Let me tell you, folks, the Battery Tender Battery Charger and Maintainer is like having a superhero for your battery-powered gadgets! It's the Batman of battery chargers - mysterious, effective, and always there when you need it. I bought this little gem after my car battery decided to take an unexpected vacation in the middle of nowhere. I mean, who doesn't love being stranded with a dead battery, right? Well, thanks to the Battery Tender, those days are gone! It's like a personal trainer for your battery, keeping it in tip-top shape. The setup was so easy, even my cat could do it. And he's more interested in chasing shadows than reading instruction manuals. The charger is so intuitive; I'm pretty sure it winked at me when I connected it right. Let's talk about speed. If this charger were a sprinter, it would give Usain Bolt a run for his money. It charges faster than I can decide what to have for dinner, and I'm notoriously indecisive! And the maintaining feature? Oh boy, it's like having a battery babysitter. It keeps my batteries healthy and full of life, like a fountain of youth. I half expect my car to start giving me life advice every time I turn it on. In conclusion, if you want to be the envy of all your gadget-owning friends, get yourself a Battery Tender Battery Charger and Maintainer. It's the best thing since sliced bread - if sliced bread could jump-start your car and keep your gadgets alive! Highly recommend for anyone who hates being stranded or loves their gadgets more than their morning coffee!

I have a few of these for MANY years. I think the oldest one is 25 years old. Still works great. Needed another one for my car since we're taking a longer trip and not using my car this time. Specifically looked for this model. Works great on keeping the battery up on BMWs which have weird charging software you have to reset when you change a battery. Wife's battery is going on 7 years now because it's kept on this charger during our long trips. Mine (same BMW model) died after 3 years because we're using my car for trips. Also have it on a rarely used sports car. It always starts right up and I've never replaced that battery in 10 years.

I have a 1967 Ford truck that can be quite a drain on the battery at times, especially during the colder months. I purchased this before last winter, and never once had an issue with the battery being too low or too cold, despite some pretty frigid temps. I set this on a shelf just in front of and above my truck, and leave the lead to the charger hanging. I then wired the battery end to my battery and channeled it so the plug end can be pulled through the grill. It's nearly invisible when it's not in use, but is very quick and easy to plug up. I've gotten used to just plugging up the truck every time I'm done with it, and this little puppy brings it up to full charge fairly quickly! Highly recommended, especially if you have an older car that either doesn't get driven much or is a heavy drain on the battery. ********************************************************************************** Update 01/02/11: Unfortunately, I sold my '67 truck back in the late summer of 2010. However, this little battery tender was still going strong, so I immediately hooked it up to my 4-wheeler. It has been doing a great job keeping the battery on it charged up through some especially cold weather we've had. So after @3years of use, I still give it 5-stars. Awesome product! Update 11/19/12: I noticed something really smelling in my garage, and spent quite a while trying to find it. It was a horrible "ozone" like smell, but clearly was the smell of burning electronics. When I got to my Battery Tender, I noticed the light was no longer on and it smelled really bad, so I immediately unplugged it. I'm not quite sure what happened, but am a little concerned about this. That said, I will consider replacing it as I still believe it's a good product. Update 02/19/13: As these units carry a 10-year limited warranty (if you have your receipt), I decided to send it in. The cost of mailing it was around $9 for standard post, and $11 for Priority Mail. The warranty replacement charge is $12.95 (why not just $13?). So in total, it will cost me just under $25. That is, assuming they replace it, which I certainly hope they will! I will post follow-up later. Update 03/20/13: It took approximately 2 weeks, but Deltran DID replace my charger under warranty. The thing is, the replacement charger - which appears to be brand new, and not refurbished - did not come with ANY paperwork. No "we're sorry for your inconvenience" letter, no receipt, no packing slip... nothing. So my warranty on the replacement will only be as good as the remainder of what I had left on my original 10 years (approx 4 years). The inconvenience of the return was frustrating, and I'd have liked at least an acknowledgement of that from Deltran, but it "is what it is". Hopefully this new one holds up at least as long as the first.
