My go to maintainer is by Battery Minder (NOT Battery Tender).
I have 5x running 24/7 - two 24v units on a 48v 220A-H boom lift, 1x on
shack backup 12v 220A-H, 1x 12v on a dump trailer 120A-H and 1x on a
fork lift starter battery 90A-H. The higher capacity batteries use the
2 amp or larger maintainers and the smaller batteries the wall wart model.
No RFI noticed on any band.
These are great pulsed maintainer units. They de-sulfate amazingly well
and don't electrolyze the water away very rapidly. Been using them for
18 years after bad experiences with junk constant current/voltage
maintainers.
Again, NOT Battery Tender, these have not been reliable for me. Great
ratings on Amazon btw.

Hi,
I found a bad battery charger at my neighbors house and would like to replace
it with a better one. He will be mostly using it for charging his RAM truck,
which has 2 truck batteries in parallel all winter (big diesel). Also would be
good to use it for charging other dead batteries around the house...
I am looking at these two. Has anyone experience with these or others or
recommendations?
