Item Description

The Battery Tender Junior Charger is much more than a trickle charger. It is lightweight, compact, fully automatic and very easy to use especially in small spaces. The car trickle charger chargers offers ideal solution for keeping your vehicle batteries optimally powered when they are not in use. Whether it is a lead-acid battery, including standard and sealed AGM and GEL Cell battery types or any other kind, the 12v Automatic Battery Charger can be used to charge them all. It uses a 4-step charging program and is spark proof. The Battery Tender Junior Charger comes with a 12-foot output cord and allows for maximum optimization of battery power, without overcharging. The 12-volt battery charger is eco friendly and an excellent mean of ensuring that your battery is fully charged throughout.

Battery Tender Junior:
  • Perfect for all lead-acid, flooded or sealed maintenance-free batteries (AGM and gel cell)
  • Complete 4-step charging program (Initialization, Bulk Charge, Absorption Mode, Float Mode)
  • Automatically switches to float/maintenance voltage after fully charging the battery
  • If the battery voltage drops too far under load, full charger output power resumes
  • Solid state, 2-color LED indicates stage of charger
  • Spark-proof
  • Reverse polarity protected
  • 12' output cord
  • 5 year warranty

Customer Product Reviews

Rated 4.7 out of 5★ by 199reviewers.
Rated 5 out of 5★ by Battery tender junior has worked great on large and small batteries. Good price, lengthy warranty, would recommend for anyone needing to maintain a seldom used battery... just set it and forget it! 03/06/2012
Rated 5 out of 5★ by Battery Tender Jr. works great I have had three Battery Tender Jr. for years and they work great. For some reason, one quit working (approximately 10 years old) so I checked the Walmart web site and they had them on sale for an excellent price (at that time almost $10 less than the store price) so I jumped on ordering a new one. It only took one day until it was ready to be picked up at my local Walmart. 12/19/2013
Rated 5 out of 5★ by great deal from Walmart I've been using Deltran battery tenders for over 15 years now without a problem.I now have 3 and the original is still doing its job with continuous service. 08/14/2012
Rated 5 out of 5★ by This is a great product. Wish Walmart would stock some of these on the shelf. I purchased 4 of these and it was super easy to install them. This product is way easier than replacing batteries every spring. 11/19/2012
Rated 5 out of 5★ by Great for motorcycles over winter Had one prior to this that eventually wore-out. I ride my Harley all year long and winters are hard on batteries. I need to know that when the weather breaks, the bike will start. I also have one on my boat. 04/04/2013
Rated 5 out of 5★ by Great charger for RV'ers Arrived @ store on promised date, only had it 2 weeks but seems to be working as expected. 01/19/2012
Rated 5 out of 5★ by Exactly what I hoped for I needed the battery tender so I could keep my car battery charged up while the car is in storage during the winter. I wanted a device that would monitor the battery's condition and maintain the charge without "cooking" the battery. This device was simple to connect to the battery (I used the adapter that connects to the system through the cigarette lighter) and it worked through the appropriate cycles as soon as I plugged it in. Now I am confident that the car will start up immediately when I want to take it for a spin in the spring. 12/22/2013
Rated 5 out of 5★ by Excellent Charger Charger performs as advertised. Red light while charging, blinking green when almost charged, solid green when fully charged and on maintenance mode. Hardest part was taking it out of the plastic packaging. 03/06/2014
