Boat Battery by OZZYPOWER

A boat’s electrical system starts with a battery that will supply the electricity for the boat. The system is usually 12 volt DC (direct current) but can be 6 volts, 12 volts or 24 volts, depending on how many and what type of Boat Battery the system is designed for.

A boat’s wiring is a two-wire system. One wire goes from the battery to the light or instrument to be used and a second wire returns to the battery from the light or instrument to complete the circuit. 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. Therefore, each item used will have two wires, one to get power to it, and one to return the electricity. This is a very simple explanation of how a boat is wired.

Marine batteries were designed for boat use and have thicker plates and a solid structure to withstand vibrations and hammering. However, marine batteries are more expensive than auto batteries. This may make it tempting for some boat owners to buy a vehicle battery instead.

The battery capacity or how much electricity it can produce is given by the voltage and amps listed on the battery. The group size is the physical size of the battery, the height, width and length. This lets you get the right size that will fit in the space you have for the battery. The battery designation will be Deep Cycle or Cranking.

A deep cycle battery will put out a steady current over a long time. For example, a Cranking battery can put out a high amount of current for a short time to crank a motor over to start it, but it will not last a long time under continuous use as a deep cycle can. Some batteries, like AGM batteries, are often designated as both and are dual-purpose batteries.

Marine Cranking Amps, Cold Cranking Amps and Reserve Capacity data is also often given. These numbers tell you they respond under a load 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 are required to start the motor.

Starting batteries plates are thinner and more extensive, providing additional surface area for large current bursts. The downsides to the structure include the fragility of the plates in high-impact environments and the fact that the beginning batteries are unable to withstand deep sparks, which can reduce their lifespan.
