People who own vehicles know, or quickly learn, that they can't leave the headlights on for very long if the car is turned off, or the battery will go dead. Without the alternator providing an electrical supply, the vehicle uses battery power for electrical components. The battery actually is intended to use a quick burst of energy to start the car, not to supply ongoing power to the headlights. Knowing this, it may seem mystifying to see people camping in an RV and leaving the lights on inside for hours. A representative at a Battery Supplier Brisbane has available can explain the difference between the car-starting battery and the one that campers use for ongoing electrical power.
A deep cycle battery allows lights to stay on and also powers equipment such as a TV set and a microwave oven. The battery is continuously discharging power and being recharged. This is in contrast to the passenger car's battery that needs the vehicle to be running to recharge it, or a battery charger hooked up to it for several hours if the power supply has been substantially drained.
These devices are useful for many kinds of recreational applications. For instance, people with sailboats commonly have deep cycle batteries for ongoing electrical use. People who enjoy fishing from a motorboat may have a trolling motor in addition to the standard outboard. That equipment runs on battery power. This motor is quiet and allows the boat to move slowly through the water while the person fishes. Golf carts also run on battery power instead of being propelled by a gasoline engine. Imagine how disruptive a gas-fueled golf cart would be on the course due to noise and exhaust fumes. Golfers seeking to enjoy a quiet day outdoors would have that experience ruined.
Bigger devices function the same way for more extensive applications. An off-grid solar house, for instance, runs on these batteries, although the equipment is larger than that found in an RV or sailboat. The sun keeps the batteries charged and recharges them after a cloudy day or overnight usage. When the batteries get too low because of several cloudy days, the homeowner typically recharges them with a gas-fueled generator, although purists won't do so because this relies on another nonrenewable resource.
The batteries are helpful options for individuals who spend a lot of time in an RV or a recreational marine vessel and desire to have electrical power for convenience. A variety of brands, sizes, capacity and pricing should be considered for particular uses
