The STC Battery Box Mod greatly improves battery performance. It modifies Piper Metal Battery Boxes to eliminate the braided straps and ground connections known for heat generating, high resistance connection. Hard starting and other electrical problems can often be tracked back to poor battery and group connections. Use this inexpensive mod with a new positive and negative cable if your battery box is still mechanically sound. The Battery Box Mod comes with templates to make the cut outs so its very easy to do. The modification also includes the u-shaped flanges a cover plate to seal the old insulator hole and rivets. The flanges accommodate Bogerts Low Loss Copper cables and the entire flange slides in and out of the slots making access to the battery quick and easy. Paperwork includes the FAA/PMA approved STC SA4008NM, AML, Instructions and a sample 337 form entry. |

This is a significant improvement over the old woven aluminum straps, allowing the battery cables to connect directly to the battery. I cant comment if they are worth it on their own as I replaced my cables at the same time, but the box looks better now and I dont have to worry about the 53 year old aluminum straps breaking.
