OPTIMA® Types 3,7
The OPTIMA U 3,7 battery may be shipped with a height adapter installed. It may be needed in one of 2 ways for installation:
1. In vehicles with a top holddown where more height is required, it should be used in its original position.
Dimension changing
Width: 172 mm to 178 mm
Height with bottom adapter: 197 mm to 225 mm
Height with lid adapter: 197mm to 204 mm
2. In some Ford, Lincoln, and Mercury installations (replacing a group 65 battery) the bottom holddown of the battery must be made wider. For these installations, remove the adapter and detach the two strip adapters which are located inside. Snap these strips into the openings on either side of the battery base and discard the remainder. If the adapter is not needed for installation, it may be discarded.
The wing adapters are attached to the ends of the battery to provide a hold down area for DIN H5 applications. Attach the wing adapters by snapping them into the openings on either end of the battery.
