## Summary description

Sealed AGM lead-acid battery voltage VEL12-28 with 12V nominal voltage and 28Ah capacity. Designed for long-life standby and cyclic applications, the battery features valve-regulated AGM construction and a manufacturer-stated 15-year service life. Suitable for UPS, alarm systems, emergency lighting, telecom and renewable energy backup where reliable, maintenance-free power is required.

## Long description

The sealed AGM lead-acid battery voltage VEL12-28 provides a nominal voltage of 12 V and a rated capacity of 28 Ah. Built with valve-regulated AGM technology, this battery is designed for long-life standby and cyclic applications where maintenance-free, reliable power is required. The manufacturer states a service life of up to 15 years, making the VEL12-28 suitable for installations that demand extended operational life and predictable performance.
Advantages
The AGM construction ensures recombination of gases and eliminates the need for topping up electrolyte, offering a maintenance-free experience. Valve regulation improves safety by controlling internal pressure, while the sealed design prevents leakage and allows flexible mounting orientations. The battery delivers stable voltage output and improved cycle durability compared with standard flooded lead-acid cells, making it appropriate for both standby power and frequent discharge/charge cycles.
Suitable for
 Uninterruptible Power Supplies (UPS) for small to medium systems
 Security and alarm systems
 Emergency and exit lighting
 Telecommunications and network equipment backup
 Renewable energy storage for small installations and backup circuits
Key specifications
 Nominal voltage: 12 V
 Rated capacity: 28 Ah (at standard discharge rate)
 Battery type: Sealed lead-acid, AGM (absorbed glass mat)
 Design life: Manufacturer-stated up to 15 years in float/standby use
 Valve-regulated construction for safety and recombination
 Maintenance: Maintenance-free, no electrolyte topping required
 Typical applications: Standby and cyclic use with good cycle durability
How to use
Install the battery in a well-ventilated, dry environment away from direct heat sources and corrosive materials. Observe correct polarity when connecting to chargers, inverters or equipment and use appropriately rated cable and terminals. For float/standby applications use a charger with an appropriate float voltage and temperature compensation if available; for cyclic use follow the charger manufacturer’s recommended charge profile for AGM batteries. Periodically inspect the battery and connections for tightness and cleanliness; because the battery is sealed, do not open or attempt to service internal components.
Usage recommendations
For best long-term performance, store and operate the battery within the temperature range recommended by the equipment or charger manufacturer, avoid deep discharges when possible, and use a compatible AGM charge algorithm. Replace batteries that show significant capacity loss or fail to hold charge to maintain reliability in backup systems.
