Yuasa YBX5056 SILVER HIGH PERFORMANCE CAR BATTERY 12V 40AH, 12 Months Warranty

Conventional lead-acid starter batteries fitted to older and mid-range vehicles often struggle to deliver consistent cold-weather cranking performance and suffer from elevated self-discharge during prolonged storage. The Yuasa YBX5056 is a 12V 40Ah silver calcium-calcium alloy battery from the YBX5000 Silver High Performance range, engineered to address both concerns in a single, cost-effective replacement unit. Yuasa manufactures the YBX5000 series using silver-calcium alloy plate technology, which reduces water loss, lowers self-discharge rates, and improves charge acceptance compared with standard calcium batteries. The sealed construction resists electrolyte spillage and offers enhanced vibration tolerance, making it suitable for vehicles operated on uneven surfaces. A state-of-charge indicator provides a quick visual check of battery condition without the need for additional test equipment. The recommended charge rate is 3A. The YBX5056 measures 187mm (L) × 137mm (W) × 225mm (H) and weighs 9.4 kg with acid. It delivers 360A cold cranking performance to the EN standard, supporting reliable engine starts in low temperatures. The battery features T1/T3 terminal types and polarity 0 (positive terminal on the left). The case conforms to JIS B19 and B1 dimensions with a B1 hold-down specification.
