Battery Tender 021-0123 Junior Jr Battery Charger/Maintainer 12V @ 0.75A

The Battery Tender Junior is much more than a trickle charger. It has a brain. It's lightweight, compact, and fully automatic; very easy to use, especially in small spaces. It will keep your battery fully charged so that it is ready to go when you are!

Possible longevity issues By
Been using 3 or 4 tender juniors for quite a few years. Actually could use a fifth one. However, lately instead of charge light staying green some have fluctuated between green and red. Condition follows tender no matter if switched to other batteries. Other units continue to work fine regardless of what machine connected to. Will see what Deltrab has to say

I have used BT Jr for more than 14 years and if you ever use one you'll like knowing that your battery will be good to go every time you are.

Longevity? By
I have a Battery Tender Junior and have had it for about one and a half years.I used it to keep a small 12v 7A battery charged and ready.  Several days ago, I started getting an Error on my attached system of 'Lo Input Voltage' so I checked the output of the Junior and it was reading zero volts and the indicator light was just flickering.  It has worked good up to that point but it looks like the longevity of the Tender is not real good..

I have 2 of the Battery Tender Jr. with 0.75 amp output. One on a Backhoe with a very large industrial battery that is now over 10 years old and still going. The other goes on my Cadillac for the Winter. Great product. Thank You Deltran.

You'll want more than just one! By
I have 2 Battery Tender, Jr's in my garage. One for my Harley and the other for my Polaris ATV. If I still had a lawn tractor, I'd have 3 of them! The comfort in knowing that the batteries are being maintained in each of my stored vehicles is worth the price.
The units are simply plugged into the charging harness, wired to each vehicle, and forgotten until Spring. A green LED on the charger let's me know, at a glance, that it is doing it's job.
Just think, no more dead batteries in the Spring!
