Review on 🔌 Battery Tender Junior Charger, Model 021-0123 by Carlos King

I have ordered 2 021-0123 Battery Tender Juniors. They arrived on time, I unpacked one of the 2, connected the cables to the car battery, plugged in the charger and watched the light while making the final connection. Everything went as described in the instructions. I waxed the car while the charger was doing its job and after about 15 minutes the charger started "clicking" and died. I unplugged it, waited a few minutes, plugged it back in and nothing. I unpacked the 2nd 021-0123 Battery Tender Junior that was meant for my bike, plugged it in and it ran for maybe 15 seconds, made the same "click" and died. The exchange went smoothly, but I haven't received the new ones yet.
