Criticalcarecohen Posted January 21, 2023 Report Share Posted January 21, 2023 Hey Everyone, After a very long panel upgrade, an inflight emergency due to inappropriate rigging of the trim system after GFC500 install, the GFC SB which delayed delivery and a myriad of other issues..........N57FM, my screaming eagle is about to pounce back to the real world. During this time the number 2 battery "died" and I was told it wouldnt hold a charge. I was planning on replacing the battery at annual anyway as it would intermittently show low voltage (we were planning capacity tests and such per Concorde first). Anyway - I decided to replace both of my RG24-11M's since they are 7+ years old and hard to find. However, as I'm sure everyone who has needed a battery recently has noted - out of stock. I purchased the RG24-15 (non "M") and I'm aware that the non-M models are simply lacking the manifold vent plug from the old need to vent batteries, even though the -11M's were sealed and my understanding is they just include a little "dummy" plug to connect the battery vent into. So - Do we just plug the vent? Curious from those of you who have made the change to the non-M variants what, if anything, needs to be done. Happy to get flying again AC Quote Link to comment Share on other sites More sharing options...
LANCECASPER Posted January 21, 2023 Report Share Posted January 21, 2023 The RG24-15 is sealed and no need for a vent. Just pull the vent line and you can plug the hole on the belly. 1 Quote Link to comment Share on other sites More sharing options...

hypertech Posted January 22, 2023 Report Share Posted January 22, 2023 Is it actually a vent? I don’t think it is. There’s a circle there just so you have something to connect the tube too but I think it’s solid plastic. My vent lines are in a box on the shelf now.

With the attached rope, they’re actually easier to get in and out of the airplane. Just use the holddown bracket when mounting them and safety-wire the two wing nuts. Echoing @LANCECASPER’s and @amillet’s comments also about plugging the vent. Quote Link to comment Share on other sites More sharing options...
carusoam Posted January 22, 2023 Report Share Posted January 22, 2023 Oddly, the new batteries come with a top hold down plate with a place to connect the old vent/drain… no… the drain is definitely not a requirement for sealed batteries… And sealed batteries have good experience flying to high altitudes… How high do sealed batteries go? Any limitations? Great question since many Mooniacs fly in the flight levels… Go MS! best regards, -a- Quote Link to comment Share on other sites More sharing options...

M20R Posted January 28, 2023 Report Share Posted January 28, 2023 These batteries have gotten very expensive like everything else. Quote Link to comment Share on other sites More sharing options...

Look at the pricing for a Concorde battery in a Meridian or TBM and you’ll think these are cheap! Quote Link to comment Share on other sites More sharing options...

No doubt! I fly a Meridian for work and the new Concord 2 years ago cost more than the annual on my Mooney this year… and while I helped with inspection panel removal and installation, I paid a standard rate for the 30 hours of time I was charged.
