Eric Schmidt, former CEO of Google recently quipped that if we do not reinforce our energy needs with new generation and conditioning methods, the AI data centres could drain the energy and there could be a crisis! In such a scenario, reliable power backup becomes critical to keeping your devices running smoothly without interruption. Whether you manage servers, run a home office, or operate sensitive equipment, an Online UPS with battery backup offers the best protection against power outages, voltage fluctuations, and power surges that could harm your equipment and important data.
Here, we explain why choosing an online UPS with a long-lasting battery and pure sine wave output is a smart investment, and where to find the best UPS systems for sale today.

What is an Online UPS and How Does It Work?
An Online UPS provides clean, uninterrupted power to connected devices. The best topology used is double-conversion – that constantly converts incoming AC power to DC for charging your batteries and then back to AC required for your equipment
Unlike offline or line-interactive UPS systems, the online UPS ensures there is zero transfer time during power outages, meaning your devices never experience even a brief power interruption.

Why Long Battery Backup Matters
- Extended Runtime: Long battery life means your devices can keep running for minutes or even hours during outages—enough time to safely save work, shut down equipment, or switch to alternative power sources.
- Critical for Areas with Frequent Power Cuts: If you live or operate in a region with unstable power supply, a UPS with extended battery backup is essential.
- Supports Larger Loads: Longer battery life is particularly important if you need to back up multiple devices or larger equipment.

Importance of Pure Sine Wave Output
A pure sine wave UPS ensures that your valuable devices are delivered with smooth, clean power that’s not different from utility power. This is especially vital for:
- Sensitive electronics like medical devices, audio/video equipment, and high-performance computers
- Devices with active power factor correction (PFC) power supplies
- Reducing electrical noise, heat, and risk of equipment damage
Normally, most Online UPS systems provide pure sine wave output by design, making them a preferred choice for critical applications.

How to Choose the Right Online UPS for Your Needs
When shopping for an online UPS with long battery backup, consider these key factors:
- Power Capacity (VA and Watts): Make sure the UPS can handle the total load of your devices. UPSs are specified in VA whereas you need to convert that to Wattage by considering output pf as 0.8
- Input and Output phases: Check and decide whether you need a single phase or three phase UPS. This depends both on your input voltage phases and the input type required for your equipment.
- Battery Runtime: Check how long the UPS can power your equipment during an outage. This depends on the battery capacity and the charging current that the UPS can provide.
- Expandable Batteries: Some models allow connecting extra battery packs to increase backup time.
- Pure Sine Wave Output: Essential for sensitive or high-end electronics.
- Additional Features: LCDisplay, Touchscreen graphic LCD, WiFi/RS485/SNMP/Ethernet interfaces, Static bypass switch, Parallel Redundancy etc are some desirable features.
