Sealed AGM Lead-Acid Battery europower EPS 12V 65Ah (model EPS 65-12, long service life 8–12 years)

The europower EPS 12V 65Ah sealed AGM lead-acid battery delivers 12 volts and 65 ampere-hours in a valve-regulated, maintenance-free design. The absorbed glass mat (AGM) construction reduces water loss, lowers self-discharge and ensures stable output for prolonged standby and cyclic use. The manufacturer rates expected service life at 8–12 years when operated within recommended temperature and charging conditions, making this battery suitable for applications that require dependable reserve power over an extended period.

Advantages

The sealed AGM design provides leak-proof operation and requires no regular maintenance, while the valve-regulated construction maintains safe internal pressure and minimizes gas emissions. AGM separators deliver low internal resistance for reliable high-current delivery during discharge. Low self-discharge and good charge acceptance enable long storage intervals and efficient recharging from chargers or in renewable systems. The battery's robust construction supports consistent performance in standby power systems and moderate cyclic use.

Suitable for

• Uninterruptible power supplies (UPS) and backup power units
• Telecommunications equipment and emergency power systems
• Renewable energy storage for small solar or wind installations
• Security and alarm systems, access control
• Standby power for medical devices and industrial control systems

How to use

Install the battery in a well-ventilated, dry location on a stable surface, observing polarity and connection torque recommendations of the system in which it is used. Use a compatible charger or charging system configured for sealed lead-acid AGM batteries and follow recommended float and cyclic charge voltages to maximize service life. Avoid deep discharges beyond the equipment specifications and restore charge as soon as practical after use. Maintain ambient temperature within the equipment’s recommended range to prevent accelerated ageing and capacity loss.

Usage recommendations

For optimal longevity, maintain a stable float charge when used in standby applications and avoid prolonged storage at high state-of-discharge. Periodically inspect terminals for secure connections and clean corrosion from contacts if present. When integrating into battery banks or parallel strings, match age, type and state of charge among cells and follow manufacturer guidelines for equalization and charging to ensure balanced performance.
