Torches on AA batteries

AA

— one of the most common types of interchangeable elements today; such power supplies, colloquially known as "AA batteries", are widely used in various electronic devices and are sold everywhere. However, in modern flashlights this option is less common than the more miniature AAA — the development and reduction in the cost of LEDs made it possible to effectively use more miniature power supplies. However, models for AA elements are also quite popular.

Cells of this type can be produced both in the form of disposable batteries and in the form of rechargeable batteries. At the same time, both of them can differ markedly in capacity; accordingly, the battery life of a flashlight with such a power supply will be different — depending on the brand of batteries (accumulators) used. Also note that this type of power supply — like other types of replaceable cells — is inevitably associated with additional expenses: you will either have to regularly buy fresh batteries, or spend money on a set of batteries with a charger.
