Yuasa YBX5054 SILVER HIGH PERFORMANCE CAR BATTERY 12V 40AH, 12 Months Warranty

Maintaining reliable engine starts in compact and mid-sized vehicles demands a battery that combines sufficient cold cranking performance with resistance to the vibration and temperature cycling inherent in everyday driving. The Yuasa YBX5054 is a 12V 40Ah silver calcium-alloy battery from the YBX5000 Silver High Performance range, engineered to meet those demands in a physically compact JIS B19 case format. Yuasa manufactures the YBX5000 series using silver calcium alloy plate technology, which reduces water loss and self-discharge compared with standard lead-calcium designs. The result is a battery with improved charge retention, classified C2, and a water loss rating of W4, both indicators of reduced maintenance requirements over the service life. The sealed construction with end-venting resists spills and withstands vibration, contributing to consistent performance across varied operating conditions." The YBX5054 delivers 360A cold cranking performance to EN standard and a 40Ah capacity rated at the 20-hour discharge rate. Physical dimensions are 187mm × 127mm – 223mm (L × W × H) with a mean weight of 9.4kg. The case format is JIS B19. Terminal type is T1/T3 with standard positive polarity (polarity 0). A state of charge indicator and carry handles are included. The recommended charge rate is 2A. Note: start-stop vehicle compatibility is not confirmed – refer to the product label before fitting.
