Rely on alkaline batteries: Small, mobile and always ready!
Alkaline batteries are one of the most widely used power sources for portable electronics and are characterised by their high energy density, long shelf life and reliability. Developed as an improvement on traditional zinc-carbon batteries, they offer a more consistent voltage output and a longer life. This type of battery has played a significant role in electronics and people's everyday lives over the years. Below, we will dive deeper into the world of alkaline batteries to better understand their characteristics, applications and variations.
What are alkaline batteries?
Alkaline batteries, more commonly referred to as alkaline manganese batteries, are a type of primary (non-rechargeable) cell. Alkaline batteries are based on an electrochemical reaction between zinc (anode) and manganese dioxide (cathode) in an alkaline solution, usually potassium hydroxide. When discharged, the zinc releases electrons that flow through the external circuit and travel to the manganese dioxide, providing electrical energy. Over time, or if stored improperly, they can leak, releasing the corrosive potassium hydroxide.
What are the advantages of alkaline manganese batteries?
Longer life compared to zinc-carbon batteries:
This is due to the alkaline electrolyte solution working more efficiently.
Better performance at high currents:
Alkaline batteries can deliver higher currents, making them suitable for devices that require a lot of power for short periods of time.
Longer shelf life:
They have a relatively low self-discharge rate.
Wide operating temperature range:
They can be used in a wider temperature range than many other battery types.
Density and compactness:
Due to their high energy density, they are often smaller and lighter than other battery types of similar capacity.
Are alkaline manganese batteries rechargeable?
Once discharged, they cannot be recharged. However, there are alkaline batteries on the market that are specifically designed to be recharged a few times, but they are not as common as normal alkaline batteries or other rechargeable battery types.
Note:
If alkaline batteries are not used for long periods of time or are stored incorrectly, the batteries can leak and damage devices. It is important to use and store alkaline batteries according to the manufacturer's recommendations and to dispose of them properly when they are used up.
What alkaline batteries are there?
Alkaline batteries, are available in a variety of sizes to meet the diverse needs of electronic devices. These batteries are widely used in many everyday devices, from remote controls to torches. Below you will find an overview of the most common alkaline battery sizes.
AAA (Micro) battery:
- Cylindrical shape, smaller than the AA battery.
- Used in smaller electronic devices, e.g. remote controls, wall clocks and portable electronics.
- Offers a nominal voltage of 1.5 volts with a capacity lower than that of the AA battery.
AA (Mignon) battery:
- Cylindrical shape, larger than the AAA battery.
- Commonly used in a variety of devices, including remote controls, cameras and torches.
- Also offers a nominal voltage of 1.5 volts with a medium capacity.
C (Baby) battery:
- Cylindrical shape, larger than AA and AAA.
-Used in devices with higher power requirements, e.g. larger torches or portable radios.
- Supplies a nominal voltage of 1.5 volts and stores more energy than AA or AAA batteries due to its size.
D (mono) battery:
- Large cylindrical shape.
- Used in devices with very high power requirements, e.g. large torches, boomboxes or certain toys.
- Has a nominal voltage of 1.5 volts and offers a significantly higher capacity due to its size.
9-volt block battery (E-block):
- Rectangular shape with two contacts on the top.
- Frequently used in smoke detectors, some remote controls and devices that require higher voltages.
- Supplies a nominal voltage of 9 volts.
4.5 volt flat battery:
- Flat, rectangular shape.
- Traditionally used in torches and some toys.
- Consists of three 1.5 volt cells connected in series and delivers a total of 4.5 volts.
Each of these batteries has specific applications based on the power requirements of the particular device. It is always advisable to use the correct battery size and type to ensure optimum performance and safety.
