Nuckolls, III) ________________________________ Message 1 _____________________________________ Time: 07:37:32 AM PST US From: "Andy Elliott" Subject: AeroElectric-List: 24V replacement batteries? I have a Concorde RG-24-15 battery in my IFR EAB aircraft. It is an SLA-AGM type battery. It was installed in 2012, and has been living in Arizona for the past 16 months. It is installed in the cabin, but experience has shown that batteries don=92t last too long out here, where hangar temps go over 120=B0F on a regular basis. 3-year replacement cycles are reasonable, and new from AS&S it is $549. Does anyone know of any appropriate service, perhaps non-aviation-specific, lower cost 24V batteries out there that could reasonably replace it? I have a little additional space to work with, so equal-size or smaller would be good! (It is approx. 5.95x7.11x7.15=94.)

Andy, Why not connect 2 Oddesey AGM batteries in series to obtain the 24v you are l ooking for? They are around $120-$130 each. The dimensions can be found onl ine but they are small batteries. You could also bend up a new battery box o r boxes. Justin > On Jun 6, 2016, at 06:34, Andy Elliott wrote: > > I have a Concorde RG-24-15 battery in my IFR EAB aircraft.

Even better, with an >*uninsulated* ring terminal for those two wires, >and stacking the terminals back to back you >might be able to keep everything in line Un insulated terminals will certainly reduce the cross-section of hardware . . . you can still insulated with double-wall heat-shrink per http://tinyurl.com/j6cueg2 Emacs! Also consider fabricating your own 'flag' terminals to be soldered on as described in Ch9 of the 'Connection. If you're really handy with the metal forming, you can make right and left hand flags that would stack back-to-back so that two offset fat wires in addition to a third, straight-on conductor could go onto the same terminal with the both offset wires on the same side. Consider 3/4" hard-copper couplers as raw material for the terminals . . . pick a drill bit for a mandrel that fits the proposed fat wires.
