Understanding different UPS battery types and their maintenance0478 / June 19, 2019
Uninterrupted Power Supply, or commonly known as UPS, is an electronic device that facilitates power backup and surge protection in case of failure in the primary source of power generation. The portable UPS systems come with batteries which initiate a run of backup power supply to the sources of IT load hence increasing the downtime of various IT equipment. This facilitates an uninterrupted generation of power. This process mostly takes place in case of power cuts, blackouts, and load shedding when the primary source of electricity is cut off.
A UPS, however, differs from a stabilizer, in the sense that the latter is designed to maintain the voltage of particular equipment to a set level. Voltage stabilizer can account for fluctuation in power up to 1 or 2%. Whereas, a UPS system generates power in case of a power failure in the main source. A UPS system otherwise can provide very high levels of voltage stabilization.
The battery of a UPS system is its main component so it is always advised to invest in the UPS System that comes with efficient battery life and battery saver mode to facilitate power optimization along with its primary functions. Following are the different types of batteries available for a UPS system:
Valve Regulated Lead Acid: These are a type of rechargeable batteries found in most UPS devices. This 150 ah battery type is made with a combination of various lead acid cells. These cells have two lead plates hung upon to generate power by converting the lead plates into lead-sulphuric oxide. The procedure is then reversed once the battery is charged. Hydrogen gas is released during the reverse process which may lead to the explosion of this battery but a vent is used right to level up the pressure. To save the lifetime run of this battery, it is advised to store it in a dry and cool atmosphere.
The next type of batteries used are Flooded or Wet Cell batteries. These batteries consist of thick lead plates drenched in electrolyte liquid, such as sulphuric acid. The presence of sulphur makes these batteries extremely corrosive. Hence, one should be careful in handling these batteries. Any negligence can amount to chemical peril while using these batteries. These batteries are to be maintained using distilled water only that too in proper levels.
The final types of batteries found in UPS devices are Lithium Ion batteries. These batteries come in both large and small sizes and own a built-in management unit of their own. These batteries automatically manage their voltage and charge current balance and can also adjust temperature conditions themselves. Such advanced features, however, make these batteries extremely expensive compared to the other two variants. Besides they are also low in energy density.
Opting for the right battery type is beneficial to maintain the standards of performance of the UPS device. The tubuler battery type can also be managed in a better way either manually or with the function of battery saver. Hence, it is always wise to have a detailed comparison as per the buyer’s needs before he plans on his purchase.
