I'm looking at the Battery Tender Jr. to keep my 2 twelve volt lead acid topped off. They set parallel. Can u comment on that particular one?

I'm not sure what else I could add. My choice has always been the BatteryMinder line because it pulses the battery to ensure sulfation doesn't ruin the battery. I don't remember seeing anything about the Battery Tender information making such a claim.

I keep one on my riding mower year around with great results. I know the battery is good when I open the shed and see it flashing - means the battery is fully charged and it's switched to float/maintenance mode.

I keep one on the chassis battery for my MH after I found out it would lose it's charge when plugged in. Only the alternator put something back in it. The inverter only keeps the house battery bank charged.

When I head out of town the day after Christmas, the batteries for my cars are all connected to BatteryMinders and are ready to go when I get back 3 months later. When I left them in the cars, they wouldn't even light the dome lights when I got back - even with a cheapo Harbor Freight solar panel plugged into the cigarette lighter - but they did get enough sun to warp the heck out of them.

Thanks again.....I've been finding mixed reviews about the Battery Tender Jr which I have already ordered. I'm going to try it on my coach batteries this winter. Many say it will "maintain" the charge on both batteries. That's what I want. Anything that will prolong the life of the batteries. The Interstates I had lasted under 3 years. Tired of that.
