Battery Box Mod STC SA4008NM
The Battery Box Modification 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.
This is Battery Box Modification ONLY, it is best purchased for customers who have already purchased and installed Bogert Aviation's "Low-Loss" Copper Cable Kit (03M-KIT/ STC SA3531NM). To simplify your purchase of Battery Box Modification and Battery Positive and Battery Negative Cables, please click here to purchase all items together (08M-SET).
The Battery Box Mod comes with Adhesive Templates to make the U-Shaped cut outs on the existing battery box. The modification also includes the U-shaped Flanges, a Cover Plate to seal the old insulator hole and Rivets. The Flanges accommodate Bogert’s "Low-Loss" Copper cables; 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.

I am very satisfied with the battery box mod STC. the quality of the materials is good and the installation instructions are easy to follow. Big improvement over the stock battery connections.
Battery Box Mod STC SA4008NM
Great product with good installation instructions. I only wish it came with two sheet metal disks instead of one. My Tri-Pacer battery box had two of the old battery cable pass-through holes versus one. I'll have to make a second sheet metal disk to cover the second hole by using the disk in the kit as a template. Not a big problem, but two sheet metal disks per kit might be a nice option to include during the purchase selection process in future.
Robin, I'm sorry that you didn't get the second plate. Most installations only require one. The PA 20 and PA22 are exceptions to the rule. It is our habit to include the second plate at no charge when we know it is being used on those airplanes. I am glad you are happy with the product otherwise.
The lady that help me place the order on the phone was very knowledgeable and helpful.
The kit was delivered in 48 hours. The materials are very good quality the instructions are thorough.
I am very happy with your product and your service.
Unfortunately I have not finished the installation due to other priorities including attending Sun-N-Fun.
Fast shipping, well packaged parts and all paperwork included. Customer service was quick to get the right kit for me and get it sent. Couldn’t have been a better experience.
