A. The Rolls S2-1620GEL has a rated capacity of 1828Ah at the 20-hour discharge rate (C20). At the 10-hour rate (C10), the rated capacity is 1620Ah.
A. The S2-1620GEL is a 2-volt cell. Multiple cells are typically connected in series to build the required system voltage for a given installation.
A. The S2-1620GEL uses an immobilised GEL electrolyte combined with tubular positive plate technology. This OPzV construction eliminates free liquid electrolyte, reducing maintenance requirements and acid stratification risk.
A. Polarity must be confirmed by checking the label on the individual unit prior to installation. Do not assume terminal orientation from photographs or generic diagrams.
A. Yes. The OPzV GEL design is well-suited to cyclic and standby stationary applications including off-grid solar, UPS systems, and industrial energy storage where deep discharge capability and low maintenance are required.
A. As a valve-regulated GEL battery, the S2-1620GEL does not require electrolyte top-up under normal operating conditions. However, periodic inspection of connections, housing, and charging parameters is recommended.
A. No confirmed cross-reference codes are available for the S2-1620GEL. If you are replacing a battery from another manufacturer, please contact PartsForMachines with the existing part number to confirm compatibility.
