after every trip. If it sits for longer than a week, charge them again. Your batteries should be charging everytime you run the boat. if you run every week, you probably won't ever need to run the charger as they should be fully charged when you return to port.
Most boats with dual-battery systems use one starting battery and one deep cycle battery. Since they have lower storage capacity than comparably-sized deep cycles, we recommend them for boats with two identical batteries used interchangeably for starting and house electrical loads.
Advantages: Lighter and smaller than flooded lead-acid batteries for the same capacity. No regular maintenance or topping-up required. Low internal resistance allows very fast charging, with reduced energy loss.
I understand that a deep cycle battery shouldn't be charged from a typical car alternator as it tries to dump as much amperage to the battery as possible and doesn't do the charge staging and TLC that a deep cycle battery requires, and puts out more (less?) voltage than is acceptable for charging them.
While the car battery provides a surge to start your car, the AGM deep cycle battery is not designed to be used as a cranking battery as the draw needed to start up is too high to be sustained. As a general rule of thumb, the heavier the deep cycle battery, the thicker the lead plates, the longer it will last.
That's where deep cycle marine batteries come in. One key is plates: It has fewer, thicker plates allowing the battery to provide continuous power output over long time periods. Deep cycle batteries can be entirely drained and recharged many times over, cranking batteries can't.
Deep cycle batteries are designed to be discharged down as much as 80% time after time and have much thicker plates. The major difference between a true deep cycle battery and others is that the plates are SOLID Lead plates - not sponge. The golf cart battery is quite popular for small systems and RV's.
Yes, a deep cycle battery can be used to start your motor in a pinch, but a two- or three-battery system is highly recommended to separate the engine battery from the accessory (house) batteries.
Deep Cycle batteries provide a greater reserve capacity, but cannot deliver as many peak CCA's (cold cranking amps). Starting Batteries are made to provide high power for higher amp, more frequent short draws, and limited long term discharge.

Of course you can use a battery with a higher CCA and amps but make sure your truck supports such a big battery. Bigger batteries need more space, if you have some really good vacant area in your vehicle then you can go for it. With a bigger battery you'll get long lasting performance and efficiency.

It's actually an old misconception among boaters that car batteries can be used for boats. In reality, while a marine battery may be able to power a car for both short-term and long-term use, a car battery won't be able to do the same.
In simple terms, a car battery is a “starting battery” or “cranking battery.” Its job is to provide the necessary power to start the car's engine. Marine batteries, on the other hand, are designed to both starts an engine and provide energy for other devices aboard the boat.
Starting Batteries and Battery Ratings
This deep-cycle marine/RV battery is rated for 500 MCA (marine cranking amps) and 80 amp-hours. The 140-minute reserve capacity indicates the number of minutes a battery can deliver 25 amps of current without dropping below 10.5 volts.Hulking V-8 engines will need a higher CCA battery than a 4-cylinder compact car; however, most OE specifications will require a minimum of 400 to 500 CCA to be able to turn over the starter.
If you want to use marine batteries in your truck, go ahead, it will work just fine. If you want to use deep cycle batteries you might want to reconsider. The main difference in the three types is the thickness of the plates and power output. A starting battery uses lead sponge type plates, lots of surface area.
Marine batteries are designed specifically to meet the needs of a modern boat. They're stronger, heavier and more suited to the unique needs of a boat with an inboard or outboard motor. Take good care of them, and they'll last for several years of continuous use.
