The 2024 Jeep Wrangler 4xe employs both a conventional 12V auxiliary battery and a high-voltage battery pack for its plug-in hybrid system; understanding the differences is key to proper maintenance. The 12V battery supports starting, electronics, and low-voltage accessories, while the high-voltage pack stores energy for electric drive operation. Larry H.
