Installation Notes:

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.

NOTE: All of our B19 options have SAE posts, so if you have a Gen 1-3 Toyota Prius, you will need SAE to JIS adapters. Please add those to your order if you don't already have them prior to ordering.
