Battery Tender 021-0123 Battery Tender Junior 12V Battery Charger
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 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.
Great Product. I needed a way to keep my minivan battery topped off during extended idle time because my electronic rust protection device was draining the battery. This product does the job beautifully! The only trouble that I ran into initially was that the charger would not start charging because my battery voltage had dropped below 3 volts (this is a safety feature built into the unit). Once I got the voltage up above 3 volts (by briefly attaching jumper cables to another vehicle), it charged just fine. It took a few hours initially, but now I keep the battery connected while the vehicle sits in the garage.
