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

Rated 4.7 out of 5★ by 197reviewers.
Rated 5 out of 5★ by Great for charging and maintaining batteries My ATV battery went dead. My large battery charger would not charge it. I decided to buy the battery tender Jr. to make my batteries in all of my equipment that is only used once a week or less. I put the battery tender Jr. on the battery and after 3 days the battery was fully charged. I thought I would have to buy a new battery. I ordered the battery Tender Jr. online and had it delivered to the store. I will order more things from Walmart online. 07/20/2013
Rated 5 out of 5★ by This is all you need for your other car that will part in your garage under the cover most of the time. Easy to use, keeps your radio stations and clock up and the battery strong at all times. 03/04/2013
Rated 4 out of 5★ by Good item, not a great store So before I bought this online at walmart I went in store and bought it, got to the checkout and they charged me $37 dollars with the tax, I thought ok, I must have bought the better one not the junior tender. When I got home checked it out on line and it was exactly the same item so got online and purchased another one from my walmart and picked it up that day for $23 bucks. Tell me , How does that work?Anyway, good battery tender, bought a new battery for my bike that day and charged it up with the tender took a day and a half, fired up no problem and I use it every day now. 03/17/2014
Rated 5 out of 5★ by If It Holds Up It's An Incredible Deal! I've owned numerous battery chargers in the past and most, even famous brand named chargers, don't last long anymore.This is my first "maintainer". After reading up on this one all over the internet, I decided to take the plunge and the price at Walmart was the best anywhere.I have a 98 Dodge Grand Caravan with a 3.3 liter engine and it sits for long periods of time between use. It takes some juice to crank that thing and after sitting for weeks or more the battery in cold weather can drop to below crank level. I can always jump it but thought I'd try the Junior Charger. I'm happy to report that since using the Battery Tender Jr. I've not had to jump the van once. The van starts right up on first crank!I went ahead and used the battery clamp mount which has a non-shorting plug that sticks out of the grill at just the right place and length. When I need to use the van, I just unplug. When I drive back into the garage, I plug it back in, all without having to open the hood.So far, the device has worked perfectly and as the title implies, if it will last, it is an awesome deal. I also used the Site-To-Store option which took about a week, which was fine for me. 03/14/2014
Rated 5 out of 5★ by perfect option for a bike.. bought this after a friend recommended keep the battery on my motor cycle charged up and ready while parked through the winter in the garage..simply ideal..and just too easy to delivered/mailed it for less than $2. ... 10/31/2013
Rated 5 out of 5★ by We needed a trickle charger for a battery backup on our sump pump in the basement.The original one that came with the installation was a nightmare.This Battery Tender Junior is a pleasure and so far it is operating just fine. 11/29/2012
Rated 5 out of 5★ by Works as advertised Used the ship to store option when I purchased the battery tender. Battery tender came with everything needed to hook it up to the battery, although my motorcycle already had the pigtail connected. Plugged in the battery tender and walked away. Looking forward to a fully charged battery this spring when it is time to get the bike out of the garage. Very good product for the price. 11/25/2013
