Battery voltage AGM Long Life 12V 150Ah VEL12-150

The Battery voltage AGM Long Life 12V 150Ah VEL12-150 is a valve-regulated lead-acid battery designed for reliable energy storage in backup power, solar systems, telecommunications and mobility applications. Its absorbed glass mat (AGM) design provides a sealed, maintenance-free construction with deep cycle capability, delivering 12 volts and 150 ampere-hours for both stationary and cyclic use. The battery is intended for installations where long service life, stable output and low self-discharge are required.

Advantages

The AGM construction offers spill-proof, valve-regulated performance that reduces maintenance needs and allows flexible mounting positions. Deep cycle capability supports repeated charge and discharge cycles, while the sealed design minimizes electrolyte loss and corrosion risk. Low self-discharge extends storage intervals, and stable 12 V output ensures compatibility with common inverter, charger and telecom equipment.

Suitable for

• Backup power systems for home and business
• Off-grid and grid-tied solar installations
• Telecommunications and network equipment backup
• Mobility applications such as electric scooters, wheelchairs and small electric vehicles
• Uninterruptible power supplies (UPS) and emergency lighting

How to use

Install the battery in a well-ventilated, dry location on a stable surface, ensuring correct polarity when connecting to chargers, inverters or load devices. Use an appropriate charger or charge controller optimized for lead-acid/AGM batteries and follow recommended charging voltages to preserve cycle life. Avoid prolonged deep discharge below the manufacturer’s recommended depth of discharge and reconnect charging as soon as possible after use to maintain state of health. Observe safety precautions when handling heavy batteries and use insulated tools to prevent short circuits.

Usage recommendations

For optimal longevity, maintain regular charging cycles, avoid sustained high temperatures, and use a charger with an AGM-specific charging profile. Periodically check connections for corrosion or looseness and store the battery in a charged state if not used for extended periods.
