Bogert Aviation received FAA approval for stainless steel battery boxes that will replace PLASTIC, ALUMINUM and STAINLESS STEEL battery boxes in most Cessna and Piper aircraft, providing critically needed replacement battery boxes for these aging aircraft. Acid leaking from corroded or cracked battery boxes is a safety hazard and can cause expensive structural damage. Bogert Aviation boxes feature welded stainless steel construction, threaded drain and vent fittings, positive battery box venting and nylon insulators.
