Rechargeable AGM Sealed Lead‑Acid Battery Alarmtec BP Series 12V 18Ah for UPS and Backup Power

Alarmtec BP Series AGM 12V 18Ah is a sealed, rechargeable lead‑acid battery engineered for UPS and backup power applications. Its absorbed glass mat (AGM) design provides maintenance‑free operation, reduced self‑discharge and safe, spill‑free installation in upright or horizontal positions. With a nominal voltage of 12 volts and an 18 ampere‑hour capacity, this battery is intended for short‑term power delivery to electronics that require reliable standby power, such as uninterruptible power supplies, emergency lighting and alarm systems.

Advantages

The AGM construction ensures low internal resistance and consistent performance during discharge and recharge cycles. Sealed design eliminates the need for electrolyte maintenance and minimizes gas emission under normal conditions, enabling safer indoor placement. The battery offers stable voltage output suitable for typical UPS and backup loads while its moderate capacity balances runtime and compact physical size. Low self‑discharge allows for extended storage with minimal recharge requirements.

Suitable for

• Uninterruptible Power Supplies (UPS) for servers and network equipment
• Emergency and exit lighting systems
• Intrusion and fire alarm control panels
• Security cameras and surveillance backup
• Small standby power applications in telecom and monitoring devices

How to use

Before installation, verify compatibility with the UPS or backup device in terms of voltage and capacity. Connect the battery to the system following manufacturer wiring polarity and terminal type; tighten connections to the recommended torque to avoid loose contacts. Charge the battery using a charger or charger‑controller configured for 12 V sealed lead‑acid batteries, following the charger manufacturer’s charge voltage and current recommendations. Allow a full charge cycle before placing the battery into active standby service to ensure optimal capacity and life.

Usage recommendations

Store and operate the battery within the ambient temperature range specified by the equipment manufacturer to maximize service life. Avoid deep discharges whenever possible; for standby use, maintain regular inspections and periodic recharge cycles if the battery is kept in long‑term storage. Dispose of or recycle the battery according to local regulations for lead‑acid batteries.
