U1R - Sodium 12V Battery for Tesla Model S (2012–2021.5)

Meet the next generation of 12V battery technology. The Electrified Series Sodium 12V battery is the intelligent upgrade for owners who want outstanding real-world performance, long-term value, and a battery they can feel good about buying, without paying a lithium premium.

This is a true drop-in upgrade with no maintenance and replaces existing OEM lead-acid units with a battery that is cleaner, lighter, smarter, and built to last dramatically longer. And the climate-proof sodium cells ensure reliable charging and operation in extreme weather environments.
