Installation Notes:
1. Unlike AGM and other lead acid batteries, Ohmmu batteries do not off-gas toxic fumes, so they can be safely installed without using the 12V battery vent tube in the vehicle.
2. 2022 and later models are NOT compatible (i.e. any vehicles with revised 15.5V low voltage battery systems).
3. Please note our Model X 12V battery (Li-B19R/Na-B19R) has SAE terminals (JIS to SAE adapters are no longer needed), and now has the same terminal orientation as the OEM battery. In addition, our redesigned slimmer case removes the need for white lithium grease to be applied during the process, making the install even easier.
