Do you know if you need a battery minder? My plane sits in a hangar, but it's just as cold as outside. Fall/winter lows are in the 35˚-45˚ range. I've never used a battery minder. After four years my battery still showed about 24.5v when I arrived at the hangar and starts just fine.Mjwatlanta wrote: ↑Thu Nov 03, 2022 3:00 pmLike all on the thread, I want to install a batteryminder.
When stone cold the DA40NG starts in about 1s of cranking. If the temperature is down in the low 30's it will need 2-3s of glow plugs which won't kill the battery. This is very different than the Lycoming's which for a cold start need some priming and might crank for 5-10s.
Unless it's going to sit for an extended period, I doubt that you need a battery minder.
