Deep cycle batteries are a specialized type of power cell that is created to be able to run very low on power supply and not a malfunction. In fact, if a deep cycle battery only serves slightly and then the charge overcome though, this is the best way to ruin this type of battery.
The deep cycle of the term just means that they take a power cycle in depth and run to almost empty before they have to be loaded and that’s how they are meant to be used. Charging them is not difficult but you have to do it correctly.
Charge a Deep Discharge Marine Battery
- Install your charger, the 12-volt battery charging system. This charger is plugged into your electrical system and permanently attached to the battery. You must be connected to a 120-volt service when the boat is connected to a power line of earth.
- Remove and install a new battery when replacing an old one. If you are having difficulty, maintaining a charge with your deep-cycle battery, recharging it will not correct the problem. If the battery does not hold a charge, it has survived its useful life and must be replaced. Connect to a new battery at the negative (black) terminals with the battery cables and positive (red). Attach the same color charger to the same color.
- Run the battery charger on your deep-cycle battery according to the instructions of the device you are purchasing. All permanent charging systems are designed to stay on battery full time and some monitor the battery for power levels and add charges when needed.
- Disconnect the charging system from the electrical connection when not in the port or connected to an electrical connection.
- Periodically check the battery with a tester meter or battery voltage to be sure that it is maintaining a correct charge. Be sure not to forget these batteries are designed to sink at a reduced rate before recharging, and if this is not done regularly the battery will no longer be a full charge.
Some Dangers of Charging a Deep Discharge Marine Battery
Deep-cycle marine batteries can be dangerous if not charged and maintained properly. Some potential dangers include:
- Overcharging: Overcharging a battery can cause it to overheat, which can lead to damage or even a fire.
- Sulfation: If a deep-cycle battery is not used for long periods of time or is not charged properly, lead sulfate crystals can form on the battery’s plates, reducing its capacity and shortening its life.
- Explosion: An explosion can occur if the battery is overcharged, over-discharged, or damaged.
- Gassing: Gas from the battery can be explosive if the battery is overcharged.
- Corrosion: Marine batteries can corrode if not maintained properly, which can lead to damage or leakage.
It’s important to follow the manufacturer’s instructions for charging and maintaining a deep-cycle marine battery to minimize these risks.
To charge a deep discharge marine battery, it is important to use a charger specifically designed for marine batteries, as these batteries have different charging requirements than standard car batteries. The charger should be set to the appropriate voltage and amp setting for the specific type of marine battery being used. It is also important to monitor the charging process and not overcharge the battery, as this can damage the battery and reduce its overall lifespan. Additionally, it is also recommended to charge the battery in a well-ventilated area and to wear protective gear, such as gloves and safety glasses, to prevent injury from acid or electrical hazards.
