Why Do Rechargeable Batteries Eventually Need to be Reconditioned?

Rechargeable batteries are essential to modern life, powering everything from cell phones to laptops. However, even the best rechargeable battery will eventually need to be reconditioned. Reconditioning batteries helps to restore their capacity and prolong their lifespan.

There are several reasons why rechargeable batteries need to be reconditioned:

  1. The battery plate becomes coated with a layer of oxide. This oxide layer reduces the battery’s ability to accept a charge. Reconditioning a battery removes this oxide layer, allowing the battery to accept a charge more effectively.
  2. The electrolyte solution inside the battery breaks down over time. This breakdown reduces the battery’s ability to store charge. Reconditioning replenishes the electrolyte solution and restores old batteries.
  3. As batteries age, they become less efficient at converting stored energy into usable power. Reconditioning can help increase the efficiency of an aging battery, allowing it to power devices for more extended periods.

The Different Kinds of Rechargeable Batteries

There are three basic types of rechargeable batteries: Nickel-cadmium (Ni-Cd), Nickel metal hydride( NiMH), and Lithium-ion. Though they all look similar on the outside, there is a vast difference between them when you start to explore their properties more closely.

Ni-Cd Batteries

Ni-Cd batteries are a type of rechargeable battery that can be used for a variety of applications. They were first developed in 1899 and have been used extensively in various applications since the 1950s. Ni-Cd batteries are made with Nickel and Cadmium electrodes, which give the batteries their distinctive silver and blue color. Ni-Cd batteries are known for their high discharge rate, meaning that they can provide a large amount of power in a short time. However, the nicad battery reconditioning process is complex. When a battery is over-discharged, the Cadmium in the electrode can become chemically active and cause the formation of damaging dendrites. As a result, it is essential to be careful when using and to store Ni-Cd batteries to avoid damaging them.

Nickel metal hydride( NiMH) Batteries

Nickel metal hydride batteries are a type of acid battery. They are made with a nickel-based positive electrode and a metal hydride negative electrode. Sodium sulfate is used as the electrolyte. NiMH batteries are also known as “hybrid” batteries because they contain both acid and metal. The advantage of NiMH batteries over other acid batteries is that they can be recharged many times without losing capacity. NiMH batteries can also be reconditioned if their capacity starts to diminish. To do this, the battery is discharged and then recharged several times. The battery restoration process increases its ability to hold a charge and extends its life. NiMH batteries are more expensive than other acid batteries, but their longer life and higher capacity make them worth the extra cost.

Li-Ion (Lithium Ion) batteries

There are many different types of batteries, but one of the most popular is the lithium-ion (Li-Ion) battery. This type of battery is used in a wide variety of applications, from cell phones to laptop computers. Li-Ion batteries have many advantages over other types of batteries. They are lightweight and have a high energy density, meaning that they can store more energy than other types of batteries. Li-Ion batteries also have a longer life span than other types of batteries, and they can be recharged more times before they need to be replaced. In addition, Li-Ion batteries are not susceptible to the “memory effect,” which can reduce the capacity of other types of batteries over time. As a result, Li-Ion batteries are an excellent choice for many applications.

How to Prolong the Life of Your Rechargeable Batteries

Rechargeable batteries are a great way to save money and reduce waste, but they can be finicky. To get the most out of your rechargeable batteries, it’s important to properly care for them.

Here are some tips for prolonging the life of your Ni-Cd batteries:

-Avoid deep discharge. Deep discharge occurs when a battery is completely drained. This can damage the battery and shorten its lifespan. Try to avoid letting your Ni-Cd batteries go below 20% charge.

-Don’t overcharge. It’s important not to overcharge Ni-Cd batteries, as this can also damage the cells and shorten their lifespan. Most Ni-Cd chargers will have an automatic shut-off feature to prevent overcharging, but keeping an eye on things is still good.

-Store in a cool, dry place. Heat and humidity can accelerate the self-discharge rate of Ni-Cd batteries, so storing them in a cool, dry place when not in use is best.

Nickel metal hydride( NiMH) Batteries

Nickel metal hydride batteries are a type of rechargeable battery commonly used in digital cameras, camcorders, and portable electronics. NiMH batteries offer advantages over their traditional counterparts, including a longer lifespan and higher energy density.

-Avoid extreme temperatures: Both high and low temperatures can shorten the lifespan of your batteries. Try to keep them stored in a cool, dry place.

– Avoid leaving them discharged for long periods: When not in use, be sure to recharge your batteries regularly. This will help to prevent them from developing a “memory” that will shorten their lifespan.

Li-Ion (Lithium Ion) batteries

Lithium-ion batteries are one of the most popular choices for rechargeable batteries thanks to their high energy density and low self-discharge rate. To prolong the life of your lithium-ion batteries, follow these simple tips:

-Avoid fully charging or discharging your battery. Instead, keep the battery between 40% and 80% charged.

-Store your battery in a cool, dry place. Heat and humidity can shorten the lifespan of any battery.

-Use quality chargers and cables. Poor-quality chargers can overcharge your battery and damage the cell.

-Regularly calibrate your battery. This helps to ensure that the battery is properly balanced and prevents it from being overcharged or discharged.

How Do You Recondition a Battery

Battery reconditioning is the process of restoring a battery to its original capacity. This can be done by charging and discharging the battery several times. This improves the battery life and performance. Battery reconditioning can also be done by replacing the battery cells. The most crucial factor is ensuring the battery is not overcharged or discharged. This can damage the battery and make it unusable.

Two ways to do this are through battery desulfation and battery equalization. 

  • Battery desulfation is the process of removing sulfate deposits from the battery plates. These deposits can build up over time and cause the battery to lose capacity.
  • Battery equalization balances the battery cells so that they all have the same voltage. This helps to extend the battery’s life by preventing cell failure. 

Both battery desulfation and equalization can be done in a more controlled way by using a battery reconditioner. A battery reconditioner is a device that safely applies a controlled voltage to the battery cells, allowing for both desulfation and equalization without damaging the battery. 

This restores your battery to its original condition, extending its life and saving you money in the long run.

Steps to Rejuvenate a Rechargeable Battery

If a battery doesn’t work after reconditioning, or if it’s not a good candidate for reconditioning according to its tests, it might be possible to make the battery usable again by “rejuvenating” it.

You’ll need to use a voltage slightly higher than the battery’s standard voltage to charge a battery. Here’s an overview of the steps involved:

  1. To rejuvenate a bad battery or cell, you must first identify a “rejuvenating battery” to apply voltage. This could be anything from a 9-volt battery for small packs to a 12-volt battery for higher-voltage power packs. If more than 12 volts are needed, connect two 12-volt batteries so that the + terminal of one is connected to the – terminal of the other; this will give you 24 volts from the remaining two terminals.
  2. Clip the alligator test lead onto the positive and negative terminals. Make sure that you have the black clip connecting to the negative terminal and the red attaching to positive.
  3. To rejuvenate the battery, touch the black alligator clip to the negative terminal of the battery and very briefly touch the red clip to the positive terminal of the battery. Rejuvenation should not exceed 1-3 seconds.
  4. Check the voltage of the battery after you’ve tried rejuvenating it. If it’s not close to the nominal voltage, try again and tap the positive terminal a few times with the red clip. Unfortunately, the battery cannot be saved if that doesn’t work.
  5. If the battery is successfully rejuvenated, recharge it to a total state of charge. If necessary, recondition the battery too. 

The rejuvenation process described above can be completed on a single-cell battery if you can take the battery pack apart and identify which cells are damaged or shorted.

Lead Acid Battery Reconditioning Guide

A lead acid battery is a type of rechargeable battery that uses a chemical reaction to create a flow of electrons. The lead acid battery was invented by French physicist Gaston Planté in 1859, making it the first rechargeable battery. Lead acid batteries are used in various applications, including automotive starter batteries, backup power supplies, and golf cart batteries. They typically have a higher energy density than other types of batteries, making them ideal for applications that require a large amount of power. However, lead acid batteries also have some disadvantages, including a shorter lifespan and more significant environmental impact. Despite these drawbacks, lead acid batteries remain popular for many applications due to their high energy density and low cost.

Reconditioning Lead Acid Batteries 

Here are a few methods to recondition lead acid batteries.

  • Apply an “equalizing charge

Lead acid batteries are one of the most common batteries used in vehicles today. Over time, lead acid batteries can lose their ability to hold a charge, making them less effective and reliable. One way to help extend the life of a lead acid battery is to recondition it regularly. An equalizing charge is a reconditioning that helps to restore the battery’s original capacity. To equalize a lead acid battery, you’ll need to slowly charge it until it reaches its full capacity. This process can help prevent lead sulfate buildup and improve the battery’s overall performance. As a result, equalizing charges is an essential part of lead acid battery maintenance.

  • Using chemical addition

Lead-acid batteries have a limited lifespan and will eventually need to be replaced. You can DIY battery reconditioning with a few simple tools. First, you will need to remove the battery from the application it is being used in. Next, clean the terminals and connectors with a brush and distilled water. Once the terminals are clean, add the battery-reconditioning chemicals. Finally, recharge the battery and reinstall it in the application.

  • Using special desulfating equipment

Over time, lead acid batteries will sulfate. This happens when the lead in the battery oxidizes and forms lead sulfate crystals on the lead plates. As these crystals build up, they prevent the flow of electrons and reduce the battery’s ability to hold a charge. However, there is hope for sulfated batteries. With the help of special desulfating equipment, it is possible to break down the lead sulfate crystals and restore full capacity to the battery.

Types of Lead Acid Batteries 

Any device that uses electricity will likely have a battery of some kind, and there are many different types of batteries to choose from. Lead acid batteries are among the most popular due to their relatively low cost and high power density. Lead acid batteries come in two main varieties: flooded and sealed. Flooded batteries require regular maintenance, such as adding water to the cells, but they are typically less expensive than sealed batteries. Sealed batteries are maintenance-free but may not last as long as flooded batteries. Either way, lead acid batteries are a reliable option for many devices.

How to Maintain Your Lead Acid Batteries

Trick to bringing any battery back to life

If you want your lead acid batteries to last, here are a few things you can do:

  • Keep the battery terminals clean and corrosion free

Corrosion can build up on the terminals over time, eventually leading to electrical problems. If you notice any corrosion, use a brush to remove it. You can also use a solution of water and baking soda to neutralize the acids and help prevent further corrosion. In addition, be sure to keep the batteries clean and dry. Dirt and debris can cause electrical problems, so regularly wipe them down with a cloth or brush.

  • Maintain Correct Electrolyte Level

The electrolyte level in a lead acid battery should be checked regularly to ensure it is at the correct level. The level should be about halfway up the plates, and if it is too low, you can add distilled water to bring it up. Be sure not to overfill the battery, as this can lead to problems.

  • Prevent High Temperatures

High temperatures can shorten the lifespan of your lead acid batteries’ lifespan, so keeping them in a cool, dry place is essential. Avoid storing them in direct sunlight or near other heat sources. In addition, be sure to keep the batteries ventilated to allow excess heat to escape.
