60B19RS Tesla Model X Auxiliary Battery 12V 40Ah, 1 Year Warranty

Product Number: 60B19RS

Tesla Model X vehicles rely on a dedicated 12V auxiliary battery to power essential low-voltage systems independently of the high-voltage traction pack. These systems include lighting, door locks, climate controls, and the central touchscreen display, and must remain operational at all times - making the auxiliary battery a critical component requiring like-for-like replacement. The 60B19RS is a Tesla-branded lead-acid auxiliary battery, purpose-built for the low-voltage architecture used across Tesla's vehicle range. Manufactured to OEM specification, it is designed to integrate directly with the vehicle's battery management system and deliver consistent, dependable performance throughout its service life. Physically, the battery measures 187mm × 127mm × 220mm (L × W × H) and is housed in a B19 case. Terminal placement is Position 1 with standard polarity (Polarity 1), and the hold-down configuration is B00. It carries a 12V nominal voltage and a rated capacity of 40Ah (C20). The cross-reference number is 60B19RS. Start-stop compatibility is not confirmed - please refer to the product label for clarification.
