Very Inexpensive Battery Maintenance Charger

1.0 ampere output. 13.8 volts regulated charge limit. This unit is good for 100 amp hours worth of batteries. IMO the voltage is a tad high for a high antimony RV battery with temps 60F or higher but an inline 3 amp shottky diode will fix that in a rush (13.5 volts).

This is a good, reliable far east company I've dealt with many times. No chicanery. They send items via China Post, no shipping charges.

This is a reliable completely inexpensive way to maintain a number of batteries stored for the winter. I would recommend substituting cheap auto parts store battery charger clips for the alligator clips.

Sorry. I just cannot afford half a dozen fifty dollar battery maintainers.

    The Deltran and other high dollar battery maintainers are excellent. IMHO it would be foolish to substitute a cheaper maintainer if the original was working fine. But I have a large number of batteries to maintain and at 50 dollars a whack I simply cannot afford the premier maintainers.

    I am gonna stick with my Deltran Maintainers.

    I been just plugging them in and forgetting about them during the winter for years.

    I know - hard headed, but it is not broke and I ain't gonna fix it.

    I have to admit that is a heck of a deal you found.

    "Somebody ELSE (or in addition) buy it"

    EDIT

    Mine works great. A better gizmo than the Harbor Fright transformer that is 20% LESS powerful.

    Someone buy it and let us know. I bought something very similar looking from HF, and it ended up going way up in voltage over time.

    I might add this is a switch mode charger that uses about 70 percent less wattage than the harbor fright style transformer type float charger to maintain a battery.

    The price is definitely right.

    I think I'll try a couple.

    Thanks for the info.
