## Summary description

12V 150Ah QOLTEC gel deep cycle battery designed for long-lasting, maintenance-free use in stationary, solar, and backup power systems. Gel electrolyte prevents leakage and enables stable performance under deep discharge and frequent cycling. Suitable for off-grid setups, UPS, telecom and mobility applications where reliable, vibration-resistant power storage is required.

## Long description

QOLTEC 12V 150Ah gel deep cycle battery is designed for stationary and renewable energy applications that require long-lasting, maintenance-free energy storage. The gel electrolyte construction prevents leakage and improves tolerance to deep discharge and repeated cycling. This battery is suitable for use in solar off-grid systems, backup power installations, UPS units, telecom sites and applications with vibration or irregular load profiles where a stable 12V power source is needed.
Advantages
The gel design provides sealed, maintenance-free operation and reduces the risk of electrolyte spillage, while offering enhanced resistance to deep discharge and frequent cycling. The 12V 150Ah capacity delivers extended runtime in off-grid or backup scenarios and supports predictable performance over extended periods. Construction intended for stationary and renewable setups improves vibration resistance and reduces the need for ventilation or regular topping-up of cells.
Suitable for
 Solar photovoltaic off-grid and hybrid systems
 Stationary backup power and emergency lighting
 Uninterruptible Power Supplies (UPS) for moderate runtime
 Telecommunication equipment and remote sites
 Electric mobility platforms and other vibration-prone applications
Key specifications
 Nominal voltage: 12 V
 Nominal capacity: 150 Ah
 Electrolyte type: gel (sealed, valve-regulated)
 Design: deep cycle, maintenance-free
 Intended use: stationary and renewable energy storage
 Performance: tolerant to deep discharge and repeated cycling
How to use
Install the battery on a stable, non-conductive surface in a well-ventilated indoor or sheltered outdoor location protected from direct sunlight and extreme temperatures. Connect using appropriate cable size and corrosion-resistant terminals, observing correct polarity. For renewable systems, pair the battery with a compatible charge controller and inverter sized for the system load. Regularly monitor charge state and system voltages with a battery monitor or controller to avoid prolonged deep discharge beyond the manufacturer-recommended limits.
Usage recommendations
For longest service life, maintain the battery within recommended temperature ranges, avoid continuous deep discharge where possible, and use a charge profile suitable for gel batteries (regulated voltage with appropriate float and bulk settings). Periodic inspection of connections and controlling charge/discharge cycles improves reliability in stationary and renewable installations.
