Battery types, selection criteria and the most important parameters

Publish date 2021-02-28
Batteries are available on the market in various sizes and designs. In this article, we will focus on two types - alkaline batteries and rechargeable batteries.

Alkaline batteries

Alkaline batteries, i.e. the most common ones, are a non-rechargeable primary cell, i.e. they are disposable. The principle of operation of this type of battery is based on a chemical reaction taking place in it, which takes place with the participation of zinc and manganese oxide. The nominal voltage per one cell of these batteries is 1.5 V. The operating temperature range is between -30 ° C and + 70 ° C. The storage time of alkaline batteries is approximately 5 - 7 years.


Accumulator batteries, i.e. accumulators or rechargeable batteries, are primary cells that can be charged many times with direct current. It is enough to plug the charger into the socket, put the batteries in it and after a few hours, the battery is fully charged and ready for further operation. Batteries store and then release electricity thanks to reversible chemical reactions. The average voltage rating of these batteries is 1.2V (when fully charged it exceeds 1.4V). The operating temperature range is between -40 ° C and + 65 ° C. The storage time of the batteries is approximately 10 years.

Battery types and their application

We offer many types of alkaline batteries and accumulators. Below, we will present some of them, along with the markings in two systems - the more common ones, i.e. ANSI, and the markings according to the standards adopted by the IEC (International Electrotechnical Commission). Type D (LR20 according to IEC) - most often, in domestic conditions, used to power children's toys; in industry used, inter alia, for electric locks and other specialized devices; Type C (LR14 according to IEC) - most often used at home to power children's toys and flashlights; they are also used in industry - some manufacturers of specialized devices decide to power them with LR14 batteries; Type AA (LR6 according to IEC) - one of the most common, often called "sticks"; used in all kinds of electronic devices - from disposable cameras, through wall clocks to game controllers (pads); Type AAA (LR03 according to IEC) - right next to AA batteries, equally common, popularly called a thin finger; used, for example, in remote controls, digital cameras, computer mice and keyboards;

What to choose? Rechargeable battery or alkaline battery?

We have one answer to this question: it depends on the hardware in which it is going to be used. If we need a battery for a device where we rarely replace the batteries because they need a small amount of energy (for example, remote controls, flashlights, calculators), it is better to choose a battery from an economic point of view. However, if we need to power a device in which the battery will be replaced every 1-2 months, it is worth considering the purchase of batteries. If we have many devices at home, in which we often have to replace the batteries (e.g. xbox pad), then the best choice will be to buy batteries. An additional advantage in the case of rechargeable batteries is its contribution to the care for the environment. We invite you to familiarize yourself with our offer, and in case of any doubts, we remain at your disposal.
