Sealed AGM Battery voltage VEL12-100 12V 100Ah, long life (15 years)

The sealed AGM battery voltage VEL12-100 12V 100Ah is a valve-regulated lead-acid battery engineered for long service life and maintenance-free operation. Its absorbed glass mat (AGM) construction provides low internal resistance, reliable DC output and deep-cycle capability appropriate for repeated charge and discharge cycles. The battery is spill-proof and suitable for installation in enclosures, cabinets and confined spaces where a stable 12V supply is required for backup power, renewable energy systems and telecommunications equipment.

Advantages

The battery offers a long design life of up to 15 years under recommended float conditions, reducing the need for frequent replacement. Sealed AGM design eliminates regular electrolyte maintenance and minimizes the risk of leaks, while the robust lead-acid chemistry provides dependable performance across a range of temperatures. Low self-discharge and good charge acceptance support reliable standby and cyclic use, and the compact, service-free format simplifies installation and handling.

Suitable for

• Backup power for UPS systems and emergency lighting
• Solar and other renewable energy storage in small to medium off-grid setups
• Telecommunications equipment and base stations
• Security systems, access control and alarm installations
• Cabinet-mounted DC power for industrial and automation devices

How to use

Install the battery in a well-ventilated, dry enclosure or cabinet on a stable, non-conductive surface. Connect to the DC system observing correct polarity and using appropriately rated cables and fuses. Charge the battery with a compatible regulated charger or charge controller configured for sealed lead-acid/AGM chemistry and follow recommended float and cyclic charge voltages. Avoid prolonged deep discharges where possible to maximize service life, and perform periodic visual inspections for secure connections and any signs of damage.

Usage recommendations

For longest life, maintain the battery on a controlled float charge when used in standby applications and avoid high-rate continuous discharge. Use a charger or solar charge controller with AGM profile settings, monitor system voltage periodically, and ensure ambient temperature remains within the manufacturer’s recommended range. Store batteries at a partial state of charge and recharge after extended storage to prevent capacity loss.
