Battery voltage AGM Long Life 12V 200Ah VEL12-200 (service life 15 years)

Sealed AGM lead-acid battery Long Life 12V 200Ah VEL12-200 from voltage provides stable 12 V output and 200 Ah capacity in a valve-regulated, maintenance-free design. Engineered for long-term standby and cyclic operation, this battery uses absorbed glass mat (AGM) technology to minimize self-discharge and enable safe installation in a variety of orientations. The construction targets applications that require reliable energy storage and a nominal service life of up to 15 years under recommended conditions.

Advantages

AGM construction ensures low internal resistance, consistent voltage delivery and reduced maintenance compared with flooded lead-acid batteries. The valve-regulated design prevents electrolyte leakage and allows safe indoor use. Long rated service life reduces replacement frequency and total lifecycle cost in stationary and renewable energy installations. The battery provides stable performance over extended standby periods and supports moderate cyclic use when charged and discharged within recommended parameters.

Suitable for

• Renewable energy storage (solar and wind hybrid systems)
• Uninterruptible power supplies (UPS) and backup power systems
• Telecommunications equipment and base stations
• Off-grid residential and small commercial energy systems
• Emergency lighting and alarm systems

Key specifications

• Nominal voltage: 12 V
• Nominal capacity: 200 Ah (at specified discharge rate)
• Battery type: Sealed lead-acid, Absorbed Glass Mat (AGM)
• Design: Valve-regulated, maintenance-free
• Expected service life: Up to 15 years under recommended conditions

How to use

Install the battery in a well-ventilated, dry location on a stable surface, ensuring proper polarity connections and secure terminal contacts. Use compatible chargers or charge controllers configured for sealed lead-acid/AGM batteries and follow manufacturer charging profiles to avoid overcharging or deep discharge. Monitor battery voltage and state of charge during cyclic use and maintain ambient temperature within recommended limits to maximize service life.

Usage recommendations

For long service life, keep the battery in a cool environment, maintain a float charge for standby applications, and avoid prolonged deep discharge. Periodically verify terminal tightness and use an appropriate battery management system or charge controller when integrating into renewable or UPS systems.
