Rechargeable batteries are special chemical sources of current that are necessary in order to accumulate and then convert an electrical type of energy into a chemical one. The battery can receive energy from all kinds of sources - it can be wind farms, chargers, solar panels, and other installations that are capable of delivering energy at the right time.
If the systems designed for uninterruptible power supply operate directly parallel to the network itself, then the batteries can also be charged from the network themselves, using a special charger. Now there are only a few different batteries, the choice of which depends directly on the system in which it will be used. However, the most commonly used lithium-ion batteries ( https://utem.org.ua/cats /litiy-ionnye_akkumulyatornye_batarei ) and gel batteries.
What are gel batteries?
These products are one of the types of lead-acid batteries, inside of which there is a thickened (or gelled) electrolyte. Such models are completely out of service, however, they have a high recycle life and can be used even at extremely low or high temperatures. In addition, non-standard filling makes it possible to use and install them in any position. As a rule, the largest number of discharge and charge cycles is about 800 pieces, provided the discharges are roughly up to 80 percent.
As for the disadvantages of gel batteries, here we can name their relatively high price, rather large weight and dimensions, as well as sufficient sensitivity to the voltage of the charge itself. As a rule, each model of this type of battery is provided with a guarantee for a period of up to three years.
Lithium-ion battery type
The presented type of battery is the most common today. It can be found in laptops, tablets, e-books, smartphones, and so on. Lithium-ion batteries are most often recommended for purchase due to their long service life, which does not depend on factors that would affect gel batteries. Another advantage of this type of battery is that they have no memory effect, they can last up to twenty years, and their number of discharges and charge is at the level of 2500 cycles. It would seem, what could be better?
In addition, there are also AGMs and lead acid devices, but they are less popular.
