Battery tender?

[hkreck]

I just got new coach batteries and am looking for a maintenance device. I had a battery tender jr on the old batteries but am not sure it was powerful enough for a two battery system. Any suggestion on this? maybe a battery tender plus or battery minder? Thanks

I run a battery tender junior on my diesel truck with two batteries and it does fine. It just takes a little longer to change from red to green (several hours) as compared to my gas truck with one battery also on a battery tender junior.

I have a harness with the plug on each battery and switch them every couple of weeks.

I think it's time for a new tender, had it on the batteries for a week and nothing happening. But the battery tender I have is about three years old so maybe that's the problem. Think I will go up to a battery tender plus this time.

I use one of these...actually, my second one as I ran over my first...

It actually puts out enough amperage to charge a slightly larger battery bank. The battery tenders didn't do the trick for me. Never would completely float them.

Well-reviewed and reasonably priced:

As my battery tenders died, I switched to the ones below. A little more money, but more functionality and current.
