IMPORTANT NOTE: Published dimensions on Optima Group 34 batteries usually list the overall length, width and height which is larger than the inside dimensions of this battery box. The base of the Optima Group 34 box is smaller than the overall width and will fit in the 9-3/4" x 6-1/2" recess on the battery box. If you are not sure, we recommend you measure the base of the Optima Group 34 battery you have to make sure it will fit in the recess, as well as the height to the top of the case, not to the top of the terminals so you can make sure it will fit within the 7" height limit.
