Ship's electrical system from the battery start, the battery will power the ship. The system typically 12 volts DC (direct current), but may be 6 volts, 12 volts or 24 volts, depending on the number and type of cell system design. For this article, the system in question is a 12-volt system.
Wiring ship is a two-wire system. A wire, the other wire from the battery to the lamp or to return the instrument to be used from the battery to the lamp or instrument, to complete the circuit. In the current system, the current flow in one direction only. Lamp current flows from the battery, and then flows back into the battery. Each has its own article using two wires, one for its power supply and one for return power. This is a very simple explanation of how the boat wiring.
Onboard battery used are three basic types. They are similar to a car used in wet batteries, gel batteries and absorbent glass mat batteries or AGM. All of these types are rechargeable. How much charge the battery capacity may be determined by the voltage and amperage generated number listed on the battery. Group size is the physical size of the battery, the height, width and length. This way, you can find the right size for battery space. Battery entitled "deep cycle" or "Start."
Deep cycle battery can output a stable current over a long period of time. Start-up battery can be issued in a short time large amount of current to the starter motor starter motor, but in the case of continuous use (e.g., deep cycle), the motor will not last long. Certain cells (e.g., AGM batteries) generally designated BOTH, and are combined with the battery. Often provides marine start amps, reserve capacity and cold start amps data. These numbers tell you that they respond under load conditions, and allows you to compare the same physical size batteries. Marine motor boat will determine the starting amperage required to crank the motor.
Wet cell battery generally has an openable and add water. When used in the battery heat, the water was evaporated therefrom. Battery must always be covered with the liquid acidic acid battery cell or battery. Acid does not evaporate, but the water does not evaporate, so you need to add water on a regular basis. These wet cell types must be kept horizontal, or acidic water mixture exhausted. If the acid leak out, it will destroy a lot of things. You can use a sealed, leak-proof wet battery, so as not to add water. AGM and gel cell battery is sealed and leak-proof. AGM battery can be stored in any position, and the discharge rate of the battery is idle AGM type battery and better than the wet gel battery.
The battery will have to bear the load will determine the type of marine battery required. If it is used to start the motor and run only some appliances, the battery may start to work. If it is used as a trolling motor and other power electronic devices, and produces a constant drain for a long time is required deep cycle. AGM dual battery are popular it is because it can be a good start and deal with the load. Another reason for their popularity is that they are sealed and may be stored in any position. Annual General Meeting of choice for today's maritime industry.
May be connected together in two or more batteries for more power. If used with two, they must be the same. If the battery is different ampere rating would damage the battery. How to connect the battery together is very important. If the two are 12-volt battery, and the two + (positive) terminals are connected together, and two - (negative) terminals are connected together, and the side of the battery are - between the output side will remain 12 volts, but the output of the amplifier will be doubled. This is called parallel connections.
If the two are connected together, so that on reaching the other + a - and are connected to a power supply consisting of a battery and another battery + terminal - terminal, the output is 24 instead of 12 volts, amps and remains change. It's like two stacked battery in a flashlight. It is said that these are connected in series.
6 volt battery usually has a higher ampere rating than the 12 volt battery of the same size. Connecting in series two 6-volt battery, you can obtain a 12-volt power, which has a greater current than a single 12-volt battery amperage. Both do not have a 12-volt battery as hard as the same job done. This is the reason why most golf cart 6-volt battery life. Such options have really great.
There are different types of battery charging system. Best multistage automatic charging system. Since marine batteries more expensive than on-vehicle battery, so this type of battery can be charged without overcharging. Most people feel the type of battery you have, select the correct charging method. This will help extend battery life.
You can use car batteries on board, but the battery can be manufactured for the marine industry to provide better service for you. They are made according to the load requirements of the ship, they are often sealed and leak-proof, and generally high load dual-purpose deep-cycle type. AGM battery is the choice of boaters. Compared with the conventional batteries, which provide high power and low internal resistance, and their life is twice that of conventional batteries.
