Yuasa HJ-S34B20R AUXILIARY CAR BATTERY 12V 35AH, 12 Months Warranty

Modern vehicles equipped with advanced infotainment systems, camera arrays, and driver-assistance electronics place sustained demand on auxiliary electrical circuits that a single cranking battery cannot reliably support. The Yuasa HJ-S34B20R is a dedicated 12V 35Ah AGM auxiliary battery engineered to meet that secondary load requirement, supplying stable power to ancillary systems without compromising main-start performance. Yuasa manufactures the HJ-S series to absorbed glass mat (AGM) construction standards, immobilising the electrolyte within a compressed glass fibre separator. This sealed, maintenance-free design eliminates acid stratification, resists vibration damage on rough terrain, and delivers a low self-discharge characteristic that preserves charge during extended vehicle downtime. Cold cranking performance is rated at 272A (EN), and the recommended charge rate is 2A." The HJ-S34B20R occupies a JIS B20 AGM case measuring 197mm × 129mm – 227mm (L × W × H) and weighs 10.5kg with acid. It is fitted with T3 terminals and carries a positive-left polarity designation (polarity code 1). No hold-down clamp provision is incorporated. Prospective fitment should be verified against vehicle manufacturer specifications; start-stop system compatibility is not confirmed – refer to the product label for guidance. No direct cross-reference codes are currently listed for this part. "The HJ-S auxiliary range is also available in the following variants: HJ-S46B24R (PID07093), HJ-S55D23L (PID07096), and HJ-S65D26L-B (PID46577), covering a range of case sizes and capacities for differing auxiliary applications. This battery is supplied with a 12-month manufacturer warranty. Standard delivery: 1–3 working days within UK mainland. 30-day returns.
