Q 1. What is the C20 capacity of the Rolls S2-3240GEL?

A. The S2-3240GEL is rated at 3660Ah at the C20 discharge rate. The C10 capacity is 3240Ah. C5 and C100 ratings are not published for this model.

Q 2. What voltage is the Rolls S2-3240GEL?

A. This is a 2V cell. Multiple cells are connected in series to achieve the required system voltage, for example 6 cells for a 12V bank or 24 cells for a 48V bank.

Q 3. What technology does the S2-3240GEL use?

A. It uses OPzV tubular positive plate technology combined with an immobilised GEL electrolyte. The valve-regulated sealed construction eliminates routine electrolyte topping-up and significantly reduces hydrogen gassing during normal operation.

Q 4. What is the polarity configuration of the S2-3240GEL?

A. Polarity should be confirmed directly from the product label prior to installation. PartsForMachines recommends always verifying terminal polarity on the physical unit before connecting to any system.

Q 5. Is the S2-3240GEL suitable for solar or off-grid renewable energy storage?

A. Yes. The OPzV GEL range is designed for cyclic deep-discharge and standby stationary applications, making it well suited to solar, wind, and off-grid energy storage systems where regular deep cycling is expected.

Q 6. Does the S2-3240GEL require any maintenance?

A. No routine electrolyte maintenance is required. The valve-regulated sealed design eliminates the need for water topping-up. Terminals should be kept clean and connections checked periodically according to the system operator's maintenance schedule.

Q 7. What warranty does the Rolls S2-3240GEL carry?

A. The S2-3240GEL is supplied with a 3-year warranty from Rolls Battery Engineering, covering manufacturing defects and performance to specification under correct installation and operating conditions.

Q 8. Are there other capacities available in the Rolls S2 GEL OPzV range?

A. Yes. The range includes 2V GEL OPzV cells in capacities from 224Ah up to 1380Ah, with SKUs including S2-224GEL, S2-280GEL, S2-336GEL, S2-405GEL, S2-486GEL, S2-567GEL, S2-690GEL, S2-920GEL, S2-1150GEL, and S2-1380GEL.

Q 9. How is the Rolls S2-3240GEL delivered and what is the returns policy?

A. The S2-3240GEL is dispatched on a pallet and delivered within typically 3–5 working days to UK mainland addresses. Delivery charges are calculated individually due to the size and weight of this product – please contact PartsForMachines for a delivery quote before ordering. A 30-day returns policy applies.

Q 10. What are the physical dimensions and weight of the S2-3240GEL?

A. The battery measures 576mm (length) × 212mm (width) × 799mm (height including terminal). It weighs 240kg and must be handled and installed using appropriate mechanical lifting equipment.
