Get out on your favorite river, lake, and other waterway and have yourself a blast

Boating is one of the spring and summer pastimes that offers you many options for having fun. The things you can do with a boat are endless. People Ski, Parasailing from the back of one, and of course fishing.​

The Deep Cycle Marine Battery is the unsung hero of summer vacation, fishing outing, and exploring the great outdoors on lake, river, and tributary. But, it needs care and feeding to make sure it will be in its best condition when you need it most.

So the first thing you need to know is how to charge a deep cycle battery properly.

​Start With The Right Charger

A Deep Cycle Marine Battery is not like the battery in your car.​ The basic chemistry of a car battery and a marine battery are the same. However, The Deep Cycle Marine Battery is an advancement over traditional marine batteries and the car batteries.

It is often called a hybrid as it has both the characteristics of a quick discharge and high amperage. But, it can also provide a long-term output as well.

​Deep Cycle Marine batteries can sustain up to 80% discharge and still be recharged again and again. But a car battery can only handle a 20% discharge.

How To Charge A Deep Cycle Battery​ Properly

​There are two methods. One is to charge the Deep Cycle Marine Battery in place and the second is to remove the battery from your boat and use a portable charger that you connect directly to the Deep Cycle Marine Battery.

​Best Way To Charge A Deep Cycle Marine Battery

The best way to charge a Deep Cycle Marine Battery is to get a charger designed for the task.

Just connect the clamps according to the directions, and it's auto-sensing circuitry monitors the environment and the Deep Cycle Marine Battery to provide a fast charge without damaging your battery.

​Here's how to use a portable deep cycle marine battery charger

1. Always before charging a battery in using the charger is best to refer to the manual that came with both the battery and the charger.

2. When using a portable charger disconnect your Deep Cycle Marine Battery from your boats electrical system.

3. Make sure you're working in an area with good airflow as when you're charging a battery gasses may be released.

4. Clean and inspect the battery terminals. Remember to wear protective I covering and gloves as the corrosion may contain sulfides which can irritate both eyes and skin.

5. The Deep Cycle Marine Batterires are sealed units usually and require no topping off.

6. With the charger turned off and wearing rubber gloves connect the red clamp of the battery charger to the positive battery terminal. You can identify this by the "+" marked nearby. The Newer chargers sense polarity and will let you know if you got it reversed.

7. Next, connect the black clamp to the terminal marked with the "-" symbol.

8. Plug your charger when appropriate wall receptacle. This will usually be the domestic current of 110 to 120 V AC.

9. On the Chargers front panel has today's battery chargers can handle a variety of battery types. You want to select the one that matches the type of the Deep Cycle Marine Battery that you have.

10. Press the start button and allow the battery to charge. The unit will automatically charge the battery and notify you by indicator light when it's finished.

11. Turn off the charger, unplug it, and disconnect the battery for replacement on the boat or storage.​

How to charge a deep cycle battery properly

Is it okay to use a trickle charger on a deep cycle marine battery?​

No, A car battery charger on trickle charge is too low to do the job. 10 amps are needed for Deep Cycle Marine Batteries. They have to be overcharged to 106%.

So, make sure you choose the correct charger for your battery. In this way, you charge your battery correctly and prevent damage and ensure a long life.

How To Charge A Deep Cycle Marine Battery On The Water​

First of all, find out the right charger for you that hooks into your boat's electrical system and runs off the motor while it is running.

You just wire it into your boat's electrical system according to the enclosed instructions, and you don't have to worry about overcharging or undercharging ever again. Also, this charger will charge your Deep Cycle Marine Battery 2X faster than rates that others chargers will.​

If you compare the Battery specs with this charger, you see that is compatible with most Deep Cycle Marine Batteries and has the needed sensing circuitry to do the job right.

Also, you have an off-grid way to charge it. This is the perfect charger for charging your Deep Cycle Marine Battery while you on the water and can't get it done the usual way.​

How To Charge A Deep Cycle Marine Battery Fast​

Sometimes, you may want to charge your Deep Cycle Marine Battery faster as you need the battery ready sooner than waiting the standard charge time. You can do this by either boosting the charge to 20 amps.

But, this will reduce the life of your battery. A better way is to use the Schumacher, which can give better charging times due to its smart circuitry that can regulate the current better. This is the best solution.

However, there is a third way, and that is, only take the charge to 90% instead of 100%, because the remaining 10% of charge takes the longest amount of time to complete. However, later, you should do a full charge normally.

How To Charge A Marine Battery​

Well, the process and recommendation is almost same.​ But there are few things you have to know about. Here is the detail instruction about how to charge a marine battery.

Post Summary

​Today you have learned how to charge a deep cycle battery properly. They have 80% discharge rate over the 50% rate of conventional marine battery.

Here is a video about how to charge a deep cycle battery properly.

You've seen the proper way to charge one using a portable charger and how you need to rely on the technology to do the job correctly. However, you can fudge the process by only charging to 90% of capacity to save time.

Finally, we even threw in a way to keep it charged without resorting to the Grid and raising your electrical bill. All in all, you have the perfect solution to keep your boat's battery in tiptop condition for water sports, relaxing, and fishing.
