Yuasa HJ-S55D23L AUXILIARY CAR BATTERY 12V 57AH, 12 Months Warranty

Modern vehicles fitted with advanced energy management systems place considerable demand on auxiliary battery capacity, requiring a unit capable of sustained deep-cycle performance without compromising cranking reliability. The Yuasa HJ-S55D23L is a 12V 57Ah AGM auxiliary battery engineered to meet these exacting requirements, delivering 430 cold cranking amps alongside stable voltage supply for vehicle electronics, lighting, and accessories. Yuasa manufactures this battery within its HJ-S auxiliary range, applying absorbed glass mat technology to produce a sealed, maintenance-free unit. The AGM construction immobilises the electrolyte within glass fibre separators, eliminating free acid and enabling the battery to operate in any orientation without risk of spillage. Vibration resistance is rated V2, making the HJ-S55D23L suitable for use in demanding conditions including rough terrain. Low self-discharge characteristics further support auxiliary duty cycles where the battery may experience extended periods between charge events. The HJ-S55D23L occupies a JIS D23 AGM case measuring 220mm 171mm 227mm and weighs 12.7kg with acid. It is fitted with T1 terminals and carries standard 0 polarity. Charge retention is rated C2 and water loss W5. No direct cross-reference codes are listed; suitability for start-stop applications is not confirmed and should be verified against the product label prior to fitment. The HJ-S auxiliary range includes the HJ-S34B20R, HJ-S46B24R, and HJ-S65D26L-B, offering alternative capacities and case sizes to suit different vehicle requirements.
