Charging Deep Cycle Battery – Everything Explained

Charging deep cycle battery can be perplexing for new users. Therefore, we are bringing a brief content on the charging procedure of the battery. But, on the first hand, we have to clarify what a deep cycle battery is and some of its unique features. Deep cycle battery leads to sustain power for a long time, and it gives the same heavy-duty even at eighty percent discharge. That is why heavy vehicle drivers and anglers prefer deep cycle batteries. 

Let’s get to our main point, charging methods of deep cycle batteries to reduce your hassles. 

What is a Deep Cycle Battery and How Do I Choose One?

A deep cycle battery is a type of battery that is specifically designed for use in marine and recreational vehicles, where it is used to power electronics and accessories. Deep cycle batteries are designed to be discharged and recharged repeatedly, making them a reliable and long-lasting power source.

When choosing a deep cycle battery, it’s important to consider the size and capacity of the battery, the type of battery, and the specific power needs of your boat or vehicle. The size of the battery refers to its physical dimensions, including the length, width, and height. The capacity of the battery is typically measured in amp-hours (Ah) and refers to the amount of energy the battery can store. There are several types of deep cycle batteries to choose from, including lead-acid, lithium-ion.

To choose the right deep cycle battery for your needs, consider the size and power of your boat’s electronics and accessories, as well as the size and type of your boat’s engine. A good rule of thumb is to choose a deep cycle battery with a capacity that is at least twice the amp-hour rating of your boat’s main electrical load. By considering these factors, you can select the best deep cycle battery for your boat or vehicle.

What are the procedures for charging a deep cycle battery?

Below are some of the procedures that you can follow for charging your deep cycle battery. Moreover, we have some charging deep cycle batteries with alternators too. So don’t forget to check them.

1.Choosing your charger:

No battery can get power without using a charger or other charging appliances. So this charger is the essential thing for better and smooth charging. We focus on bringing some easy information for choosing a charger. Good charger brings many conveniences for charging and loading methods. The main feature of a premium-class charger is that it brings fast charging to provide you a quick backup. The chargers are keeping two different styles of construction where the first one is regular and the second is modern. 

The regular charger is compatible with a flooded cell battery. This charger works to charge the battery at a high ampere rate. A great speed difference sustains between both of these batteries. Also, this charger can damage your AGM and GEL batteries. Therefore, make sure to get a modern charger that is applicable for all AGM and GEL batteries. In different battery cases, you have to choose the prescripted charger for your battery to maintain its durability. We are bringing complete information for these two different batteries for your desired choice.

2.Special deep cycle Battery charger:

Almost all of the modern battery chargers have a specific AGM and GEl battery foremost setting. AGM batteries need to get this modern charger setting. The charger for AGM batteries has the two most exciting and eye-catching features. This charger allows one to get a hundred percent charge with great maintenance and protects the battery from getting overcharged. On the other hand, this battery adds three best working steps for charge those are as follows:

  • Bulk charging for low ampere charging to protect the battery from overheating
  • Absorption charging option for reducing current supplies gradually until the complete charge
  • Float charging stage for maintaining the battery by monitoring, and it has got a trickle charge

3.Regular charging battery:

This regular battery is constructed specially for flooded batteries, and it charges them very fastly at a high ampere rate. On the other side, for AGM and GEL batteries, this charger can damage the inner system. Also, this battery can cause overheating aspects and can prevent the battery from getting charged. You can not leave it connected with the battery; doing this will cause serious damaging issues with your battery. So charge it completely in your protection to disconnect it before getting the work.  

4.Ampere function:

Get a charger that will deliver ten percent of the complete ampere range of the battery. For example, if you have a 50-ampere battery, the charger will have to provide 5 amperes for better charging options. 

5.Deep Cycle Battery Charging Time:

Charging depends on the type of chargers. Both chargers function at different timings, with charging together with different probabilities. In the case of a smart or modern charger, the battery gets its charging ways directly with an automatic system. This unique system automatically generates a maintained charge rate for the complete loading of power. It catches a maintenance mode after full charging to sustain durability for a long time. 

Conversely, if you have got a regular charger, use a manual system for easy and reliable charging. You have to divide the charger output battery rating for a conclusion. But this method works at a low rate of ampere. Surprisingly at 2 amperes, the battery of a hundred-ampere hour completely charges after two days.  Moreover, so charging a deep cycle battery with regular charger is possible too. 

6.Charger connecting process:

Let us clarify this connecting method in some steps to ease your hassles and efforts for further convenience. First of all, you have to check if battery terminals are neat and clean. If it is not clean, then remove all the dirt and grease. Easy cleaning can be done by using wire wool. Ensure that all cables are connected firmly with the battery terminals. On the top, create a connection of the red terminal with the red cable and then connect the negative black terminal. After that, connect your charger and switch it to the on mode. Check the indicator for further charging clarity. 

The smart charger automatically indicates the achievement of total power for the charging method. So you don’t have to worry about losing any battery power or getting any bruise effect. On the other side, keep your attention on the battery if you have connected a regular charger. It is because a regular charger doesn’t show the indication level for charging, keep looking at the charger for completion. 

Unplug the black terminal that is followed by the red terminal After the complete charging method. Then, give greasing to the terminals and joint points to prevent them from corrosion errors. 

7.Anderson connecting system:

Charging deep cycle battery in small storage is difficult, so we are discussing the best ways on that account. Anderson connectors can do this method. These connectors provide the easiest and hassle-free charging opportunity, even in the small battery box. Also, you can connect them in any dimension and even in any position. 

8.Alternator charging option:

Two of the best alternator ways are discussed below to provide genuine information on RVs and boat battery charging. 

  • An isolator is used for charging the batteries separately to provide the best backup. It charges the battery with lower voltage until batteries get equal power. After that, it will charge both of the batteries simultaneously. It’s one of the best alternators for charging deep cycle rv batteries for you. 
  • Promariiner digital mobile charger 130 inches provides reliability for alternator and battery. This system has added a smart charging application to provide correct charging amperes. Also, it works to promote equal and steady amperes every time. 

Final thoughts:

As discussed above, charging a deep cycle battery has been effortless in a minimized conversation. First, you have to find the best charger for your battery then work as reported in the upper prescription. Charge the battery according to the given information to get reliability and sustain your battery’s quality. 

Frequently Asked Questions

Do deep cycle batteries need special charger?

Yes, deep cycle batteries vary with the qualities and specifications, so they need different charges. On that account, we have discussed some of the best charges for deep cycle batteries above. You can fix the best charger according to the features of your batteries to have the best charging opportunity. 

Can you overcharge a deep cycle battery?

Overcharge is the most common problem with batteries. If we overcharge the battery, it gets down day by day with its quality and also doesn’t completely charge it. That is, overcharging a battery is not good for the quality and performance. But, some of the deep cycle batteries offer to overcharge them within the range of amperes of the charger. 

Is it better to charge a deep cycle battery slow or fast?

Whether the slow and steady method is recommended for charging a deep cycle battery, fast charging is recommended for some of the batteries. Also, this slow charging will sustain all the power reliably with more durability.
