How to Bring a Deep Cycle Battery Back to Life: Desulfating and Checking

How to Bring a Deep Cycle Battery Back to Life: Desulfating and Checking

Page view

There is a phenomenon in deep  cycle batteries many fear: Desulfation. Just what is it, and why do people fear them? Check this article out!

How to Bring a Dead Deep Cycle Battery Back to Life

To understand more about deep cycle batteries, we need to be able to distinguish them from other types of battery. Here is the basic definition of deep cycle batteries that can help you understand better.

Deep cycle batteries may appear to be conventional to some, but it’s due to the fact that they really have greater power than their usual counterparts. Golf carts and marine vehicles can profit from them, despite the fact that the amount of power isn't too overpowering. They're also great for revving up the engine. A deep cycle battery is the ideal option for you if you live in a cold area and need to expend extra effort to start your car.

What makes deep cycle batteries different from other batteries? To survive multiple charge and discharge cycles, deep cycle batteries include larger battery plates and a denser active material. Rather than delivering strong bursts of power for short periods of time, they are meant to provide continuous power with reduced current demand over longer periods of time. Repeated cycling does not produce the same degree of harm to a car battery as it would if it were used in the same way.

If your deep battery is dead, there is a method to revive it. Here’s how:

1. Make a list of the common home items you'll need to recharge your battery. Epsom salt, baking soda, and distilled water are the goods in question.

2. Take an initial charge reading on your battery. Although a poor result is to be expected, utilize a load tester to get a better idea of the battery's form. The amperes that your battery generates are measured with a load tester. As a general rule, the battery should provide high amperes in order to power the starting motor and start the RV's engine.

The power of a battery is commonly referred to as "cold cranking amps," or simply "CCA." When checked using a load tester, a good battery should bring the dial to the green ‘OK' region. If the dial settles in the red region at the conclusion of the load test, you'll know how weak your battery is.

3. Make careful to clean the battery's whole surface, including the terminal. Using a tissue or a cloth, wipe away any dirt, oil, or debris from the top of the battery. Corrosion is a natural part of the aging process for batteries. The white powder on the exterior of a corroding battery is easy to see.

Work gloves and even safety goggles can be used to clean your battery as an extra precaution. You may also clean the batteries with a cleaning solution composed of water and baking powder.

4. Remove the battery caps by loosening them. Simply screw off the caps to complete this procedure. Uncaping some battery models may necessitate the use of a flat head screwdriver. Remove all of the acid from the battery. Make sure you do this carefully since the acid can cause a scorching and unpleasant sensation if it gets into your skin. Prepare a bin or container in which to pour the liquid. Keep in mind where you'll be disposing of the battery's acid.

5. Make a solution using 10 ounces baking soda and 1 gallon purified water. It's not a good idea to combine all of the baking soda at once. Instead, do it in tiny batches to make sure the baking soda is well dissolved. Baking soda is one of the most effective cleaning agents available. It is connected with virtually all cleaning procedures, and the concept is the same here. Baking soda will aid in the cleaning of your battery's inside.

6. Fill each of the battery's cells with distilled water and baking soda solution. Using a funnel, go gently with this approach. Replace the battery caps. For around 30 seconds, shake the battery. Reinstall the battery caps. Fill the same bin with the distilled water and baking soda solution that you used previously.

Prepare another gallon of distilled water and 15 ounces of Epsom salt. To dissolve the Epsom salt more easily, use hot distilled water for this stage. You may use the same approach as you did with the baking soda and dissolve in smaller quantities. Pour the Epsom salt solution into each cell of the battery in the same way you did the distilled water and baking soda solution.

7. Slowly charge your battery for 24 hours with your battery charger. The battery lids do not need to be replaced because there is a risk of some liquid spillage during the charging phase owing to the hot solution. Check your battery's current volt measurement after 24 hours. The battery's power is expected to improve.

How to Desulfate a Deep Cycle Battery

Now that we’ve covered the basic definition of deep cycle batteries, let’s talk about desulfation. What is it, and what makes battery owners fear them? It is a condition in which lead sulfate crystals form on the lead plates. The symptoms are:

a) Low current supply

b) Plates with a white coating

c) High internal resistance

The overall frequency of each lead acid battery is between 2 and 6 megahertz. If low-power, high-frequency, high-voltage electricity pulses are put into the battery, the crystal deposits break and the sulfate returns to the electrolyte solution due to rhythmic resonance of the plates. However, this technique of desulfation typically takes three to four weeks, during which time the battery must be trickle charged, that is, charged in parallel with the desulphator, in order for the battery to be rejuvenated and fully charged.

Other desulfation systems include STAMP, microcontrollers, and the 555 timer, in addition to the above-mentioned.

How to Tell If a Deep Cycle Battery Back to Life

When charging a battery, if the voltage does not rise over 10.5 volts, the battery has a dead cell. The battery is sulfated if it is completely charged (according to the battery charger) yet the voltage is 12.5 or below.

Maintaining a deep cycle battery’s life, reviving it, and desulfating it isn’t hard, but the process requires extra details we need to pay attention to. Are you ready to do so?
