A. The S2-336GEL has a rated capacity of 378Ah at the C20 discharge rate and 336Ah at the C10 rate. These figures reflect the charge available under the respective standardised discharge conditions and are the primary capacity references for system design.
A. The S2-336GEL is a single 2-volt cell. It is intended for use in series-configured battery banks to achieve the system voltage required by the application, such as 24V, 48V, or higher, depending on the number of cells connected.
A. The OPzV range uses a combination of immobilised gel electrolyte and tubular positive plate construction, designed and manufactured to DIN standards. The positive grid is die-cast, and Rolls' patent gel formula is used to minimise electrolyte stratification and internal gassing throughout the service life.
A. Yes. As a valve-regulated gel battery, the S2-336GEL is sealed and operates maintenance-free. The immobilised gel electrolyte eliminates the need for water topping and significantly reduces gassing, making it suitable for installations where routine maintenance access is restricted.
A. The battery measures 145mm in length, 206mm in width, and 382mm in height including the terminal. It weighs 28kg. These dimensions should be used when specifying battery racking, enclosures, or transport logistics.
A. Polarity and terminal configuration must be verified against the product label supplied with the unit prior to installation. PartsForMachines recommends checking the label directly, as this is the definitive reference for this SKU.
A. The S2-336GEL is designed for stationary deep-cycle applications including solar photovoltaic energy storage, uninterruptible power supply (UPS) systems, telecommunications infrastructure, and other commercial or industrial installations requiring reliable, maintenance-free energy storage.
A. Start-stop compatibility has not been confirmed for this product. It is a stationary deep-cycle cell and is not intended for automotive cranking applications. Refer to the product label for any further application guidance.
A. The range includes ten models spanning from the S2-224GEL (224Ah) through to the S2-1620GEL (1,620Ah) at the C20 rate. Intermediate options include the S2-280GEL, S2-405GEL, S2-486GEL, S2-567GEL, S2-690GEL, S2-920GEL, S2-1150GEL, and S2-1380GEL, allowing precise scaling of battery bank capacity.
A. Standard delivery is 1–3 working days to UK mainland addresses. A 30-day returns policy applies. For delivery to non-mainland UK locations or for bulk order enquiries, please contact PartsForMachines directly prior to placing your order.
