Our electropolished battery boxes are available in group 24, 27, and 30/31. While the base size remains the same for the new batch of ‘wonder batteries’ the ‘J’ bolts which hold the top bracket are available in three lengths, to accommodate Optima, etc.
The boxes are made to mount on either the floor or the side of a stringer.
