Endurance Energy 12V 50Ah 450A EN Low-Profile Starter Battery - Part Number: 585550450G
The Endurance Energy 12V 50Ah (450A EN cold cranking) low-profile starter battery (part number 585550450G, manufacturer and OEM references GB5431612BHAD, GB 54316-12(BHAD), GP 50-175, GP50175) is an authentic OEM-grade compact starting accumulator engineered for passenger cars, light commercial vehicles, compact tractors, and professional groundcare machinery requiring a low-profile case height of 175 mm. Built with advanced Calcium/Calcium (Ca/Ca) technology in standard SLI (Starting, Lighting, Ignition) configuration, it is delivered 100% maintenance-free, delivering minimal self-discharge during seasonal storage and superior resistance to cyclic charging. The compact casing (dimensions 208/211 x 175 x 175 mm) features standard European Type 1 conical posts arranged in Layout 0 (positive terminal on the right – RH), a universal B03 / B04 base hold-down ledge, and an EN 50342 class V3 vibration resistance rating to prevent plate shed and internal short circuits under harsh operating conditions. The product is backed by a 3-year warranty.
Key Features & Engineering Advantages
- Special Low-Profile Casing (175 mm Height): Reduced overall height (175 mm compared to standard 190 mm units), specifically designed for low-clearance hoods, under-seat trays, or tight battery compartments.
- Maintenance-Free Calcium/Calcium (Ca/Ca) Technology: High-purity lead-calcium alloy plates prevent electrolyte evaporation, eliminate water replenishment requirements, and provide immediate starting readiness.
- High Cold Cranking Power (450A EN): Excellent energy density and rapid discharge rate tailored to provide crisp and dependable starts for petrol and small diesel engines, even in sub-zero winter temperatures.
- Class V3 Vibration Resistance (EN 50342 Standard): Reinforced plate anchoring and heavy-duty envelope separators deliver superior mechanical endurance against continuous jobsite vibration and terrain shocks.
- Extended 3-Year Commercial Warranty: Industrial-grade manufacturing standards and stringent quality testing ensure long operational life and dependable long-term protection.
- Universal B03 / B04 Base Ledges: Bottom hold-down ledge designed for secure clamping across various automotive and equipment bracket styles on both long and short sides.

Installation Advice & Workshop Notes: Before installation, confirm the compartment dimensions (208/211x175x175 mm) and verify Layout 0 polarity (positive terminal on the right). Switch off the ignition and all auxiliary loads; disconnect the negative ground cable (-) first, then the positive cable (+). Clean the mounting tray and firmly secure the B03/B04 bottom ledge with the factory hold-down bracket to maximize Class V3 vibration damping. Reconnect standard Type 1 conical posts by attaching the positive terminal (+) first and the negative terminal (-) last; do not overtighten terminal clamp bolts and apply a thin layer of technical vaseline or dielectric grease to prevent terminal oxidation. During seasonal machine storage, disconnect cables or attach an intelligent 12V maintenance trickle charger.
