Can anyone recommend a good 24 volt battery maintainer?

I see tons of 12 volt battery maintainers out there, but not many 24 volt.

A maintainer stays connected to your battery 24/7/365 when the aircraft is not being used. They will extend the life of your battery, and help ensure your battery is ready to go when you pull your plane out for a flight.

Anybody using one they like?

“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.

We've been using the Schauer JAC2024H for 8+ years. It's available from Aircraft Spruce.
We've have no problems with it. It has a switch to select for charging for GEL or FLOODED batteries. You may need to buy an adapter or modify the connectors to suit your specific airplane.
