Rechargeable battery pack - types and application introduction
What is a rechargeable battery pack?
Basically, it is a battery that can be easily recharged and used multiple times.
Unlike disposable batteries (that are only designed for single use), a rechargeable battery pack is specifically built to be used for a number of time. This ability makes it a more sustainable option as compared to other batteries available on the market.
Now, let us explain its working in detail.
How does a rechargeable battery pack work?
As we have already mentioned above, a rechargeable battery pack utilize a special chemical reaction for both storing and releasing energy.
When the battery pack is being charged, an electric current is applied to it that causes a chemical reaction and ends up stored in the form of energy. The energy is then stored in the battery’s special cells. The cells are made up of different materials like lithium, cadmium, nickel, etc.
When the battery is asked to power a device or electrical appliance, it then releases all of its energy gradually into the required device.
Remember, the chemical reaction that takes place in the rechargeable battery is reversible – which means when the battery is discharged, the stored energy is released as an electric current in the attached device or appliance.
The rechargeable battery pack comes with a battery charger that applies electric current to the battery. The charging process usually takes a maximum of one hour. However, the time may vary depending on the type and capacity of the rechargeable battery.
Different types of rechargeable battery packs
1.Nickel Cadmium Battery:
This battery is one of the earliest types of rechargeable batteries and is highly known for its ability to handle high current loads and high discharge rates.
Apart from these two benefits, these batteries also have a downside. These are prone to memory effect that affects their overall capacity with time. Wondering what the memory effect is? Let us explain.
The memory effect is when the nickel-cadmium battery is not fully discharged before re-charging it. This causes the battery to remember shortened runtime, which further results in reduced capacity.
2.NiMH (Nickel Metal Hydride Batteries):
NiMH is yet another type of rechargeable battery pack that is composed of hydrogen-absorbing alloy and nickel oxide hydroxide. These batteries offer more density as compared to Nickel-cadmium batteries and also have a lower memory effect.
For these reasons, these batteries are being used in many applications of human life, such as:
● Portal electronic appliances
● Powerful tools
● Hybrid vehicles
3.Lithium-ion batteries:
Lithium-ion batteries are one of the best rechargeable batteries, although there are several reasons behind their popularity. For example, these batteries offer maximum high density, low discharge rate, prolonged life span, and many more.
Additionally, these are composed of lithium cobalt oxide and a graphite anode and are commonly used in the following things:
● Mobile phones or tablets
● Laptops
● Electric vehicles and devices
4. Lead-acid batteries:
This type of rechargeable battery pack is composed of sulfuric acid electrolyte, lead dioxide, and lead. These batteries offer low-cost pet watts and can easily handle high current loads. However, these have a lower energy density as compared to other types that are discussed above.
These batteries are widely used in:
● Emergency lighting
● Backup power system
5.Sodium-ion batteries:
Sodium-ion batteries is the last type of rechargeable battery pack on our list. These make use of sodium instead of lithium. This is why these are considered modern batteries. These offer high energy density and low cost per watt. However, these are still in development, that is why they are not widely available and used.
What are the best rechargeable battery packs available?
Lithium-ion batteries are one of the best rechargeable battery packs available in the market and online platforms.
There are multiple reasons why these are considered the best option:
● Higher energy density: Lithium-ion batteries have the ability to store maximum energy in smaller sizes.
● Low self-discharge: This ability indicates that these can hold their stored charge for a prolonged period of time.
● Maximum lifespan: Lithium–ion batteries offer a longer lifespan, which means these can be charged and discharged several times.

How long does a rechargeable battery pack last?
There is no definite answer to this question because the lifespan of a rechargeable battery pack depends on several factors that are listed below:
1.Type of battery you have
2. How you are using it (carefully or carelessly)
3. Environmental conditions
4. Usage patterns
Usually, lithium rechargeable battery pack is long-lasting, with a lifespan of 3-5 years.
Are rechargeable battery packs better than disposable batteries?
Yes! Rechargeable battery packs are better than disposal batteries; there are multiple reasons behind “yes”. Those reasons are as follows:
1.Powerful and durable:
Reusable batteries are generally more powerful and durable as compared to disposable batteries. This makes them a more suitable option for charging electronic devices, especially those that require more power.
2.Environment friendly:
We all know that disposable batteries contribute to increasing environmental pollution. Disposable batteries equipped with toxic chemicals that can get their way into soil and then into water resources.
However, that’s not the case with a rechargeable battery pack; it produces less waste and contributes to reducing environmental pollution.
3. Cost-effective :
Rechargeable batteries are cost-effective than disposable batteries, this is so because they can be reused multiple times, while disposable batteries are only suitable for single-use. This means after one use, you will have to replace them.
