Sealed AGM battery QOLTEC 53068 12V 150Ah for UPS and backup power

Sealed AGM battery QOLTEC 53068 12V 150Ah is a maintenance-free, valve-regulated lead‑acid battery designed for uninterrupted power supply (UPS) systems, standby backup installations and energy storage applications. The battery delivers a stable 12V output and a rated capacity of 150Ah in a spill-proof, absorbed glass mat (AGM) construction that allows indoor placement without regular electrolyte maintenance. Its designed discharge characteristics support safe shutdowns, emergency lighting and telecom backup where reliable long-duration power is required.

Advantages

The sealed AGM design offers leak-proof operation and reduced gas emission under normal use, eliminating the need for watering or electrolyte checks. With a robust casing and maintenance-free construction, the battery provides predictable performance over long standby periods and is suitable for serial or parallel connection in multi-battery systems to increase voltage or capacity. Low self-discharge and stable voltage delivery ensure extended readiness and smooth integration with inverter and UPS controllers.

Suitable for

• Uninterruptible Power Supply (UPS) systems for servers and network equipment
• Emergency lighting and alarm systems
• Telecommunications and base station backup
• Home and small commercial backup power installations
• Energy storage for off-grid or hybrid systems with inverters

How to use

Install the battery in a well-ventilated, dry indoor location on a stable, non-conductive surface. Connect to the UPS or inverter according to the system manufacturer’s wiring diagram, observing correct polarity and using appropriately rated cables and terminals. For multi-battery configurations, ensure matching capacity, age and state of charge across units before connecting in series or parallel. Use a compatible charger or UPS charging profile designed for sealed lead‑acid AGM batteries to prolong service life. Periodically inspect terminals and connections for corrosion and ensure the unit is kept clean and free of debris.

Usage recommendations

For optimal lifespan, store and operate the battery within the recommended temperature range and avoid deep discharges whenever possible. Regularly check system charge voltage and perform scheduled capacity testing in backup installations to confirm readiness. Replace batteries in matched sets if capacity decline is observed to maintain system reliability.
