Yuasa YBX7053 (N55) 12V 45Ah 450A EFB Start Stop Battery, 12 Months Warranty

Modern start-stop vehicles demand a battery capable of withstanding repeated charge and discharge cycles during engine-off coasting and idle stop events – a duty cycle that rapidly degrades conventional flooded technology. The Yuasa YBX7053 is an Enhanced Flooded Battery (EFB) from the YBX7000 series, engineered specifically to meet these elevated cycling demands at a mid-range price point. Yuasa's EFB construction uses a polyester scrim mat applied directly to the positive plate, increasing active material retention and charge acceptance compared to standard flooded batteries. The sealed design achieves a W3 water-loss rating, C2 charge retention classification, and V3 vibration resistance, while the M1 endurance rating confirms suitability for demanding duty cycles. The recommended charge rate is 3A. The YBX7053 delivers 12V, 45Ah capacity at the 20-hour rate, and 450A cold cranking performance to EN1 standards. Physical dimensions are 238mm (L) × 128mm (W) × 227mm (H), with a mean weight of 13kg including acid. The case conforms to JIS B24 EFB (N55) classification with a 0 (positive left) polarity layout and T1/T3 terminal configuration. No cross-reference codes are held; compatibility with specific start-stop systems should be confirmed by reference to the product label. The YBX7053 is part of the broader YBX7000 EFB Start Stop range. Related variants available on site include YBX7100, YBX7027, YBX7005, YBX7054, and YBX7055, covering alternative capacities and fitments within the same technology tier. This battery is supplied with a 12-month manufacturer warranty. Standard delivery: 1–3 working days within UK mainland. 30-day returns.
