I am planning on doing a battery swap as soon as I get my hands on my airplane. I currently have Gill G-242 installed in my aircraft and from Concorde's battery replacement guide (http://concordebattery.com/main_nicads.php), seems like they are recommending the RG24-12. However, folks here seem to recommend the RG24-15:
If you go by Concorde's suggestion for the M20K 24V, its the RG25-15 for the TSO one: http://concordebattery.com/aag3.php?id=2272
From comparing the two - RG24-12 is "premium" but RG24-15 is "platinum"
RG24-15: http://concordebattery.com/flyer.php?id=41
RG24-12: http://concordebattery.com/flyer.php?id=133
Few questions:
-15 lists 200 CCA, -12 lists none... eh?
Peak power and power rating are higher in the -15 vs the -12. How much does the difference in IPP and IPR make in terms of starting up?
Both the Gill and the Concorde are lead acid batteries. Although the Concorde one is sealed, is it possible to have acid free ones? G-242 does have an acid-free option. Or is the performance not worth going that route? Ref: https://www.aircraftspruce.com/catalog/elpages/gillg242.php?clickkey=43875
Cheers.
