Product Number: S12-128AGM
Variations
Deep cycle applications demand batteries capable of sustained discharge and reliable recovery across hundreds of cycles – conditions that standard lead-acid designs are not engineered to meet. The Rolls S12-128AGM addresses this requirement directly, offering a sealed, maintenance-free AGM platform rated at 12V with a 128Ah capacity at the C100 rate and 115Ah at C20, within the Rolls Series 5 AGM product group (4604).
Manufactured by Rolls Battery Engineering, the S12-128AGM utilises Absorbed Glass Mat technology in which electrolyte is suspended within a glass fibre mat separator. This construction eliminates free acid, prevents stratification, and permits installation in orientations other than upright where application requirements demand it. The sealed valve-regulated design removes the need for water topping and reduces the risk of acid egress during operation.
The battery measures 328mm (L) × 175mm (W) × 237mm (H including terminal) and weighs 32kg. Polarity configuration should be verified against the product label prior to installation. Cross-references include R12-110AGM, LSLC125-12, BAT412101084, BAT412101085, and NCCCLASSA. The technology supports start-stop applications; confirm suitability via the product label.
Variants in the Rolls AGM Series include the S12-116AGM and S12-95AGM, enabling specification to match precise capacity requirements.
Supplied with a 1-year manufacturer warranty. Delivery: pallet shipment, typically 3–5 working days within UK mainland. Contact PartsForMachines for delivery quote. 30-day returns.
A dual-purpose sealed maintenance free AGM battery. This range offers both outstanding value and performance. The AGM-S & AGM-R product lines offer all of the leading design features associated with Absorbed Glass Mat (AGM) technology, offering the user both a lower self-discharge and an increased acceptance to charge current than conventional flooded wet batteries. These batteries offer the perfect solution when looking to replace wet batteries or upgrade existing sealed batteries. Fitted with high-grade brass and lead terminals and featuring convenient carry handles. They also make use of a thick plate design and micro porous glass mat separator to deliver a high deep cycle rate and longer life.
Key Feature:Designed for Leisure applications, balancing dependable starting with steady power delivery.

A. The S12-128AGM is rated at 128Ah at the C100 discharge rate and 115Ah at the C20 rate. These figures reflect different discharge durations and should be matched to the demands of the intended application.
A. The battery uses Absorbed Glass Mat (AGM) technology, in which the electrolyte is held within a glass fibre mat rather than as free liquid. This results in a sealed, valve-regulated, maintenance-free construction that requires no water addition, resists acid spillage, and supports multi-orientation installation where permitted.
A. The battery measures 328mm in length, 175mm in width, and 237mm in height including the terminal. It weighs 32kg. These dimensions should be verified against the available battery compartment before ordering.
A. Polarity must be verified directly from the product label supplied with the battery. Do not assume a standard configuration; confirm terminal positions before making connections to avoid damage to the battery or connected equipment.
A. The AGM technology used in the S12-128AGM supports start-stop system requirements. However, suitability for a specific vehicle must be confirmed against the product label and vehicle manufacturer specifications before installation.
A. The S12-128AGM is cross-referenced against the following part numbers: R12-110AGM, LSLC125-12, BAT412101084, BAT412101085, and NCCCLASSA. Cross-references indicate dimensional or electrical compatibility and should be verified against the original specification.
A. The range includes the S12-116AGM (PID000138160) and the S12-95AGM (PID000138166), offering alternative capacity ratings within the same Series 5 AGM platform. This allows selection based on the precise energy storage requirement of the application.
A. No. As a sealed valve-regulated AGM battery, the S12-128AGM is entirely maintenance-free. There are no vent caps, no electrolyte level checks, and no requirement to add water at any point during the service life of the battery.
A. The S12-128AGM is supplied with a 1-year manufacturer warranty from Rolls Battery Engineering. For warranty claims or queries, contact PartsForMachines with the order reference and details of the fault.
A. The S12-128AGM is dispatched on a pallet due to its size and weight of 32kg. Delivery to UK mainland addresses typically takes 3–5 working days. Contact PartsForMachines directly for a delivery quote prior to ordering. A 30-day returns policy applies.
