How to Hook Up Marine Batteries
Batteries provide the juice that any car or boat must start and help maintain the vehicle's electrical system at the same time. There are many different types of batteries out there, including marine batteries. Although they seem slightly different, marine batteries perform the same function as ordinary batteries, and they can be hung in almost the same way. It should only take a few minutes to connect and mount a marine battery.
Hook Up Marine Batteries
- Unlock the boat's original battery using the 3/8 "ratchet and socket. This will allow the battery to be removed from the boat. There are two terminals on top of the battery, one marked (+) positive, and one marked (-) negative.
- Unscrew the wing screws on top of the battery using your hands. If the wing nut is corroded and the nut does not come off easily, use a wrench to depress a wing of the wing nut and turn counterclockwise. Next, place the wiring on the sides, making sure to note which wire is positive and which is negative. Remove the old marine battery.
- Place the new battery in the same location as the old battery. And tighten it using the factory supports and a 3/8 inch ratchet and socket. Reconnect the wiring to the appropriate terminals, placing the positive wire on the (+) terminal and the negative wire at the (-) negative terminal.
- Tighten the wing screws on the terminals using your hands. If you cannot get them tight enough by hand, use the adjustable wrench to strap on the wingnut.
How to Install Marine Batteries
Marine batteries are rather large units, heavy. They are lead-acid batteries that are used to store large amounts of electricity to run the boat starter and other DC loads (DC). The 8D-size batteries the most popular size. These batteries are about 24 inches long and weigh about 180 pounds. The battery boxes can be broken, and the batteries ruined if the batteries are allowed to move freely as the boat and roller pitches. Impact shock and vibration can also cause internal damage to reduce the capacity of the battery. Marine batteries must be securely strapped to protect them.
Install Marine Batteries
- Use an assistant to help you lead to the battery. Place the battery in its desired location. Arrange the lashing restraint straps. There should be two straps per battery.
- Drill a pilot hole through the mounting surface of the battery. Install the retainers with the mounting screws and a screwdriver.
- Thread the lashing straps through the retainers. Lay the strap ends on the wise width and set the battery in position. Bring the strap thus ends on top of the battery and engage the strap tails in the buckles. Tighten the straps firmly and lock the strap buckles.
Tips and Warnings
Battery straps should be enough to carry the weight of the battery strong, while inverted, for at least an hour. This should allow a reasonable amount of time to recover from being spilled or capsized.
How to Install Marine Batteries in a Series
Battery-powered accessories on a boat often work on something other than a 12 volt power source. For example, trolling motors often need 24 or 36 volts. The most readily available batteries do not usually come in these tensions; learn how to connect standard voltage batteries in series to achieve the desired voltage on your boat.
Install Marine Batteries in a Series
- Use batteries of the same chemistry and voltage to get the best results when connecting batteries in a series.
- Arrange the batteries so that the positive terminal of one battery is next to the negative terminal of the other.
- Connect the batteries by attaching a connecting cable between the negative terminal of one of the batteries and the positive terminal of the other. For more than two batteries, just continue the pattern to connect them in this way.
- Attach the positive and negative wires of the device you are planning to power the corresponding positive and negative terminals on one of the batteries. Make sure that you connect the two wires of the same battery.
How to use Optima Marine batteries
Optima marine batteries are made for the use of boating. These batteries are also known as DC batteries, which means deep cycle. A marine battery starter will turn on the trolling motor and the lights and radios of the boat. An Optima battery attaches to the trolling motor using red and black cables. Before attaching and using the battery, make sure that the cables of the motor boat are free from corrosion.
Use Optima Marine batteries
- Open the battery compartment of the boat. Inspect the battery cables for corrosion. If there is corrosion, wash them with a toothbrush soaked in a cola-based soda. The acid in the cola decomposes from the corrosion caused by the acids of the battery.
- Pop the Optima battery terminal caps to expose the terminal connections of the metal battery. Connect the red boat engine cable to the red terminal of the Optima. Connect the black cable to the black terminal. Use a wrench to tighten the terminals.
- Turn on the boat's lights or radio to test the battery and connection. Close the battery case and try to start the motor to test the battery.
- Clean the battery terminals and cables every two to three weeks to keep the connection secure and productive.
The difference between a Deep & Marine battery cycle from
Starter and deep cycle batteries are designed for different applications and conditions. Although both can be used in boats, starting batteries need to be used for starting the engine while deep cycle batteries offer less starting capacity.
The difference between deep cycle and starter batteries is found in the construction of the lead plate. Deep-cycle batteries have solid lead plates that are much thicker than lead sponge plates in starter batteries. Sponge construction in starter batteries provides a larger surface area, resulting in more startup amps. A at startup are the amount of a current battery can produce at 32 degrees Fahrenheit. Plus starting Amps a battery has, the easier it is to start the trolling motor.
The lifetime of a battery depends on how it is used. If a starter battery is deep discharged, or discharged up to 20 percent of its charge, it typically lasts between three months to one year. A deep-cycle battery can last between four to eight years in the same deep-cycle application. Deep-cycle batteries must be oversized by about 20 percent so they must be used to start a trolling motor.
