Customer concerns led Bogert Aviation to address corrosion problems found in aging Piper metal slope-top battery boxes. At the same time, the company provided a solution for aircraft with plastic style boxes that are prone to broken vent tubes, warped lids and cracking.
Bogert’s battery box, just awarded an STC from the FAA, is a bolt-in replacement for most Piper Cherokees regardless of original metal or plastic box installation. It is similar to Piper’s metal sloped top box, but with several improvements. Box construction is welded stainless steel with stainless steel drain tube instead of soldered seams and copper drain tube. Also, if a vent tube becomes damaged, the screw-in vent tube design allows for a quick and inexpensive change. Bogert also incorporated a previous STC, the battery box modification, into this box. The modification’s U-shaped nylon flanges offer extra protection against shorting, greater access to the battery and cleaner electrical connections resulting in reliable starting. Boxes are available in bare stainless steel finish, but the company suggests taking advantage of the powder coating. It is a few dollars more but will provide maximum resistance to corrosion.
