RobertGary1 Posted October 9, 2019 Report Share Posted October 9, 2019 My Concorde was getting weak. My tester computed it at 100cca. So I put it on my regen for 48 hours and then afterwards charged it. Flew with it and then the plane sat for 2 weeks. On the next start it paused at the first compression but then spun like a top. Ever since it’s been working far better. So I’m not sure if it’s necessary to buy an Aviation regen system as the automotive seemed to work well. I’ll probably run a regen on it annually. -Robert 2 Quote Link to comment Share on other sites More sharing options...
RLCarter Posted October 9, 2019 Report Share Posted October 9, 2019 I agree, all I've ever used is a standard Schumacher battery charger and not a big fan of smart chargers either Quote Link to comment Share on other sites More sharing options...

Hank Posted October 9, 2019 Report Share Posted October 9, 2019 I'm on my third year with Concorde #2, still going strong (replaced #1 preemptively at six and a half years before flying into the hinterlands). All I've ever done is drop them in that black bix in the firewall and fly every niw and again--not near enough, and certainly not every week. YMMV, etc. Quote Link to comment Share on other sites More sharing options...
jetdriven Posted October 9, 2019 Report Share Posted October 9, 2019 the concorde manual shows how to do a capacity test, my first RG35AXC lasted 7 years. This one, 14 months. its 22% capacity. Quote Link to comment Share on other sites More sharing options...

RobertGary1 Posted October 9, 2019 Author Report Share Posted October 9, 2019 This is what I used. It something I keep around for boat batteries, motorcycle, etc. It seems to have done well with my Concorde too. https://www.amazon.com/gp/product/B01BYFSUJW/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1 -Robert 1 Quote Link to comment Share on other sites More sharing options...
lotsofgadgets Posted October 9, 2019 Report Share Posted October 9, 2019 Kitplanes magazine ran an article last year reviewing an inexpensive Harbor Freight charger. To quote the author "But when a $40 product1 from Harbor Freight saves me a $300 battery, it is worth writing about". I have used the same charger on my Concorde and on golf cart/rv batteries with good success https://www.kitplanes.com/aero-lectrics-66/ 1 Quote Link to comment Share on other sites More sharing options...
GeeBee Posted October 9, 2019 Report Share Posted October 9, 2019 You have to be careful with "Battery Reconditioning" modes. Some chargers use higher voltage to de-sulphate the battery plates. In AGM batteries high charge voltages can permanently damage the battery unless the voltage spikes are sent in pulses of 22-28 kHz. If your charger has an AGM mode and a reconditioning mode you are good to go, otherwise check the manual of the charger. Quote Link to comment Share on other sites More sharing options...
