Every time I want to fire up my old 71 Datsun (that's Nissan for those of you younger than 30) 240 Z there's a good chance that the battery has drained down and that I can't start it! Looking around at car forums I read about this nifty little gadget....It's like a battery trickle charger....sort of. Whereas it's not recommended to keep a trickle charger hooked up all the time, this one has circuitry to limit the current and sense when the battery needs charging. It only charges at 1.25 amps which is easier on the battery.
I've had it on for a month now and it's great. The first couple of days, the red light was on indicating charging. Since then it's been on green and the car starts right up. I live in Houston where the heat and humidity can be just as brutal on batteries as the cold.
I highly recommend this "tender" for those that have cars that stay unused for long periods.
As other reviews have mentioned it comes with a set of adapters that allow you to permanently attach pigtails to the battery posts and then you can quickly connect the tender without having to use the alligator clips (also included).
For the price and free shipping you can't go wrong!

This little gizmo is dynamite.
I have a 4 year old Accord that, due to circumstance, only has about 4400 miles. Rarely driven...and what driving is done is mostly at night.
Sat for a week once in very cold weather...dead battery.
Ordered this. Hooked it up. 100% charge and the battery is very powerful once again.( had thought I would probably need a new one).
It's very small size makes it extremely easy to use and store. And it will not overcharge, so you do not have to babysit the process.
It's LEDs glow red when charging. Green and red blink once 80% has been achieved. Solid green at 100%.
It did, in very cold weather, take a long time to establish a full charge on my almost completely discharged battery. The battery would have been usable in a few hours, but 100% took close to 18.
Highly recommended.

I have an older version of this charger that I bought in the mid 90's. I used it to maintain my garaged Mustang's battery over the winter months for many years. I made a cigarette lighter adapter so all I needed to do was to plug it in instead of using the alligator clips. I have to say this thing is dead reliable! It always kept my battery in prime condition. I love it and recommend it highly.

I haven't used any other tender for a battery and this was my first purchase of this type of product. It was very simple to hook up and it included the wires to "pig-tail" the tender to my battery. That was great becasue I don't want to have to remove the seat and remove the battery cover every time that I use it. With the "pig-tails," you just hook them to your battery terminals and place the wire where you can run it down underneath the battery box and out the side of the bike. You then put the battery box cover back on and the seat back on and you never have to deal with them again. The wire comes out the side of the bike and I used a plastic cable tie around the frame to keep the wire in place. The wire has a rubber cap, so when you want to ride, you just unplug the wire and put the cap on. You're done. It worked great from the moment I plugged it in. I would have no reason to try any other brand of battery tender.

I use this to maintain a strong battery charge on a vehicle that rarely gets driven over the winter. I opted to use the quick connector leads so I didn't have to worry about propping the hood up to clear the red and black clamps on the battery terminals.
