Better when useing the battery clip's directly to the battery! work's fine.With plug in to wire's on auxillary unit of motorcycle.Start's out with solid green light THEN-Red light was constantly blinking.I gave up.Still useing my old unit.That say's my battery is fully charged.I feel it's a waste.On my wallet.Because my old battery tender even charged my car in March for 4 hrs. Of this yr.
***Note From BatteryStuff.com***
The red light flashing indicates that the battery charger has AC power available and that the microprocessor is functioning properly. If the red light continues to flash, then either the battery voltage is too low (less than 3 volts) or the output connector is not connected correctly. Some SAE accessories are reversed polarity from Battery Tender products. Since it works with the alligator clips directly to the battery I would suggest testing you polarity of the Auxilary connector as it might not be compatible with the Battery Tender products.

great
works Great.... I have a Battery Tender Junior 12V 750 amp mA and I also have a Battery Tender Junior 12V 800 amp mA. I use the 800 amp on my motorcycle and my 750 amp tender on my lawn mower. I'm wondering if either of the 2 can be used on either of the 2 batteries without making a difference to either application. Thank You L J

Works better than I expected.
Arrived in two days. My old NightHawk runs better now that its battery is fully charged before riding. The instructions are complete. Steps of operation are explained. I used it to top off a new Prius 12 V battery over night before installation. Mileage jumped.
