Lead acid batteries

By their structure, lead-acid batteries are a container containing an electrolyte - a solution of distilled water and sulfuric acid. The electrodes are in the form of plates. Some plates are made of lead dioxide, others are made of sponge lead. The potential difference appears during the interaction of the electrolyte and the electrodes. When an external load is connected to the electrodes, lead oxide interacts with sulfuric acid. This device is worth buying to charge various consumers.

Reliable and productive: the advantages of lead-acid batteries

To power computer equipment, mobile phones, security and fire alarms, household and specialized equipment, you can buy lead-acid batteries. This model has such advantages.

1. Low cost. Budget models are cheaper to buy due to simple production technology. In the Etsenergy store the price starts from 172 UAH.
2. Relatively low self-discharge . If you don't use the unit for a long time, it loses relatively little charge. For example, a year of inactivity is 40% of the lost charge, which is less than that of nickel-cadmium batteries.
3. Easy to maintain. There is no need to add electrolyte. As for the charging time, depending on the model, it takes from 8 to 16 hours.
4. Light weight. Small-sized units are transportable and do not cause inconvenience during storage. For example, LogicPower AK-LP4158 weighs 0.8 kg with dimensions of 100x47x70 mm.
5. Due to the low internal resistance, the device can withstand current surges. With proper use, the service life is 5 years or more.

Cost-effectiveness and ease of use are the main advantages for which it is worth buying lead-acid batteries in Kiev and other cities of Ukraine. The models are equipped with a reliable housing that protects the electrolyte from leaks and makes the device safe for use.

Lead-acid batteries: the optimal solution for high loads

If you decide to buy lead-acid batteries, consider some features of their operation. Thus, it is not advisable to use such devices at sub-zero temperatures, since the battery capacity decreases. Also, follow the correct charging mode to avoid overheating. Store only when charged.

When purchasing a unit, consider the following characteristics.

• Number of charge-discharge cycles. Before purchasing lead-acid batteries, you should know in advance how long of use you can expect.
• Dimensions and weight. Before you buy a unit, consider where you will place it and how often you plan to transport it. Lightweight units have a smaller capacity, but are easily transported.
• Capacity. This parameter indicates how many hours the battery can power consumers. You should buy a device that will power all consumers. The voltage depends on the capacitance.

Also remember that this device will provide 100% power if you store it in rooms without sudden temperature changes. Also regularly clean the terminals of any contaminants to ensure efficient current flow.

In the Etsenergy store you can buy lead-acid batteries in Kiev or any other city in Ukraine. We will deliver the goods to any point in Ukraine and provide the necessary consultations so that you choose the battery that suits your needs.

History and technological features of lead-acid batteries

Initially, lead-acid batteries were a fairly primitive device, with spiral-shaped plates that were dipped in a sulfur solution. But the invention had a significant drawback: a very low capacity, therefore, from a practical point of view, the use of such a battery was not advisable; accordingly, it was not profitable to buy it for industrial and domestic purposes.

But science did not stand still, and the mechanism underwent a number of improvements. In particular, lead oxides began to be applied to the records, which improved the energy intensity indicator. Later, the mechanism was improved again: a spreadable lattice design began to be used, and the lead electrodes themselves were produced with the addition of antimony.

Now you can buy lead-acid batteries with a sulfur-based electrical conductor. When charging a battery, lead oxide begins a chemical reaction with sulfuric acid. In turn, metallic lead undergoes an oxidation reaction and turns into lead sulfate. During discharge, another process occurs: the cathode is reduced to lead dioxide, and oxidation occurs at the anode.

Care and maintenance of lead-acid batteries: how to extend their service life

Now you can buy lead-acid batteries, serviced and maintenance-free. In the first case, purified water is added to the structure and the density of the electrolyte is controlled. Maintenance-free models are housed in a completely sealed housing. Both batteries, manufactured according to all technological standards, are safe for use and designed for long-term use for both domestic and industrial purposes.

It’s easy to buy such a device, because it is in great demand. But do not forget that for such an energy storage device to work, sulfuric acid is needed. This is a toxic substance that requires increased precautions. To help lead-acid batteries last longer and be as safe as possible, follow a few tips for caring for your energy storage device.

• Check the integrity of the housing regularly. There should be no mechanical damage on it: chips, cracks, deep scratches.
• When you decide to buy an energy storage device, always keep the technical openings of the battery clean, clean the case from dust and dirt to prevent overheating.
• Clean oxidized terminals. Carefully remove plaque with a brush, knife or special cleaning solution. Be careful not to damage the terminals.
• Monitor the electrolyte level. Productivity directly depends on this. You can control the level and add distilled water in serviced devices with special holes.

If you are planning to buy lead-acid batteries in Kyiv and other cities, you need to learn how to charge the device correctly. To make the unit last longer, avoid deep discharge - it destroys the electrode grids. Monitor the charging current. The higher the current used for charging, the faster the device will lose its functionality, so it is better to charge with moderate currents.

Now it is not difficult to buy lead-acid batteries in Kyiv and other cities of Ukraine. But to make the device last longer, follow the manufacturer’s recommendations for charging and maintaining the battery. In particular, observe the temperature conditions necessary for the normal functioning of the battery.
