Are Car Batteries More advanced than Boat Batteries?

A boat’s electrical system starts with a battery that will provide you with the electricity for the boat. The device is usually 12 volt DC (direct current), but can be 6 volt, 12 volt or 24 volt depending on how many and what type of batteries the device is designed for. For this article, the device discussed is a 12 volt system.

A boat’s cabling is a two line system. One line goes from the battery to the light or instrument to be خرید وایا باتری used another line returns to the battery from the light or instrument to complete the signal. In a Direct Current system the electricity flows only in one direction. The electricity flows from the battery to the light and then back to the battery. Each item used will have unique two wires, one to get power to it, and one to go back the electricity. This is a very simple explanation of how a boat is wired.

The batteries that that are utilized on a boat are of 3 basic types. They are a wet cell battery similar to the type used in a car, a gel cell battery and an AGM or Absorbed-glass sparring floor battery. All of these types are standard rechargeable. The battery capacity or how much electricity it can produce is given by the voltage and amps listed on the battery. The group size of is the physical size of the battery, the height, width and length. This lets you get the right size that will fit in space you have for the battery. The battery designation will be Deep Cycle or Cranking.

A deep cycle battery will put out a stable current over a long time. A Cranking battery can put out a high amount of current for a few months to prank a motor over to start it, but it will not have longevity under continuous use like a deep cycle can. Some batteries, like AGM batteries, are often designated as BOTH and are dual purpose batteries. Underwater Cranking Amps, Cold Cranking Amps and Reserve Capacity data is also often given. These numbers tell you they reacts under lots condition and it lets you compare batteries of the same physical size with each other. The boat motor on the boat will determine what cranking amps must start the motor.

A wet cell battery usually has cells that you can open and add water to them. When the battery gets hot under use, water evaporates from them. The cells should have the water acid liquid inside them within the cells or the battery drops dead. The acid doses not evaporate out, just the water, so water needs to be added regularly. These wet cell types must also be level or the acid water mixture will come to an end. The acid can destroy many things if it leakages out. You can get sealed, trickle proof wet cell batteries to avoid having to add water. Gel Cell and AGM batteries are sealed and are trickle proof. An AGM battery can be stored in different position and the discharge rate of the AGM type, when it sits unused, provides multiple advances over the wet cell and gel cell batteries.

Force the battery will have on it will determine the type of underwater battery that is needed. If it is to be used to go into a motor and run just a few electric items, a cranking battery will work fine. If it will be used to power a trolling motor and other electronics industries, creating a constant draw for an extended period of time, a deep cycle will be needed. AGM dual purpose batteries are becoming popular because the can handle both starting and loads well. Another reason they are popular is that they are sealed and may be stored and used in any position. The AGM’s are the first choice in the underwater industry today.

Two batteries or more can be simply hooked together to get more power. If two are used together they have to work same. If the amp rating differs from the others between the batteries one will be damaged. How you hook the batteries together is important. If both are 12 volt batteries and you hook both + (positive) terminals together and hook both : (negative) terminals together, the output between the + side and the : side of the batteries will still be 12 volts, but the amp output greatly improves. This is called wired in parallel.

If you line the two together so your + on one goes to the : of the other and then you connect the things you power to the free + fatal on one battery and the : fatal of the other battery, the output will be 24 volts not 12 and the amps stays the same. This is like two batteries stacked very quickly light. These are reported to be wired in series.

A 6 volt battery usually has a higher amp rating then the 12 volt battery of the same size. By cabling two 6 volt batteries in series you can get a 12 volt power supply that has greater amperage then the single 12 volt battery can give. The two don’t need to act as hard to do the same job as the one 12 volt battery does. This is why most golf carts use 6 volt batteries. It is nice to have options like that.

There are different types of battery charging systems available. An automatic multistage charging system is best. Because underwater batteries are more expensive your car batteries, this type will charge the battery without overcharging it. Many sense the type of battery you have and will pick the correct charging method. This will help battery last longer.

A car battery can be used on a boat, but a battery designed for the underwater industry can give you better service. They are made to match force requirements of a boat, they normally are sealed and leak-proof, and are ordinarily a dual purpose high load deep cycle type. The AGM batteries are the boater’s choice. They provide high power with very low internal resistance compared to conventional batteries and they have 2 times the actual of conventional batteries.
