Batteries contain chemical substances isolated from each other. When the battery is connected to a circuit, the substances react chemically, causing electrons to flow from the cathode "-" to the anode "+". This is electric current. This process occurs on the three main elements of the battery device: anode, cathode and electrolyte. The difference in the materials of these elements determines the chemical system of the batteries: saline, alkaline (alkaline), lithium.

A battery drains when all electrons have moved from one group of atoms to another.

No. Battery sizes contain different amounts of chemical substances, the reaction of which releases a certain amount of electrical energy. The difference in the chemical composition of the battery also determines its service life.

Saline batteries are the oldest type of power cells. They are cheap but cannot handle strong and even medium loads, have low capacity and short shelf life. Alkaline batteries have higher capacity, work in powerful consumers and have a long shelf life. Lithium batteries have the best capacity and current consistency under high load. But lithium batteries are significantly more expensive than alkaline ones, and their use is justified in small disc sizes.

Alkaline batteries can vary significantly in quality. The TDS technology used in IEK batteries ensures maximum filling of the capacity.

Inside a battery with TDS, special materials are used in the active mass that have high energy density. This allows the battery to be filled with energy to the maximum. TDS technology pays special attention to the processes of ion movement inside the battery. It optimizes the electrode structure to increase the speed and efficiency of movement of positive and negative ions between electrodes. This contributes to improved performance and increased energy density. The battery design also plays an important role in TDS technology. Optimizing the shape, size and location of components improves the battery's efficiency and allows its capacity to be used to the maximum.

No, this will reduce battery performance and may cause damage.

Batteries should be stored so that their contacts do not touch each other or other metal small items, such as coins. Otherwise, they will quickly discharge and the contacts will oxidize. It is better to store batteries in packaging or a plastic container, never metal, without direct sunlight.

Usually saline batteries leak. The leaked electrolyte, if touched, causes a chemical burn. The batteries should be removed immediately, always with household gloves. The leakage site should be wiped thoroughly. IEK alkaline and lithium batteries are sealed and do not leak.

This is a battery whose design allows current to be reversed from "+" to "-", i.e., to be charged. By choosing a rechargeable battery, you care about the environment. Their usage cycle is much longer, meaning you need to find disposal sites less often.

Accumulators are advisable to use in devices with high consumption (photo flashes, toys with an electric motor, etc.) and frequent use.

The service life of your accumulators directly depends on the charger. Poor-quality chargers can damage accumulators, reduce their capacity and render them unusable.

Regular batteries cannot be recharged — this can lead to fire and even explosion.

Despite the fact that IEK batteries and accumulators do not contain dangerous mercury, cadmium and lead, the chemical elements they contain should not enter the soil. Used batteries must be collected and handed over to specialized collection points in stores, management companies and recycling centers.
