## Long description

The Sealed AGM Rechargeable Battery Long 12V 18Ah WP18-12NSHR is a valve‑regulated lead‑acid battery designed for standby and cyclic applications. It provides a nominal voltage of 12 V and a capacity of 18 Ah in a maintenance‑free, sealed construction. The absorbed glass mat (AGM) technology minimizes electrolyte leakage and reduces self‑discharge, making the battery suitable for use in uninterruptible power supplies (UPS), alarm and access control systems, emergency lighting, telecommunication equipment and other backup power installations.
Advantages
This sealed AGM battery offers maintenance‑free operation with a valve‑regulated design that controls gas recombination and reduces the need for periodic servicing. The compact rectangular housing and robust terminals enable reliable installation in confined spaces. AGM construction provides low internal resistance for effective charge acceptance and stable discharge performance under both standby and cyclic conditions. The battery is designed for safe operation with limited gas emission and low self‑discharge during storage.
Suitable for
Uninterruptible power supplies (UPS) for computers and network devices
Alarm systems and access control panels
Emergency and exit lighting units
Telecommunications and networking equipment
General backup power in small server cabinets and control cabinets
Key specifications
Nominal voltage: 12 V
Rated capacity: 18 Ah (ampere‑hours)
Technology: Sealed lead‑acid, AGM (absorbed glass mat)
Design: Valve‑regulated, maintenance‑free
Typical applications: Standby and cyclic operation
Discharge performance: Low internal resistance for reliable charge acceptance
How to use
Install the battery in a dry, well‑ventilated enclosure with terminals accessible for connection. Observe correct polarity when wiring to the device or battery pack and use appropriately sized cables and connectors for the expected load. For standby applications, keep the battery connected to a compatible float or standby charger that regulates voltage to prevent overcharge. For cyclic use, apply a charger with a suitable charging profile for sealed lead‑acid AGM batteries to maximize service life. Avoid deep discharges and follow the equipment manufacturer’s installation and safety instructions.
Usage recommendations
Store and operate the battery at ambient temperatures recommended for sealed lead‑acid batteries to minimize capacity loss; periodic charging during storage is advised to prevent deep discharge. Replace batteries as part of preventive maintenance if capacity degrades below the required runtime for the application.
