SW280 LEAD ACID BATTERY

Product Description

The SW280 is a 12V high-rate sealed lead-acid (VRLA AGM) battery, commonly used in UPS systems, emergency lighting, security systems, telecom equipment, and industrial backup power.

It is part of the Yuasa SW series, designed for fast discharge (high power in short duration) rather than long-runtime backup.

Description

The SW280 is a maintenance-free VRLA battery using AGM (Absorbent Glass Mat) technology, where the electrolyte is fully absorbed in fiberglass separators. This makes it spill-proof, leak-resistant, and safe for indoor use.

It is specially engineered for high-rate discharge applications, meaning it can deliver a strong burst of power (around 280W output rating) for UPS and emergency backup systems. It also offers fast recovery after discharge and stable float charging performance.

Key Features

• Sealed maintenance-free VRLA AGM battery
