Guide To UPS Battery Basics, Maintenance & Sustainability
1. Battery Basics
1. Battery Basics
1. WHAT ARE THE MAIN TYPES OF UPS BATTERIES USED IN THE INDUSTRY?
Uninterruptible Power Supply (UPS) systems primarily rely on batteries to ensure seamless power continuity. The main types of UPS batteries dominating the industry include:

- SLA (Sealed Lead Acid): Completely sealed, these batteries are versatile, easy to install, and can operate in any position.
- AGM (Absorbent Glass Mat): Here, the electrolyte is absorbed by fine fiberglass mat, making them spill-proof. They offer quick charge times and a longer service life.
- Lithium-ion: Rapidly gaining traction in the UPS industry, lithium-ion batteries are known for their extended lifespan, compact size, and reduced weight. They also possess a higher energy density and can endure more charge/discharge cycles compared to traditional lead-acid batteries.
2. HOW DOES A UPS BATTERY WORK?
A UPS battery serves as the backbone of an Uninterruptible Power Supply system. Its primary role is to provide instantaneous power during electricity outages, ensuring there's no interruption to the connected devices.
When the main power source is functioning correctly, the UPS system charges the battery, keeping it ready to take over in case of a power cut. Once there's a disruption in the main power source, the UPS system immediately switches to its internal battery, preventing any downtime.
The power stored within the battery is in DC (Direct Current) form. However, most electronic devices require AC (Alternating Current). The UPS, thus, has an inverter that converts this stored DC power into AC power, suitable for running the connected devices. This transition happens in milliseconds, ensuring that devices like computers don't shut down suddenly, protecting data and hardware.
