Battery Tender Junior 12V Battery Charger is much more than a trickle charger. It has a brain, is lightweight, compact, fully automatic and very easy to use especially in small spaces. This battery charger will keep the battery fully charged so that it is ready to go always. It has a microprocessor controlled fully automatic charger and maintainer and is designed to extend the life of any lead acid battery commonly used in automobiles, motorcycles, ATVs, personal watercraft, RVs, boats, airplanes, golf carts, back-up generator systems, etc. Any vehicle or battery-operated piece of equipment not used on a daily or regular basis is a candidate for a Battery Tender charger. The advanced technology will bring the battery back to a full charge without overcharging and then float or maintain the battery for an indefinite period of time. The Battery Tender Junior comes equipped with alligator clips and ring terminals for easy hook up. An optional 25 feet extension cord (part number 081-0148-25) is sold separately. The Battery Tender Junior 12-volt/.75-amp battery charger is the small and simple solution to the challenge of keeping vehicle batteries optimally powered when not in use. It is able to charge any lead-acid battery, including standard and sealed AGM and GEL Cell battery types and is also designed to be easy to use in small spaces, to utilize a 4-step charging program and safely function in a fully automatic mode. Taken together this makes the Battery Tender Junior 12-volt charger an excellent means of ensuring that your battery is fully charged and ready to go when you are. .caption { font-family: Verdana, Helvetica neue, Arial, serif; font-size: 10px; font-weight: bold; font-style: italic; } ul.indent { list-style: inside disc; text-indent: -15px; } table.callout { font-family: verdana; font-size: 11px; line-height: 1. 3em; } td.vgoverview { height: 125px; background: #9DC4D8 url(http://images.amazon.com/images/G/01/electronics/detail-page/callout-bg.png) repeat-x; border-left: 1px solid #999999; border-right: 1px solid #999999; padding-left: 20px; padding-right: 20px; padding-bottom: 10px; width: 250px; font-family: verdana; font-size: 12px; } The Deltran Battery Tender Junior 12V Battery Charger with alligator clips, ring terminal, output cord

View larger. Safe, 4-step Battery Charging
The Battery Tender Junior 12-volt charger is much more than a trickle charger. It has a “brain”. Utilizing a 4-step charging program (initialization, bulk charge, absorption mode and float mode), it allows you to simply connect the charger to a battery, either in or out of a vehicle, and forget about it until you are ready to put the battery to work. Like all Battery Tender chargers, at the end of the regular charger cycle it automatically switches its output voltage to a safe, storage or float level that eliminates the need to worry about the damaging effects of overcharging, and the resulting need to check on the condition of the battery. If/when the battery voltage drops too far under load, output power resumes and the charging cycle begins again. The unit also features sparkproof connectors, short circuit and reverse polarity protection, an easy to understand charging status indicator consisting of a single LED, and almost no current draw from batteries connected to it. Key Features: 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 and 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 two color LED indicates stage of charger. Spark proof and reverse polarity protected. 12′ output cord. 5 year warranty. Charger Models Output Voltage Output Current Charging Software*/

However, for optimum battery performance in deep cycle applications (for example, running a trolling motor), it is best to chose the Deltran charger that has the charging software specifically designed for the battery type. Fortunately, since the technical staff at Deltran has developed charging software that works equally well for both STD & AGM batteries, the only choice to be made is between 2 models: either STD & AGM or GEL software.

The Tender Jr. Is Very Similar To The Tender Plus , Not Temperature Compensated, Less Amps! In the analysis of buying a Tender Jr. vs. a Tender Plus, the main issues are time to full charge, battery size, & parasitic draw. The Tender Plus (1.25) will get the job done twice as fast as the Tender Jr. (0.75). Both now are similar architecturally, save it be the charging power & lack of temperature compensation on the Jr. They both are 4 stage, both have the same sophisticated computer chip technology running the charging process, etc… I spoke to The Deltran(The Manufacturer)…

Warranty a Joke – BT Jr. Housing Melted Less Than 1 Year Old I bought my first Battery Tender Jr. about 20 years ago (for an antique car that I drove infrequently) and it worked fine for over 15 years. I included it with that antique car when I sold it, and as far as I know, it still works.Based on my prior experience, on November 4, 2010, I bought another Battery Tender Jr. from Amazon for another infrequently driven car. It is now less than 1 year later, and that Battery Tender Jr. got so hot that the plastic case buckled and separated at…

excellent gadget & easy to use The battery Tender Jr. comes with 1 set of permanent mount ring terminals & 1 set of mini jumper cable clamps so you can hardwire 1 car & use the clamps whereever they are needed.The 1-way quick disconnect on the cord makes things very easy to hook up & unhook. And it is maintaining my battery fine, no more dead car.
