Alkaline batteries

Alkaline batteries are a type of primary (non-controllable) electrochemical battery often used in consumer electronic devices. These batteries are named after the electrolyte they contain - alkaline hydroxide. The most common type of alkaline battery is the AA battery (or also known as the LR6 alkaline battery).

Alkaline batteries have several advantages over non-alkaline batteries:

Higher capacity: Alkaline batteries have a higher capacity compared to non-alkaline batteries, which means they can provide power for a longer period.

They suffer from self-discharge: Alkaline batteries have a lower self-discharge rate than non-alkaline batteries. This means they discharge more slowly when inactive, allowing for longer storage without losing power.

Higher voltage: Alkaline batteries provide a more stable voltage for most of their life cycle, which ensures more reliable operation of devices.

Better performance under high load: Alkaline batteries have the ability to maintain a stable voltage even under high load. This means that they are more suitable for devices that require high performance, such as digital cameras or toys.

On the other hand, non-alkaline batteries (such as zinc-carbon batteries) have a lower power capacity and a shorter lifespan compared to alkaline batteries. However, they are often cheaper and more suitable for devices with low power requirements, such as wristwatches, remote controls and simple electronic devices.
