Suitable for backup power, alarm systems, UPS, telecom equipment and other standby or cyclic applications requiring a compact 12V battery.

## Long description

Sealed AGM rechargeable battery voltage VEL12-18 provides a nominal voltage of 12V and a capacity of 18Ah in a valve-regulated, maintenance-free lead‑acid design. The battery uses absorbed glass mat (AGM) technology to immobilize the electrolyte, which reduces the risk of leakage and enables installation in various orientations. The manufacturer specifies a long service life of up to 15 years when stored and operated according to recommended conditions. The compact dimensions and reliable output make the VEL12-18 suitable for standby and cyclic applications where a stable 12V source is required.
Advantages
The sealed AGM construction ensures maintenance-free operation without the need to add water or monitor electrolyte levels. Valve-regulated design helps control internal pressure and minimizes gas emission under normal use. AGM technology improves vibration resistance and lowers internal resistance for reliable starting and discharge performance. The manufacturer-stated long-life rating simplifies asset planning for systems that benefit from extended replacement intervals.
Suitable for
 Uninterruptible power supplies (UPS) for small to medium systems
 Security and alarm systems
 Telecommunications and network equipment backup
 Emergency lighting and signage
 Cyclic applications in portable or fixed installations requiring a 12V battery
