Batteries

A battery is a device in which chemical processes are converted into energy. That is, chemical energy turns into electricity, charging various devices. When the battery is discharged, it is charged. In this case, electrical energy is converted into chemical energy. That is, during the process of charge-discharge, a transformation of one type into another occurs.

Powerful and durable: the role of batteries in modern energy systems

Today, batteries have found application both for domestic use and in a professional environment. It is worth buying a battery in Kyiv and other cities for charging:

• road and rail transport;
• air transport, boats and yachts;
• electric scooters and electric scooters ;
• mobile gadgets, computer equipment, tablets;
• video surveillance systems;
• medical equipment;
• household and professional appliances.

The battery contains chemicals that enable energy conversion processes to occur. You can buy these types of batteries in the Etsenergy store.

1. Nickel-cadmium. A common option. Resistant to low temperatures, can be stored in a discharged state. Service life – up to 25 years.
2. Lithium: lithium ion or lithium iron phosphate. Characterized by minimal self-discharge and requires minimal time to charge. It has high energy density.
3. Lead acid. Resistant to current surges, easy to maintain. Refers to budget options.
4. Gel (a subtype of lead-acid). Complete sealing. The gelled electrolyte cannot leak. Resistant to temperature changes.

All types of batteries are used for home and professional use. A modern battery can be connected to alternative sources of electricity, such as solar panels or wind generators. This way you accumulate environmentally friendly electricity.

Energy without interruption: the importance of reliable batteries for electronics and transport

If you want to provide electronics, transport, household and professional appliances with an uninterrupted supply of electricity, you should buy a battery. When purchasing a device, consider the capacity. The larger the capacitance, the more electricity the device accumulates and the higher the voltage.

Dimensions and weight are of great importance. For frequent transportation, units with less weight are convenient. Before purchasing, find out in advance what maximum dimensions are suitable for you (for example, for a car). Also consider the location of the terminals. Their location varies in different models.

Temperature also affects battery performance. Some models do not tolerate temperature changes well and are unsuitable for use in the cold season. Hardy varieties can withstand temperatures ranging from -50 to +70°C.

Keep the unit clean. Regularly remove dirt from the terminals. As for disposal, some models (for example, those containing sulfuric acid) are disposed of in special containers for safety reasons.

In the Etsenergy store you can buy a battery in Kiev and any city in Ukraine at competitive prices. Products from manufacturers CSPower , EverExceed , PYLONTECH, LogicPower , Merlion and other companies meet quality standards, are distinguished by reliable assembly and high performance. You can buy goods over the phone or on the website in one click. All products are delivered anywhere in Ukraine by Nova Poshta. Consultants will guide you through the catalog and recommend exactly the product you need.

Battery types: chemical composition and applications

A battery is a device for storing electrical current. By connecting various consumers to the unit, you can fully power them with energy. During the chemical reaction, electricity is produced, which can be used for various purposes, be it charging a smartphone or using a battery as an emergency power source.

The design and chemical composition of batteries are constantly being improved to achieve maximum utility for consumers. So, depending on the active chemicals, batteries are divided into several types.

• Lithium (lithium-ion, lithium-iron phosphate, lithium-polymer are popular). They are worth buying for the high reload speed. This type has a high energy density. They are used almost everywhere: from automotive and electronics to solar systems. Need protection from overcharging.
• Lead-acid. You can buy a lead-acid battery inexpensively, which explains the popularity of this drive. It is used for powering portable battery consumers, for autonomous electrification, solar stations. Characterized by low self-discharge. Sensitive to deep discharge.
• Gel . They are classified as lead-acid, but have a jelly-like electrolyte that will not leak even if the case is damaged. Gel batteries are durable and designed for hundreds of charge-discharge cycles. They do not apply to budget devices.
• Nickel-cadmium. They can be purchased for electric vehicles, water and air transport, as a backup power source. Durable models, serviceable (with the ability to top up electrolyte) and maintenance-free. They can withstand low temperatures (down to -20 degrees) and are suitable for working in extreme conditions. But you need to remember that this type of battery has a “memory effect”.
• Nickel metal hydride. Such units can be purchased for powering lighting fixtures, autonomous power supply systems, and electric machines. The capacity is 40% higher than a nickel-cadmium battery and has less “memory effect”. The disadvantages include a fairly high percentage of self-discharge.

When deciding to buy a battery, focus on your individual needs. Choose a battery of the right size to cover the charging needs of your devices.

Proper use and care of batteries

To buy a battery in Kyiv and other cities and not be disappointed, carefully study the operating features of the drive and follow the rules of safe operation.

• Monitor the integrity of the housing in order to detect a leak of toxic electrolyte in time.
• Regularly clean the terminals and contacts from oxides and contaminants to maintain the functionality of the device.
• In serviced batteries, check the electrolyte level and add purified water.
• Install and store the battery away from fire (fireplace, campfire) and sunlight. Avoid overheating, including promptly disconnecting the charger.
• Charge according to the battery type. Drives with different chemical compositions require, accordingly, different approaches to recharging and compliance with individual requirements.
• Charge the battery with the charger included. Charging is carried out at positive room temperature (about +18 degrees).
• Take care of the environment and dispose of batteries only in designated areas.

Even if you decide to buy a battery in Kyiv or another city, but do not yet use the energy storage device as unnecessary, charge it at least once a year. Inspect the unit regularly to identify problems in time.
