Sealed AGM UPS Battery QOLTEC 53084 12V 36Ah LongLife

Sealed AGM UPS Battery QOLTEC 53084 12V 36Ah LongLife is a valve‑regulated, maintenance‑free lead‑acid battery designed for uninterrupted power supply (UPS) systems, telecom equipment and general standby applications. The absorbed glass mat (AGM) technology ensures low self‑discharge, stable voltage output and reliable performance in float and cyclic use. The compact, sealed construction allows placement in confined spaces and reduces the need for regular servicing while providing consistent backup power when mains supply fails.

Advantages

The sealed AGM design offers leak‑proof operation and minimal maintenance requirements, making it suitable for long‑term standby installation. LongLife construction and AGM separators improve resistance to vibration and deep discharge compared with conventional flooded batteries. Stable float voltage and low self‑discharge extend service intervals and reduce total cost of ownership in UPS and telecom environments. The battery is ready for direct installation and can be used in both vertical and horizontal mounting positions within the manufacturer’s recommended limits.

Suitable for

• Uninterruptible power supply (UPS) systems
• Telecommunications and network equipment backup
• Alarm and security systems
• Energy storage for small-scale solar or inverter setups
• Replacement of 12V 36Ah sealed lead‑acid batteries in backup systems

How to use

Before installation, check the UPS or backup system manufacturer’s battery specifications and safety instructions. Ensure the battery terminals are free of contaminants and connect using adequately rated terminals and cables, observing correct polarity. Place the battery on a stable, non‑conductive surface in a well‑ventilated area that is protected from extreme temperatures and direct sunlight. After connection, follow the charging procedure recommended by the UPS or charger: use a regulated charger with appropriate float voltage for sealed AGM batteries to prevent overcharging and to maximize service life.

Usage recommendations

For reliable backup performance, perform periodic visual inspections and measure open‑circuit voltage or conduct capacity checks according to the maintenance schedule of your UPS or telecom system. Store batteries charged at recommended voltage levels and at moderate temperatures to limit capacity loss. Avoid deep discharges whenever possible; if deep cycling is required, allow a full recharge cycle to prolong battery life. Dispose of end‑of‑life batteries according to local environmental regulations.
