Causes of major damage and storage of batteries in the UPS system
(UPS) or commonly known as "Uninterruptible power supply", commonly used UPS types are generally divided into three main categories according to their operating principles: offline UPS, technology offline UPS Line interactive and UPS online.

A safe energy supply is the foundation for the success and continuity of many businesses, whether it's industrial plants, offices, medical facilities, utilities or data centers.
In this regard, electrical incidents can become very costly, sometimes costing tens of millions of dollars. This is why many businesses need a UPS system.
An important part of UPS is that battery banks provide the energy needed to ensure that a constant flow of clean energy is available for the critical processes that UPS is providing. Parameters to consider when choosing the correct battery system is source, inverter performance, discharge process, charging voltage. These and many other factors need to be carefully considered when selecting and configuring the UPS Battery System.
UPS applications use a variety of batteries; however, lead-acid batteries (LA) are currently the most popular technology. In specific cases with special requirements, nickel-cadmium or lithium-ion batteries are sometimes used. Lithium-ion battery technology is developing rapidly, being used where energy density High and low weight is the main requirement.
Damage Batteries are responsible for 50 to 70 percent of UPS outages. In addition to short circuit reasons, there are three main mechanisms (excluding internal and external short circuits) that reduce the life and performance of the battery system in the UPS.

VRLA batteries discharge themselves, so the available capacity drops even when they are inactive. VRLA batteries must be stored when fully charged, in the original packaging, and a dry, clean and well-ventilated environment.
There should not be any trace of acid on the container surface. Do not stack pallets or batteries together unless instructed by the manufacturer.
As a rule, inside a building, flooded batteries must be stored in waterproof objects with an acid recovery tray. For VRLA Batteries / Batteries, acid collection trays are not required. Batteries must be well protected from metal parts that may cause short circuits, and are protected against accidental damage and falling objects.
During storage, batteries must be properly managed. After a certain period of time from the date of manufacture or the latest date of charging the battery, the battery should be charged according to the manufacturer's instructions. This period depends on aspects such as storage temperature, battery model, etc.
High ambient temperature reduces the time allowed between charges. For this reason, vendor recommendations for each specific battery model should always be followed. Measuring the open circuit voltage of the battery is common to delay the charging process in case the measurement result is higher than the limit.

1. The main causes of battery damage.
#1. Corrosion
Corrosion is often the result of oxidation of positive plates. It reduces the amount of active substance that can participate in reactive chemicals, reduce battery performance and life expectancy. This factor is inevitable. An active battery until subjected to this corrosion has met or exceeded its expected life. Restriction of deep discharge, cycle reduction, moderate temperature operation and overload control are measures to control corrosion.#2. Dry-out
"Dry-out" means reducing electrolysis, greatly affecting battery life and performance. The main reasons for dry batteries are excessive temperature and overload. With higher charging voltages or currents, the gas recombination rate is not enough to compensate for the large amount of hydrogen and oxygen produced. This results in overpressure internal pressure, making the relief valve open. In VRLA, the electrolyte is lost due to the irreversible environment, strongly influencing battery performance and life. In the worst case, it could lead to heat loss, or even fire or explosion.#3. Sulfurization:
In normal chemical reactions when 1 discharge VRLA battery, lead sulfate crystals are deposited on the plates. In the loading mode, they are transferred back to the active substance. If the battery is empty or she is partially charged for a certain amount of time, the lead sulfate crystals become hard and cannot be converted back into lead or lead oxide during charging. This may seriously affect the battery life, performance and capacity, so it is important to fully charge the Battery after each discharge and follow the manufacturer's instructions for voltage settings. Reasonable charging because the charging voltage is only slightly lower than the indication may still cause problems.Learn more: Auto Battery Reconditioning - Learn About the Secret
