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 203reviewers.
Rated 5 out of 5★ by Battery Tender Is The Best I have been using a Battery Tender many tears for my Harley-Davidson to keep the battery fully charged year around. I bought this Battery Tender Jr. for my John Deere tractor to keep the battery fully charged on a year around basis. Batteries last so much longer when they do not have a major swing in there charge.Great thing to have if you want to make sure you always have a full charge. Great for even storing your vehicle over the winter and not have to worry about a frozen battery or loosing all your electrical settings. 10/21/2011
Rated 5 out of 5★ by Great Product Line- Battery Tender I own three of the Battery Tender line of products. This one, to keep a back-up battery for my whole house generator ready for duty & two other units (a waterproof 800 & a Power Tender). The other two keep my RV chassis & coach batteries fresh when the RV is not in use. All the Battery tender units work great & keep the batteries in "like new" condition. 07/04/2011
Rated 4 out of 5★ by Easy to install/use Wish one part was better I found it very easy to install and I like the option of using the aligator clams or hard mount. The one part I wish was better is the cap for the 2-way connector. I have hard mounted it to my ATV so with the cap not staying on the connector will be exposed to the elements you encounter on an ATV.On a side note, I was shocked to discover the price on line compared to the price in my local store. I was pricing this item out at the store and took a cell phone picture of the price so I could compare it to other places. The price on the shelf was $34.97. As I was seaching the item on line the same item was priced at $23.00. I clicked on it and low and behold it was the Wal-mart sight. It said the retail price was $25.00 on sale for $23.00. So I orderted it on line and had it shipped to the same store I say the shelf price of $34.97. With in 2hrs it said my item was ready to be picked up, so I know the item was pulled off the shelf at the store for me and not shipped there. This does not sit to well with me because now before I purchase anything above $20.00 I am going to check the price on line and compare it to the in store price. I am also wondering how many other items I have over paid for over the years. 11/27/2013
Rated 5 out of 5★ by Great for their intended use. This does exactly what it is supposed to do, keep auto and deepcycle batteries fully charged without overcharging. If you have a dead battery, it will take forever (if at all) to charge it up.Its float charge is 13.05-13.08V, pretty consistent across the four chargers I own.I am able to keep two 115Ah batteries fully charged on one Tender Jr., but have to fully charge them with a standard charger then disconnect and immediately attach Jr.So, I have eight deepcycle batteries that the four Jr chargers are able to keep topped off. With a couple of 12V-110V 1500 watt power invertors I am able to run my furnace, refrigerator, tv and a few lights when the power goes out. I'm in Minnesota, today its -10, so power outages can cause some pretty severe problems fast. 12/07/2013
Rated 5 out of 5★ by Great product I now have four of the battery tender jr's bought the first one 2yrs ago I have it hooked up to my harley.I had back surgery 18months ago and am just now getting back in the saddle.The battery tender jr has kept my battery hot and ready to go.Was so impressed that I bought three more for my boat and ATV no jumper cables or battery chargers needed any longer! 02/19/2014
Rated 5 out of 5 Keeps Battery at Peak Level Outstanding! Drive a ZL1 Camaro with winter only tires so the car is kept in the garage for several months due to the cold New England weather. The Battery Tender Jr keeps the battery fully charged. Super easy to connect/disconnect, leave it on for months, automatically stops charging when not needed. Also great for motorcycle batteries. 12/23/2013
Rated 5 out of 5★ by Works like a charm on our RV Coach battery. After our new coach battery would not start the RV, we found out that even the newest battery will go dead if not used. We are fulltime in the RV while I am working and we rarely take the RV out for a ride. This device works great and had the battery fully charged in a day. I like the fact that it won't over charge the battery like others will do. 05/15/2012
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
