Call Don Nieser at Commodore Aerospace. If he hasn’t got one, have a local fiberglass shop build you an owner-produced one using AC 23-27 as reference authority. Owner produced parts are not valid for Part 135 ops, though.
You could try using a box designed for experimental aircraft, use your AC 23-27 authority to have one "made" for you. A quick search brings up some nice custom-made battery boxes under $400, some closer to $200. Last edited by mshac : 09-25-20 at 11:22 AM. |

I’d argue that if you have a TSO sealed battery, you already have a battery box....under the above reference.

Yankee Clipper.
I have a serviceable battery box, no top, asking $400 plus shipping. If interested email me at bstory@pa.rr.com. BILLS pilot/owner/A&P PS: As quoted in this forum, I too replaced my (5 year old) battery with the sealed type, and it won't fit into the box, so I modified the hold down strap to secure the battery and all is fine. |

Not so, read this article. https://www.cessnaflyer.org/maintena...lications.html Last edited by Ed Coffman : 09-28-20 at 12:56 PM. |

Quote:
The air carrier has authorization to return to service a part (including fabricated parts) under the authority of their Certificate (and all the process controls that come with it). The typical Cessna GA owner doesn’t have that authority without AC 23-27. |

I still find it difficult to grok the regs, and the more I read about STCs and PMAs, the less I know. But if it helps anyone else, I think the following enables us to use a Concorde sealed type RG24-15M battery:
https://concordebattery.com/otherpdf/finalfaapma.pdf And how, oh fellow novices you ask, do we know this is a sealed type battery? We don't. But your (or at least my) IA does ... assuming it's even true. The Concorde site gives us a clue on its home page with mention of the RG series under that description. My assurance went pear- shaped when my IA seemed to suggest however that an RG24-16 was not. Now, another question (or two, or three) you might ask:
Well I intend to call them soon to get those answers. And thanks once again for the helpful replies that got me this far. I need now to work out what modification(s) I need to do to install such a boxless battery, and how to keep my IA out of trouble. He believes the original box provides some structural strength as installed, and that without it the bracket should be doubled with additional material. He's also not sure about the strap-down method, or what approval (i.e. paperwork, authorizations, etc) will be needed, if any. I'll follow up on this as well. |

Rg24-11m
The "M" means MOUNTED. "M" batteries are a direct replacement allowing the removal of the factory battery box. I've used them for years on other aircraft models. "M" batteries have a mounting system designed into them with a hole on each end, so the long bolts that originally secured the battery box are reused to secure the new battery, sans $1300 fiberglass box. Clearly the way to go if your fiberglass box is kaput.
From Concorde's description: "The RG24-15M features a manifold to facilitate direct replacement of the originally designed manifold vented battery" A picture: https://www.pilotshop.com/catalog/gr.../11-03877a.png Last edited by mshac : 10-04-20 at 10:57 AM. |
