Are you wondering what NiCad batteries are and where they are used? In this article, we will share with you a lot of information about them so that most of your questions about these batteries will be answered.
Most especially, we will share with you information about how to recondition NiCad batteries so that you don’t have to buy new ones, allowing you to save money in the long run. Let’s begin!
Most of the appliances that we use today utilize batteries for operation. When these batteries lose power, we tend to throw them away as the apparent action.
Here are some free tips where you can learn how to bring any dead battery back to life.
One important thing that most of us forget is that these cells can be restored. Read along as we will share with you very useful knowledge that can help you bring these old and dead batteries to life.
Understanding the NiCad Battery
Before we think about reviving a battery, the important thing is to understand what NiCad batteries are. These batteries are made of positive electrode which is created of Nickel Hydroxide and the negative electrode which is made of Cadmium Hydroxide.
These batteries have memory, and there is a recharging option for most of the NiCad batteries. These batteries create power for emergency lightings, photography equipment, flashlights and many other portable types of equipment.
The NiCad batteries have different charge times, an overnight recharge of a single battery can lead to a power supply to the equipment for 14 to 18 hours. However, it depends on the conditions where the battery is used and the voltage.
If the temperature of the environment where the battery is used is high, then the life of the battery will reduce. Thus, high temperatures and the dry climate should be avoided as much as you can.
It may even lead to leakages. A good temperature range to use a rechargeable NiCad battery should be 20 degrees to 45 degrees. It should also be used for optimum charging as overcharging may lead to damage. This can even damage a good quality battery.
Why Do NiCad Batteries Die?
NiCad batteries are a name derived from the composition if Nickel and Cadmium battery. They are rechargeable batteries that are made of elements Nickle(Ni) and Cadmium(Cd) in various structures.
There is an electrolyte composition of these batteries and they are potassium Hydroxide(KOH) with the positive electrode as Nickel Hydroxide(Ni(OH)2) and the negative electrode as Cadmium Hydroxide (Cd(OH)2).
The power that these NiCad batteries work with is a different steady voltage of 1.2v each cell. When this energy is depleted completely, the battery dies.
The benefits of the NiCad batteries are that they have a powerful voltage output until the last moment of the battery power. Some NiCad batteries have an extra power cell. It can provide power until the end of use.
There is also low internal resistance because the battery can deliver high power to the equipment even until the end of the use. This internal resistance sometimes leads to quick discharge of the battery, and overuse leads to the battery dying real fast.
There are simple steps of repairing these batteries. This will allow some extra uses of the same battery, and you won’t be needing to buy new ones soon.
Even though these batteries are small, they have a long life, and when they are used and restored, their life is increased.
These batteries provide added power to the devices that work without continuous power charging, and the memory contains long life before the device dies.
When Should NiCad Batteries Be Repaired?
Life, as it seems, comes to a standstill when the appliances stop working. This happens when the power-giving battery dies and is not reconditioned. The NiCad batteries are rechargeable batteries which are made of Nickel and Cadmium.
These batteries are highly popular as they are powerful and work best for all cordless devices.
They are also economically viable and safe to use. These batteries are available in many sizes and are the reason why many of your appliances provide the services they do. The secured storage of these batteries is also a reason why they are used in many devices.
The NiCad batteries can maintain a constant voltage of 1.2v per cell, which is maintained until the end of its life unless the battery is discharged. There is low internal resistance in these batteries, and this leads to quick discharge.
The NiCad batteries over the time lose its ability to recharge quickly and shocking as it may sound, up to a 100% even when the battery is half charged.
To overcome this memory effect, the battery should be repaired timely. The process of complete discharge causes the battery to lose this effect and starts to function with its full power. This full release to be able to repair the battery can be done every 2-3 months.
The memory effects are considered the main reason why the NiCad should be repaired from time to time. After repairs there are higher levels of performance and the problem of self-discharge is also solved with the repairing.
Reviving Dead NiCad Batteries by Freezing
The Nickel and Cadmium batteries are the most popular form of rechargeable batteries that are used in various batteries. These powerful batteries are an excellent source of power for cordless devices.
The torches, emergency lightings, photography equipment, laptops and many other such devices use this battery option. These batteries are made of efficient technology that provides high power until the end of discharge.
The batteries can be recharged for reuse, and that is how the equipment makes continuous use of these batteries. The problem arises when these batteries are used over a period.
The efficiency decreases along with the decline in performance of these batteries. Battery recharge by freezing is done to gain its lost power. It is a great method which is simple to use and highly efficient.
Here are the steps to follow for repairing the batteries:
- Take the battery out of the electronic device.
- Put this battery in a plastic bag and seal it properly. Make sure that the battery is dry and clean before placing it in a bag.
- Place this battery in the freezer for an hour or more.
- Remove the battery from the freezer.
- Clean it off is there are any water content or frost particles on the battery.
Tap the battery now with the screwdriver. The freezing of the battery pack makes the crystals highly fragile. Tapping the battery reaches and the glass breaks out.
This is the main reason that restores the primary function of the battery which allows longer power time.
