Endurance Energy 12V 30Ah 300A EN Flat Lug Starter Battery - Part Number: 57963030
The Endurance Energy 12V 30Ah (300A EN cold cranking) compact starter battery (part number and genuine OEM reference 57963030) is a high-performance accumulator engineered specifically for compact agricultural machines, commercial ride-on lawnmowers, groundcare equipment, power tillers, and portable generators. Built on standard SLI (Starting, Lighting, Ignition) architecture with heavy-duty flat lug terminals (with integrated bolt eyelet holes), it delivers a robust cold discharge current of 300 A (EN), ensuring dependable cold-engine starts even after extended seasonal downtime. Featuring compact external dimensions of 195 x 130 x 183 mm, a completely smooth B00 base ledge (designed for top hold-down bracket clamping), and an EN 50342 class V2 vibration resistance rating, it protects internal plate packs from severe vibration encountered on rough grounds and heavy machinery engine pulses.
Key Features & Engineering Advantages
- High Cranking Output for Compact Size (300A EN): Delivers substantial starting amperage relative to its 30 Ah nominal capacity, effortlessly overcoming engine compression strokes on petrol and small diesel utility engines.
- Bolt-Through Flat Lug Terminals: Robust flat contact terminals with central bolt holes, preventing terminal disconnection and contact resistance under harsh continuous vibration.
- Class V2 Vibration Resistance (EN Standard): Specially reinforced cell group anchoring designed to withstand the vigorous oscillations of zero-turn mowers, tillers, and vibrating construction equipment.
- Smooth B00 Base Ledge: Clean, flat-bottom casing design engineered for drop-in installation into top-bracket clamped battery trays.
- Standard Polarity Layout 0 (- / +): Right-hand positive terminal orientation for seamless plug-and-play wiring harness connection on leading groundcare machinery.

Hazard Warnings & Safety Measures (CLP Regulation): DANGER: Contains battery acid and corrosive lead compounds. Harmful if inhaled. Causes severe skin burns and serious eye damage. Suspected of causing genetic defects.
• Prevention: Do not breathe dust/fume/gas/mist/vapours/spray. Use only outdoors or in a well-ventilated area. Wash hands thoroughly after handling. Wear protective gloves, protective clothing, eye protection, and face protection (mandatory PPE). Do not eat, drink, or smoke when using this product.
• Emergency Response: IF INHALED: Remove person to fresh air and keep comfortable for breathing; call a Poison Center or doctor if you feel unwell. IF SWALLOWED: Rinse mouth; do NOT induce vomiting; immediately call a Poison Center or doctor. IF ON SKIN (or hair): Take off immediately all contaminated clothing; rinse skin with water or shower; wash contaminated clothing before reuse. IF IN EYES: Rinse cautiously with water for several minutes; remove contact lenses if present and easy to do; continue rinsing.
• Storage & Disposal: Store in a well-ventilated place. Dispose of contents and container in accordance with local, regional, and national hazardous waste regulations.
Installation Advice & Workshop Notes: Before installation, confirm the compartment dimensions (195x130x183 mm) and check the polarity alignment (positive terminal on the right). Turn off the equipment ignition switch; disconnect the negative cable (-) first, then the positive cable (+). Place the battery onto the smooth tray (B00 flat base) and secure the top hold-down bracket firmly to prevent vibration damage. Attach the flat lug terminals using clean bolts: connect the positive cable (+) first, followed by the negative cable (-), and apply a protective film of technical vaseline to guard against corrosion. During extended seasonal storage (e.g. winter), disconnect the leads or connect to a 12V smart maintenance trickle charger in a well-ventilated area.
