Edit: For those considering this product... It is not a battery charger. It is for maintaining fully charged batteries. There are some negative reviews from folks that did not realize what they were buying.
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.
Accidentally killed a brand new car battery leaving a stereo hooked up in a car that sat for two weeks.
Drained that sucker down to 4 volts. :-0
Once a car battery is at 9v or lower, common knowledge is it has to be replaced. But sometimes newer batteries can be saved.
Apparently the key to saving a drained new battery is to trickle charge it back to life very slowly.
I let the tender charge it for a couple hours, unplugged it and finished charging the next day.
Battery took a full 13 volts and holds it well!
Yay battery saved!
If I would have jumped a battery that low it would have killed the battery and possibly the alternator.
Thing saved me like 80 bucks already.
Then I replaced a battery in another car, and found it wasn't quite charged all the way brand new.
Apparently even new batteries should be trickle charged before the first use to prolong the life.
Brought that one from 12.4 to 13.0 volts in a couple hours.
I haven't even got to it's intended use yet, which is to maintain a charged battery for long periods of time.
This could break tomorrow, and I'd still feel I've got my money's worth and buy another one.

I travel a lot for work, so my car is parked at home for 2-3 weeks every month. I drive a BMW, and the electronics draw the battery down while it's parked. It will start after 2 weeks but not after 3 if no one runs the engine. So I picked up a battery tender junior and I've been very happy with it. It's small enough to tuck in the trunk, and the detachable leads are a great feature - I leave them attached to my car's jumping posts under the hood, so it takes all of a few seconds to connect or disconnect.
It's kept my battery in great shape. In fact I've gained a few tenths of a volt both with and without the engine running, which is pretty fantastic considering my battery is 4 years old. I run a couple aftermarket amps, an obd2 wifi dongle, and a radar detector, which I know is taxing on my car's electrical device, so this guy gives me some peace of mind. And it's a steal for the price... it's a half to a third the price of a decent trickle charger, and it's better for my battery which is going to save me money over time. Very happy with this purchase.
