## Long description

Sealed AGM battery QOLTEC 12V 4.5Ah is a valve-regulated lead-acid (VRLA) rechargeable battery designed for compact, maintenance-free power in standby and cyclic applications. With a nominal voltage of 12 volts and a rated capacity of 4.5 Ah, this battery provides stable DC power for UPS units, alarm and security systems, emergency lighting, and various portable devices. The T1 (4.75 mm) terminals enable straightforward connection to equipment and wiring harnesses, while the sealed AGM construction prevents electrolyte leakage and permits operation in different installation orientations.
Advantages
The AGM design offers low internal resistance, good charge acceptance and reduced self-discharge compared with older flooded lead-acid types. The sealed, valve-regulated construction ensures maintenance-free operation without the need to add water, and it minimizes gas emissions under normal use. Compact dimensions and a steady discharge profile make the battery suitable for tight spaces and predictable backup runtimes. T1 (4.75 mm) terminals provide a reliable and widely compatible electrical interface for common connectors.
Suitable for
Uninterruptible Power Supplies (UPS) for small servers and network equipment
Alarm, access control and security systems
Emergency and exit lighting systems
Portable measurement instruments and handheld devices with compatible voltage
Standby power in compact industrial or telecommunication cabinets
