		  I have an Odyssey PC545 battery. That battery uses 6MM screws to mount the positive and negative terminal to its brass lugs.



 There is only ~ .030" clearance between the bottom of the terminal and the battery case.



 I will be putting adhesive lined heat shrink on the terminal lapping onto the #4CC wire, but it will still leave plenty of metal exposed to create a momentary 1200 amp short, or at least 545 amps for 5 seconds. 



 Those silicone terminal covers don't have a chance to fit into a .030" gap.



 I could mutilate the silicone terminal covers, but it will not be a great fit but it will kinda work.



 I could put electrical tape covering the terminals, that will kinda work but a hack job.



 Anyone have any ideas for a more eloquent solution?



 See pictures #25 and #26:

  Why a battery box at all?  The RG batteries are quite

  happy strapped down in a simple tray. Capture the footprint

  in tray with say 1/2" tall sides and strap down with a

  couple of 200# plus webbing straps, either one of which

  would hold the battery in place with 10G acceleration.



  Alternatively, dishing the top of the box is the

  "legacy" approach. Our rules of thumb for clearances

  in the TC aircraft call for .25" min clearance for

  equipment items mounted RIGIDLY in the airframe

  and .50" is better.

Hi Bob



"Why a battery box at all?"



I agree, my "box" is missing the top half, and will be missing about 1/2

of the bottom.



Guess should have called it a battery tray.



You can see from picture that the terminals are completly exposed. I know

when working in the cramped quarters of the aft fuse, a wrench or

something metalic is going to short the battery, and besides branding me

with a red hot tool, the battery is going to shower me with AGM soaked

goo:

Ron,



Just a thought--why not construct a L shaped piece of lexan or other 

plastic. Screw one leg of the L to the top face of the battery hold down bar 

and use the other leg to create a shield covering the terminal.  It would 

not encapsulate the terminal but should keep an errant wench from making 

contact.  It would be an easy fiberglass lay-up; but I don't know if 

fiberglass is a conductor or not.  Others can chime in on that.
