Q 1. What is the rated capacity of the Rolls S2-2700GEL?

A. The S2-2700GEL has a rated capacity of 3044Ah at the C20 rate and 2700Ah at the C10 rate, making it suited to large stationary battery bank installations requiring sustained energy delivery over extended discharge periods.

Q 2. What battery technology does the S2-2700GEL use?

A. The S2-2700GEL uses OPzV valve-regulated gel technology, combining an immobilised gel electrolyte with tubular positive plates manufactured to DIN standards. The die-cast positive grid and proprietary gel formula reduce electrolyte stratification and eliminate free liquid acid.

Q 3. What are the physical dimensions and weight of the S2-2700GEL?

A. The battery measures 487mm in length, 212mm in width, and 799mm in height including the terminal. It weighs 200kg. Due to its size and weight, it is dispatched on a pallet.

Q 4. What is the polarity configuration of the S2-2700GEL?

A. Polarity should be confirmed by checking the product label directly on the battery prior to installation. PartsForMachines recommends verifying terminal orientation against your system wiring diagram before making any connections.

Q 5. Is the S2-2700GEL suitable for off-grid solar or renewable energy storage?

A. Yes. The OPzV GEL design, with its immobilised electrolyte and low self-discharge characteristics, is well suited to off-grid solar, wind, and other renewable energy storage applications where deep, repeated cycling and minimal maintenance are required.

Q 6. Does the S2-2700GEL require maintenance or topping up?

A. No. As a valve-regulated gel battery, the S2-2700GEL is maintenance-free under normal operating conditions. The sealed design eliminates the need for electrolyte topping up and makes the battery safe for use in enclosed or semi-enclosed installations.

Q 7. What warranty is provided with the Rolls S2-2700GEL?

A. The S2-2700GEL is supplied with a 3-year warranty from Rolls Battery Engineering, providing coverage for manufacturing defects and supporting its use in commercial and industrial applications.

Q 8. Are there other capacity options available in the Rolls OPzV GEL 2V range?

A. Yes. The Rolls OPzV GEL series includes multiple 2V variants to suit different system capacity requirements: S2-224GEL, S2-280GEL, S2-336GEL, S2-405GEL, S2-486GEL, S2-567GEL, S2-690GEL, S2-920GEL, S2-1150GEL, and S2-1380GEL. Contact PartsForMachines to discuss the most appropriate capacity for your installation.

Q 9. How is the Rolls S2-2700GEL delivered and what is the returns policy?

A. Due to its size and weight of 200kg, the S2-2700GEL is dispatched on a pallet. Delivery to UK mainland typically takes 3–5 working days. Contact PartsForMachines directly for a delivery quote. A 30-day returns policy applies.

Q 10. What is the voltage of the S2-2700GEL and how is it used in a battery bank?

A. The S2-2700GEL is a 2V cell. Multiple cells are connected in series to achieve the required system voltage — for example, six cells in series produce a 12V bank, while twelve cells produce a 24V bank. Each cell contributes 3044Ah (C20) to the bank capacity.
