Installation

Tesla Model S – 12V Battery Install
(All Versions: April 2016May 2021)

Installation Notes:

1. Battery Spacer (H-shaped plastic spacer included in box) can be placed underneath battery when installing in battery tray to raise height if needed.

2. 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.

3. June 2021 and later models are NOT compatible (i.e. any vehicles with revised 15.5V low voltage battery systems). If you’re unsure if your vehicle is compatible with Ohmmu batteries, please reference this guide: Tesla | All Models | Identifying Low Voltage Battery System (12V vs 15.5V)
