Help ….. Battery preservation
 

There seems to be many choices out there for battery tenders.

What do you guys / girls use to keep your batteries “automatically” charged after setting for long periods of time.

I want something small that I can plug in and not worry about it.

I hear this unit below is ideal.

Opinions?

Thanks, Chris.

That's what I use. I added an extension for the charging cord so it reaches what I need in the garage and have the quick connect cords on each battery I charge. The 1st of each month I charge each battery and rotate from one to the other - each battery takes about 2 days to activate the blinking light for a full charge.

I use that one on all my cars and my Harley. Never an issue

Junior works for me also!

Bought one at Barrett-Jackson 2010. Still works great!

I had 17 batteries on Battery Tender Jr’s last winter, batteries are ready to go in the spring. I've had a couple fail over the years, but many of them are over 10 years old. The alligator clips get a little funky after a while, but you can buy a new set of clips and a cord for about $6 at Batteries Plus or Amazon.

Okay guys, I just purchased 3 Battery Tender junior.

I’m trusting in the above “tried and trued” recommendations.

Thank you for your time!

Just a heads up...The repo batteries that are really AGM inside of a old water filled looking case should not be trickle charged. If you want to charge it they want you to run it down with te headlights and then do a full charge.

I've had the 2 bank Battery Tender for at least 10 years. I have 6-8 batteries I store in a heated building every winter and keep them charged with it. I don't leave it on any one for an extended time. Once the green light goes solid, for storage mode, I leave it for 1 week and then move it to the next battery. Once they all have been charged, I stop charging for 6 weeks and let them rest. I have 4 NAPA Gold batteries that are 6-7 years old and still perform like new all summer.
I had to buy a new battery for my Harley this year. It is the second one since new and the bike is 21 years old. The original that came in the bike lasted 11 YEARS, most of them with this charger and the first replacement lived for 10 years. With a service life like that, I go right back to the dealer and pay the price for a new one.

This charger/maintainer works great on AGM batteries. It features an exercise mode that discharges and recharges AGM batteries. I have two Chevys with AGM batteries and use this Pro-Logix charger between them.
