Deep cycle and marine batteries are both usually used for a kind of applications, ranging from common energy sources to boat engines and electronics to small-scale renewable energy applications. However, if the batteries are not properly serviced, they will deplete quickly. In some cases, you may need a dead battery to be replaced if you have lost your ability to hold the charge. There are several ways to ensure that your batteries are fully charged and taken care of, one of the most common of which involves the use of a drip charger. #1 Install a drip charger on your boat to keep the battery fully charged marine. Drip chargers can be connected to a power source, if one is available, or you can use solar battery chargers if you are only going to use the boat intermittently. Solar chargers work best if they can sit for several days and charge the battery and do not charge it quickly in a few hours. Solar chargers should be of a size based on the battery voltage they charge. #2 Place the solar panel as far as possible direct sunlight if you are using a solar cell connected to a drip charger device (sold commercially as a product). Conventional solar theory suggests solar cell fishing in the same degree as its latitude plus 15 degrees in winter and 15 degrees in summer. #3 Clip the electrodes into the marine battery terminals once the solar cell is correctly positioned. Look for an indicator on the drip charger, such as a light or the display indicating that it is properly connected to the LED battery. Some drip chargers, solar or otherwise, will also tell you when the battery is fully charged. Load controllers #4 Install a charge controller connected to a generator if several marine batteries are being used and the batteries are depleted on a regular basis. The charge controllers are designed to direct the flow of electricity to and from the batteries in a way that prolongs their useful life by maintaining the charges properly and avoids against overcharging. #5 Connecting the cables to the input terminals of the load regulator, allowing a power source, such as a turbine, solar windmill or generator to send electricity to the load regulator. The cables at the entry point must be sized depending on the size of the current going to the batteries of the power generation source. #6 Attach the same size cables with buttonhole is attached to the ends of the cables so they can connect to the marine battery or battery bank. Whenever a load controller is used, it is also advisable to install a discharge load to the secondary output terminals of the load controller. Dump loads are commonly used in renewable energy applications such as a heat sink that dissipates additional electricity that deviates from the edge of the charge controller battery.
