  Vehicles equipped with start-stop systems place exceptional demands on their batteries, requiring reliable charge acceptance during regenerative braking and rapid recovery after each engine restart. The Yuasa YBX7055 is a 12V 40Ah Enhanced Flooded Battery (EFB) developed to meet these requirements within the YBX7000 EFB Start Stop range, offering a capable mid-tier solution for compatible start-stop applications. Manufactured by Yuasa, one of the world’s foremost battery authorities, the YBX7000 EFB range employs Enhanced Flooded Battery technology, which utilises a polyester scrim material bonded to the positive plate. This construction improves charge acceptance, extends cycle life compared to conventional flooded batteries, and provides greater resilience against the deep discharge events characteristic of start-stop operation. The battery also achieves a W3 water loss rating, C2 charge retention classification, V3 vibration resistance, and M1 endurance rating under applicable EN standards. The YBX7055 is housed in a JIS B20 EFB (M42R) case and measures 197mm x- 128mm – 227mm (L x- W x- H), weighing 11.5 kg. It delivers 400A Cold Cranking Amps (EN) and carries a T1/T3 terminal configuration with polarity 1 (positive terminal right). No hold-down bracket is required. The recommended charge rate is 2A. Start-stop compatibility should be confirmed by reference to the product label prior to fitment. No direct cross-reference codes are recorded for this SKU. The YBX7055 is available alongside related YBX7000 EFB variants including the YBX7100, YBX7027, YBX7005, YBX7053, and YBX7054, covering a range of capacities, case formats, and terminal configurations for differing vehicle requirements. This battery is supplied with a 4-year manufacturer’s warranty from Yuasa, providing assurance of build quality and long-term performance. .
