Batteries can be very expensive to replace. Be it laptop batteries, car batteries or even non-replaceable batteries that are inside modern phones nowadays, they are incredibly expensive to replace. Have you thought about battery reconditioning?
In some cases, old devices won’t even have replacement batteries available because they’re no longer in stock.
Reconditioning batteries allows you to preserve the function of your batteries and even refresh them , thus saving you a lot of money.
It’s also better for the environment because batteries themselves are very hard to recycle and they usually end up in trash bins and causing a huge impact to the well-being of the planet.
You’ll save money, you’ll save time. There are virtually no disadvantages of reconditioning your own batteries .
In case you are worried about your safety, be at ease. If the technique is properly learnt, it is quite safe.
You can practically get your old/dead batteries for free! You see, safe disposal is top priority, and many seemingly dead batteries are getting prepared for a new life again.
Batteries costs can add up fast, and you are saving a hefty sum if you simply recondition it instead of buying another one.
If you want to go green and save environment while working on renewable energy resources, this is a good opportunity. Not only you learn a skill that will be highly coveted in future, but you can also earn some extra cash for other pursuits.
Types of Rechargeable Batteries
There are many types of rechargeable batteries, each with different uses and applications.
The various types of rechargeable batteries and their uses are as follows:
Nickel Cadmium (NiCd) Battery
This type of battery is used when price, a high discharge rate and battery life are important.
The Nickel Cadmium battery is NOT environmentally friendly due to toxic metals contained in it, and main uses are for professional power tools, professional video cameras, biomedical equipment, and two-way radios. The chemical components of the NiCd battery, nickel oxide hydroxide and metallic cadmium, are the main disadvantage of this type of battery.
This type of battery has quite a low energy density and uses nickel oxide hydroxide and metallic cadmium as electrodes. NiCd batteries are also susceptible to a “memory effect.”
The NiCd (chemicals symbols of nickel and cadmium) battery has a terminal voltage of around 1.2 volts during discharge. They are made in various sizes and capacities and have a distinct advantage over other rechargeable batteries in their ability to deliver at high discharge rates.
Nickel Cadmium batteries use an alkaline chemistry and have an energy density approximately twice that of lead acid batteries.
Although once the preferred battery choice for applications regarding low power portable products, they have since been overtaken by the newer Nickel-Metal Hydride (NiMH) and Lithium batteries.
The most popular applications for Nickel Cadmium batteries include:
- Two-way radios
- Power tools
- Emergency lighting
- Medical instruments
- Electric razors
- Portable products (commercial and industrial)
- Nickel-Metal Hydride (NiMH) Battery
Nickel-metal-hydride batteries are closely connected to the above-mentioned Nickel Cadmium batteries, with the hydrogen being used as the active element rather than cadmium.
In comparison to the Nickel Cadmium battery, the Nickel-Metal Hydride battery has a higher energy density.
Unlike the NiCd, this battery does NOT contain toxic metals, and is usually used in mobile phones and laptops.
This type of battery are now a common consumer and industrial type battery. It has practically taken over the NiCd battery in applications.
The cell voltage for these types of batteries is 1.2 volts, with the electrolyte being alkaline potassium hydroxide. The energy density of NiMH batteries is around double that of lead acid batteries, and around 40% higher than NiCd batteries.
