Can anyone recommend a good 24 volt battery maintainer?

“Battery Minder” 24 volt. Love it!

This one? https://www.amazon.com/dp/B01ERZ0CC4...language=en_US

Funny it says "aviation calibrated" right on the unit, but in the description it says "Not for aviation use" - WTF????

I’ve been using mine for 9 years now. I’m almost certain mine was for “aviation use” and specifically the Gill brand battery that I’ve been using forever. I’ve had good service with them so never felt the need to change…😊

We used the battery minder for concord batteries

I use a simple and inexpensive 24v power supply.

I like it! What settings do you use for maintenance mode?

I have a flooded cell battery.

However on my 182 have AGM battery and the $9 harbor freight job has maintained it for years without problem. To say, I have my doubts about these “aviation specific “ maintainers.
