An uninterruptible power supply, also uninterruptible power source, UPS or battery/flywheel backup, is an electrical apparatus that provides emergency power to a load when the input power source, typically mains power, fails. A UPS differs from an auxiliary or emergency power system or standby generator in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteries, supercapacitors, or flywheels. The on-battery runtime of most uninterruptible power sources is relatively short (only a few minutes) but sufficient to start a standby power source or properly shut down the protected equipment.
A UPS is typically used to protect hardware such as computers, data centres, telecommunication equipment or other electrical equipment where an unexpected power disruption could cause injuries, fatalities, serious business disruption or data loss. UPS units range in size from units designed to protect a single computer without a video monitor (around 200volt-ampere rating) to large units powering entire data centers or buildings.

COMMERCIAL UPS / HOME UPS
A COMMERCIAL UPS, power inverter, or inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC).
The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source (BATTERY).
A power inverter can be entirely electronic or may be a combination of mechanical effects (such as a rotary apparatus) and electronic circuitry.

WE PROVIDE 3 TYPES OF BATTERIES:
LEAD ACID BATTERIES
Despite having a very low energy-to-weight ratio and a low energy-to-volume ratio, its ability to supply high surge currents means that the cells have a relatively large power-to-weight ratio. These features, along with their low cost, makes it attractive for use in motor vehicles to provide the high current required by automobile starter motors. As they are inexpensive compared to newer technologies, lead–acid batteries are widely used even when surge current is not important and other designs could provide higher energy densities.
THESE BATTERIES ARE AVAILABLE IN BOTH FLAT PLATE & TUBULAR FORM.*
Reliable. Over 140 years of development.
Robust. Tolerant to abuse.
Tolerant to overcharging.
Low internal impedance.
Can deliver very high currents.
Indefinite shelf life if stored without electrolyte.
Can be left on trickle or float charge for prolonged periods.
Wide range of sizes and capacities available.
Many suppliers world wide.
The world’s most recycled product.
A VRLA battery (valve-regulated lead-acid battery), more commonly known as a sealed battery (SLA) or maintenance free battery, is a type of lead-acid rechargeable battery. Due to their construction, the Gel and AGM types of VRLA can be mounted in any orientation, and do not require constant maintenance. The term “maintenance free” is a misnomer as VRLA batteries still require cleaning and regular functional testing. They are widely used in large portable electrical devices, off-grid power systems and similar roles, where large amounts of storage are needed at a lower cost than other low-maintenance technologies like lithium-ion.
There are three primary types of VRLA batteries, Sealed VR wet cell, AGM and Gel. Gel cells add silica dust to the electrolyte, forming a thick putty-like gel. These are sometimes referred to as “silicone batteries”. AGM (absorbed glass mat) batteries feature fiberglass mesh between the battery plates which serves to contain the electrolyte. Both designs offer advantages and disadvantages compared to conventional batteries and sealed VR wet cells, as well as each other.
||NO PERIODIC TOPPING UP OF ELECTOLYTE IS REQUIRED
||NO SPILLAGE OF ELECTROLYTEAS IT IS SEALED
||THESE CELLS ARE SUPPLIED IN FULLY CHARGE CONDITIONS, NO INITIAL CHARGING IS REQUIRED
||THESE HAVE VERY LOW SELF-DISCHARGE IN ORDER OF 20% TO 25% OF CONVENTIONAL LEAD ACID BATTERIES
||THESE CAN BE USED AS EITHER VERTICALLY OR HORIZONTALLY. THEY ARE AVAILABLE IN STACKABLE STEEL TRAYS CAPABLE OF BEING MOUNTED ONE OVER THE OTHER. THERFORE, THEY OCCUPY VERY LESS SPACE
||THEY DO NOT EMIT ANY TOXIC, CORROSIVE ACID FUMES, HENCE CAN BE INSTALLED IN THE EQUIPMENT ROOM ITSELF, SAVING THE BATTERY ROOM
||THEY ARE LIGHTER IN WEIGHT BY ABOUT 25% WHEN COMPARED TO CONVENTIONAL LEAD ACID BATTERIES
||THEY HAVE 30% TO 40% LONGER LIFE THAN THE CONVENTIONAL LEAD ACID BATTERIES
LITHIUM – ION BATTERIES
A lithium-ion battery (sometimes Li-ion battery or LIB) is a member of a family of rechargeable battery types in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery. The electrolyte, which allows for ionic movement, and the two electrodes are the constituent components of a lithium-ion battery cell.
Lithium-ion batteries are common in consumer electronics. They are one of the most popular types of rechargeable batteries for portable electronics, with a high energy density, small memory effect, and only a slow loss of charge when not in use. Beyond consumer electronics, LIBs are also growing in popularity for military, battery electric vehicle and aerospace applications. Lithium-ion batteries are becoming a common replacement for the lead acid batteries that have been used historically for golf carts and utility vehicles. Instead of heavy lead plates and acid electrolyte, the trend is to use lightweight lithium-ion battery packs that can provide the same voltage as lead-acid batteries, so no modification to the vehicle’s drive system is required.
High energy density – potential for yet higher capacities.
Does not need prolonged priming when new. One regular charge is all that’s needed.
Relatively low self-discharge – self-discharge is less than half that of nickel-based batteries.
Low Maintenance – no periodic discharge is needed; there is no memory.
Specialty cells can provide very high current to applications such as power tools.
