I ordered 2 of the 021-0123 Battery Tender Juniors. They arrived on time, I unpacked one of the 2, hooked leads up to the car battery, plugged in the charger and watched the light as I made the final connection. Everything went as the manual said it would. I was waxing the car as the charger was doing it's thing and after about 15 minutes the charger started "clicking" and died. I unplugged it and waited a few minutes, plugged it back in, and nothing.
I unpacked the 2nd 021-0123 Battery Tender Junior, intended for my motorcycle, plugged it in and it lasted maybe 15 seconds and did the same "clicking" thing and died. The replacement process went smooth but I have not received the new ones yet.
