The Victron Energy AGM 90Ah 12-Volt Deep Cycle Battery is designed for demanding applications that require reliable power supply and long lifespan. This Absorbent Glass Mat battery features very low internal resistance and is particularly suitable for high current discharges in marine systems, recreational vehicles, solar energy storage, and emergency power applications. With a nominal capacity of 90 amp-hours at 12 volts, this battery provides consistent performance over numerous discharge cycles. The AGM design ensures maintenance-free operation without the need for water refilling, while the sealed construction prevents acid leakage and allows for flexible mounting positions. The battery measures approximately 330 mm in length, 172 mm in width, and 220 mm in height, weighing around 26 kg. Its deep cycle capability supports repeated discharge and charge cycles without significant capacity loss, making it ideal for off-grid power systems and applications where reliable energy storage is essential. The robust construction incorporates advanced lead-calcium technology for increased durability and reduced self-discharge during storage periods. This battery maintains a stable voltage output throughout the discharge cycles and demonstrates excellent performance in both high and low temperature environments, operating effectively in the range of -20 °C to 50 °C. The corrosion-resistant terminals and reinforced casing contribute to long-term reliability under various environmental conditions. Victron Energy's quality manufacturing standards ensure consistent performance and extended lifespan, making this battery a reliable choice for critical power applications where failures are not acceptable.
