Last Updated: July 5th, 2022 | By: Gina

Getting stranded without power can be one of the most difficult experiences. On a boat, this could be a helpless feeling when you are right in the middle of a planned trip. It is hard to imagine one’s plight with no power or the possibility of charging the battery and restoring the power.

A deep cycle battery is often the battery of choice due to the power ratings and the build quality that makes it suitable for long trips. However, it is necessary to take care of the deep cycle battery and most importantly know how to juice it up with a battery charger.

Ways To Charge Up A Deep Cycle Battery

It is possible to charge a deep cycle battery through two different methods. The versatile battery permits you to charge it either on the boat or you could also remove it from the boat and juice it up. It is important to match the battery with the right kind of charger.

Recommended chargers are always the best options, as this ensures that the battery or the charger will not end up damaged. With a lot of money going into the boat, it pays to ensure that quality is not compromised in the search for a cheaper alternative.

Regardless of the methods chosen for recharging the battery, it is essential to follow certain instructions that are common to both. For instance, the charging needs to be carried out in a space where there is an outlet to vent the gaseous discharge. Similarly, basic precautions that are necessary during charging are the same for both types of charging.

The primary difference is the location of the charging, whereas all the precautions and instructions for charging will remain the same. Charging your deep cycle battery on the boat will save you the time and effort that is required for removing it and reinstalling the battery back to its spot. The advantage of charging a battery away from the boat is the advantage of getting it done on terra firma with the right kind of gear and terminals necessary for carrying out the recharge.

To begin with, it is essential to understand the existing charge levels and the amount of time that is necessary for topping it up. The most important aspect that needs to be followed is the need for ensuring that the manufacturer’s instructions are followed diligently. The technical manual and specs are important documentation and should not be ignored.

Before attempting to charge the battery, it is essential to wear the right kind of protective gear. The next step that needs to be performed for charging is to disconnect all systems that are plugged into the deep cycle battery. This is necessary to prevent damage to the systems that may occur in the event of a sudden surge in power.

Precautions that need to be taken prior to charging the battery with a deep cycle battery charger are the need to ensure that gaseous discharge has a clear outlet to leave the building. Begin the process by clamping the red clip onto the positive terminal and the black clip on the negative terminal. Both the terminals are indicated with a positive or negative symbol that can be clearly seen.

Finally plug into the power socket that is rated at 110-120 volts. Once the charge full indication is on, turn off the charger and then disconnect the power supply. In models where the auto cut-off is not a standard feature, you need to monitor the levels to prevent overcharging. Reinstall the battery back in the boat, and double-check before connecting the systems.

Typical Discharging Rates

Deep cycle batteries for marine use have a lesser rate of discharge than the regular marine batteries commonly used in boats. While deep cycle batteries used generally discharge up to 85%, marine batteries only discharge up to 50%. However, it is important to know that deep cycle batteries have the capacity to recharge fully up to 100 percent despite the discharge of 80 or 85 percent.

Individuals with less experience in handling deep cycle batteries for marine use, need to get accustomed to the slight differences. This is basically about the differences in functions and the manner in which the batteries charge. As the discharge rates are high, individuals typically tend to view the batteries differently.

Charging your deep cycle batteries is of great importance, especially for batters used on boats. Without power, boats become the most difficult and sometimes dangerous vessels. Battery power is of great importance for enjoying outings and the last thing that you would ever want to happen is to find yourself on a boat without power. While the idea may seem romantic, it is not suitable for long stretches, unless you are participating in a reality tv show.
