Batteries for devices

Batteries as a power bank

Batteries are a miniature autonomous source of electrical energy, formed by a chemical reaction between the active elements in the sealed battery case. Batteries are an extremely convenient and widespread source of electricity in the home.

Types of Batteries

• alkaline (disposable);
• rechargeable (rechargeable);

Batteries can be of various types depending on their composition and mode of operation. In general, they are divided into rechargeable (rechargeable) and ordinary or standard (disposable). Rechargeable batteries have one main advantage over regular ones, and that is that they are suitable for repeated use after being recharged with a suitable charger.

Subtypes of Batteries

Depending on their structure and composition, batteries can be of several main subtypes:

• Nickel-cadmium batteries (NiCd) - These batteries are very durable and difficult to damage. The price of nickel-cadmium batteries is lower than the price of other batteries. Their energy density is 40 Wh/l. Their internal resistance is very low, respectively, the batteries maintain a low temperature, thanks to which they charge and discharge much faster.
• Nickel-metal hydride batteries - Their abbreviation is NMH or NiMH. They are among the most popular and frequently used batteries because they are convenient - they have a large capacity at the expense of a small and compact volume. Unlike nickel-cadmium batteries, nickel-metal hydride batteries have a higher level of self-discharge, but are sensitive to low temperatures and temperature fluctuations.
• Lithium-ion batteries (LiIon)  - Lithium-ion batteries are far more durable and compact than nickel-metal hydride, but on the other hand they are much more expensive. They are most often used in mobile communications, digital devices such as cameras, telephones or even watches. They optimally combine long life and reliability with low weight and volume.
