A. The S2-690GEL has a rated capacity of 785Ah at the C20 discharge rate and 690Ah at the C10 rate. These figures reflect standard deep-cycle discharge performance under controlled temperature conditions.
A. The S2-690GEL uses immobilised GEL electrolyte combined with tubular positive plate technology, constructed to DIN standards. The die-cast positive grid and proprietary gel formula suppress acid stratification and extend cycle life compared to conventional flooded designs.
A. Yes. As a valve-regulated GEL battery, the S2-690GEL requires no routine water addition. The sealed construction recombines evolved gases internally, making it suitable for installations where access for maintenance is limited or where ventilation is restricted.
A. Terminal type and hold-down configuration are not universally specified for this model. Polarity should be confirmed by checking the label on the battery prior to installation. Contact PartsForMachines if you require clarification before placing an order.
A. The S2-690GEL is designed for commercial and industrial stationary applications including renewable energy storage (solar and wind), uninterruptible power supplies (UPS), telecom standby, and off-grid power systems where deep-cycle performance and long service life are required.
A. Yes. The range currently includes ten additional capacities: S2-224GEL, S2-280GEL, S2-336GEL, S2-405GEL, S2-486GEL, S2-567GEL, S2-920GEL, S2-1150GEL, S2-1380GEL, and S2-1620GEL. All are 2V valve-regulated GEL cells from the same OPzV series.
A. The S2-690GEL is covered by a 3-year warranty from Rolls Battery Engineering against manufacturing defects under normal operating and charging conditions. Warranty terms should be reviewed prior to installation to ensure compliance with usage requirements.
A. The S2-690GEL is dispatched on a pallet and typically arrives within 3–5 working days to UK mainland addresses. Delivery costs vary by location; contact PartsForMachines directly for a delivery quote. A 30-day returns policy applies – please contact PartsForMachines to arrange any return.
A. The battery measures 145mm (length) × 206mm (width) × 673mm (height including terminal) and weighs 50kg. These dimensions should be verified against your battery compartment or rack specification before ordering.
A. The S2-690GEL is a single 2V cell. Multiple units are connected in series to build the required system voltage — for example, six cells in series produce a 12V bank, twenty-four cells produce a 48V bank.
