There are three main types of batteries used in uninterruptible power supplies: Nickel-Cadmium, Lead-Acid, and Lithium-Ion. There isn't a single “best†UPS battery technology – the choice should be made on a case-by-case basis.
The main function of the UPS is to store the electric supply whereas the inverter converts the AC power into DC power. The UPS provides the backup supply for very short duration whereas the inverter supplies the power for an extended period.
The distinction between online and offline is conventionally seen as the distinction between computer-mediated communication and face-to-face communication (e.g., face time), respectively. Online is virtuality or cyberspace, and offline is reality (i.e., real life or "meatspace").
The three major types of UPS system configurations are online double conversion, line-interactive and offline (also called standby and battery backup). These UPS systems are defined by how power moves through the unit.
The transfer time is the amount of time a UPS takes to switch from the utility supply to the battery derived supply whenever there is a mains failure. It also refers to the time it takes for the UPS to switch back from the batteries to the mains when the utility power resumes.

True Online UPS (Uninterruptible Power Supply)A True Online UPS provides the ultimate power protection with clean and stable electrical power for critical target loads. This process stabilizes line voltage conditions, frequency regulation and provides uninterruptible power during a power failure event.
The offline UPS is a type of UPS that directly supplies the power to the AC load from the AC mains in normal operation and uses an inverter to power the AC load from the DC battery. Since there are two separate lines of supplies, the output supply must be switched between the two sources.
A UPS System Serves Multiple Purposes:
- Protect against power interruptions.
- Provide adequate power during short-term interruptions and “ride-through†time to convert to backup supply.
- Refine the quality of the power as it reaches your building, office and equipment.
Online UPSBetter voltage regulation. No fluctuations in the voltage, indicating stable voltage quality. The quality of the load voltage is free from distortion. Near ideal electrical output, highest protection against all power irregularities.
The UPS provides pure sine wave to meet the requirement of the equipment, enhancing system efficiency and saving electricity costs.
An online UPS system is usually called double conversion as well because incoming power is converted to direct current (DC) and then converted back to AC.
An easy way to compare battery capacity is to multiply the number of battery blocks by the voltage rating of the battery block (usually 12V but may be 6V, or even 2V) and then multiply this by the Ampere Hour (Ah) rating of the battery.
A double conversion online UPS provides consistent, clean and near perfect power, regardless of the condition of incoming power. Systems with online double conversion topology operate by converting incoming AC power to DC, and back to AC.
A standby UPS is an offline unit that can detect an electrical failure and switch to battery power automatically. The two other UPS categories are Line Interactive and Online devices, with online being the more expensive option. Each type of UPS keeps network devices operational when power is unavailable.
The line-interactive UPS also tends to call upon the batteries more frequently than double conversion UPS modules, shortening the battery life and leading to costly battery change outs. If reliability is key, then double conversion is the best choice for critical loads.
