Batteries are devices users use for both their convenience and portability. They can perform many different functions. Batteries came into play due to the need to store generated electrical energy. A battery is a collection of one or more cells that go under chemical reactions to create the flow of electrons within a circuit. There is a lot of research and advancement going on in battery technology, and as a result, breakthrough technologies are being experienced and used around the world currently. Here we will discuss 9V RECHARGEABLE BATTERIES. But let us first see what is a battery, its types and in which sizes are batteries available.
Battery cells are usually made up of three main components.
- The Anode (Negative Electrode)
- The Cathode (Positive Electrode)
- The electrolytes
Types of Batteries
Batteries generally can be classified into different categories and types, ranging from chemical composition, size, form factor and use cases, but under all of these are two major battery types.
- Primary Batteries
- Secondary Batteries
1. Primary Batteries
Primary batteries are batteries that cannot be recharged once depleted. The Primary batteries are made of electrochemical cells whose electrochemical reaction cannot be reversed.
Types of Primary batteries
- Alkaline batteries.
- Aluminum air batteries.
- Atomic batteries.
- Dry cell.
- Mercury batteries,etc.
2. Secondary Batteries
Secondary batteries are batteries with electrochemical cells whose chemical reactions can be reversed by applying a certain voltage to the battery in the reversed direction. They are also referred to as rechargeable batteries. Secondary cells, unlike primary cells, can be recharged after the energy on the battery has been used up.
Types of Secondary batteries.
- Lithium-ion(Li-ion)
- Nickel Cadmium(Ni-Cd)
- Nickel-Metal Hydride(Ni-MH)
- Lead-Acid
| Primary Batteries (Non-Rechargeable) | Secondary Batteries(Rechargeable) |
| Alkaline | Lithium Ion(Li-Ion) |
| Aluminium Air | Nickel Cadmium(Ni-Cd) |
| Atomic | Nickel-Metal Hydride(Ni-Mh) |
| Dry | Lead Acid |
| Mercury | |
Different sizes of batteries
- 4.5 V battery.
- D cell.
- C cell.
- AA cell.
- AAA cell.
- AAAA cell.
- A23 battery.
- 9V battery.
Moving on further, as we have already discussed batteries and their types and sizes, let us focus on our main topic a 9v battery.
9v batteries
9V battery have two variants:
(1) Alkaline 9V batteries. (2) Rechargeable 9V batteries.
What is 9v RECHARGEABLE Battery?
The 9V battery was originally invented for radios in the 1950s. These provide long term running in all types of electric devices. Also, they are compatible to support all portable devices. Today, the 9 Volt battery is used in every small day-to-day device. Therefore, such a battery is beneficial for all types of electric devices that need superb voltage.
What are 9v Batteries Used for?
9V Batteries are used in devices such as Clocks, Smoke Detectors, Walkie Talkies, Radio, and many more.9 V Batteries are also used for one more important work and that is to back up the power.
Why Choose Rechargeable Over Alkaline?
Disposable alkaline batteries feel like a ripoff. They’re expensive, they have a low capacity, and they can leak while in storage. So why not power your new devices with a set of rechargeable 9v batteries?
What to look for in a Rechargeable Battery?
- Capacity-Alkaline batteries drain faster than rechargeable.
- Cycles– Rechargeable batteries slowly break down every time they’re used.
- Consistency-Cheaper rechargeable batteries tend to suffer from inconsistent capacities and lifespans.
- Self-Discharge-Rechargeable batteries slowly lose their charge while not in use.
Now that you know what you’re looking for in rechargeable batteries let’s get into it. Here are our favourite best rechargeable 9V batteries.
