Customer Reviews:

  • Reliable Battery Trickle Charger
    This is exact replica to the BMW "logo" trickle charger, except way cheaper. I used it to charge my dead battery ... it took about 20 hours but it works. This is designed to maintain a full charge if you do not use your car a lot. It works well. I hook the trickle charger on to my "weekend car" and forgot it. Two weeks later my Battery cranked a six cylinder 3.2 liter engine under a 20 degree Fahrenheit temperature immediately! All lead acid batteries do loose charge if not used. However, maintaining a full charge does not impact the longevity of a lead acid battery. Excellent choice for weekend drivers....more info
  • Detran Tender Plus( Definitely worth purchasing)
    This was a must purchase for me seeing I kept killing batteries every two to three years. I was told about Deltran buy friends of mine that swear by them. I did my research before i bought the product and Horsepower Tv recommended this product and gave wonderful reviews on it. Its definitely doing what it says and is a great product if you own vehicles that sit for long periods of time then you will need one of these. Easy to hook up and most people that are electronic savy like myself don't need to read the directions at all. Its pretty straight forward product right out the box. ...more info
  • Best Float Charger
    I was looking for a battery charger for a classic car I have in storage and my sand rail. Turns out, this is exactly what I should have. It is alot smaller than I thought it would be and works like a charm. I just charged a car battery that has been sitting dead for two years. Got 80% in just two days! With a 10yr warranty, this American made product reminds me that we can still produce quality. The cords are long, the box is small, and this little workhorse has really impressed me. Great price and Amazon's famous fast shipping made for another satisfying online shopping experience....more info
  • Battery Trickle Charger
    I purchased the Beltran Battery Charger about a month ago. So while my experience with the product is short I am very pleased. It was easy to install and easy to operate with the plug in cable which is a great idea compared to having to put the clamps on the terminals each time. What I did not buy but should have at the same time is the extra cable length extension but that is an issue based on the way my garage is set up. I would rate this a thumbs up and recommend it highly....more info
  • No problems so far
    This year circumstances allowed me to store my precious BMW (I didn't feel like spending the $$$ on a new set of winter tires, and a winter beater fell into my lap), and this little battery tender is keeping her alive through the cold & snowy season. So far, so good. I stop in once a month and start the car up and move it a few feet to prevent flat-spotting the tires, and it's obvious to me that the battery is being kept at full charge. Without the tender, I don't think that it would last 2 weeks.

    Hook up was simple, and the battery leads are long enough to allow me to just perch the unit on a small table next to the car. Depending on where you have your car stored, an extension cord may be necessary, as the power cord itself isn't all that long. Once you have the clamps in place, just plug it in, and you're set....more info
  • Deltran Battery Tender
    I own seven of these tenders, and have them on everything from lawn mowers and motorcycles to steet rods and motorhome. I haven't bought a battery in ten years, and the batteries are always up when I need them. They are never overcharged. These tenders have paid for themselves over and over again. Also, if one does happen to die, Deltran stands behind it's ten year warranty....more info
  • Easy to use, excellent customer service
    There are so many battery chargers to choose from. After much research, I decided to go with Deltran. But even then, Deltran offers many models, plus accessories. I called Deltran for help, without any expectation. The customer service rep was friendly and professional. She walked me through the selection, and explained what each accessory was designed for. With her help, I concluded that I did not need any accessory (except one extension cord, which I already have).

    The charger is very easy to use, compact and light weight. The cables are long enough to reach the battery easily. My car has been in storage for a while, yet the charge time is rather short. I am happy. With a 10-year warranty, I feel assured....more info
  • Easy to use
    The Battery Tender Plus is very compact and easy to use. The terminal lug quick connect cable is convenient allowing the unit to be connected and disconnected in a second - a great feature when you use or move the vehicle. The only downside is that the cabling from the battery to the charger could be a bit longer. ...more info
  • Very Happy
    After having used the Deltran SuperSmart Battery Tender for about a month now, I can say I am very pleased with the Tender. I have alternated the Tender between two motorcycles and have found both motorcycle batteries to be fully charged at all times. I plan on using the Tender on my pickup during the summer months when I will be riding a motorcycle most of the time. I will not worry about having to charge the battery on the truck every now and then. I highly recommend this product...more info

    Deltran SuperSmart Battery Tender Plus 12-Volt 1.25 AMP Battery Charger

    This product is working as advertised. I have it connected to (2) batteries in my boat that is in storage. Last year I had to replace both of these batteries because I did not use a Battery tender over the winter. I expect this inexpensive device to extend the life of these (2) very expensive batteries....more info
  • Best Choice for Battery Tenders
    Purchased this product after having "problems" with other chargers. The charger really works great, I allow it "float charge" my batteries without hesitation, I've determined it works great.

    (It's displayed for sale at retail in very reputable recreational vechicle dealerships where I do business (@ way higher prices!). It's the only product they display, it seems to be the best choice for most customers.

    The cord(s) w/plug in disconnect is plently long, but I also purchased and recommend the 25 ft. accessory cord. Apparently, the "resistance" added by the additional wire length isn't a performance problem.

    It's a great float charger.

  • Battery tender
    We have a Volvo convertible that only goes on the road when we can put the top down. So we often had a dead car in the garage. I bought the battery tender for my husband for Christmas. The car had been dead in the garage for over a week. He hooked up the tender, let it charge over night, and the car started right up. The unit is small, the green light is easily visible. So far so good....more info
  • Battery Minder
    Love the battery minder. I have had a charger and used it for many years to keep my Travel Trailer battery charged through the winter. I would always leave it on forever as I would forget and it would overcharge or I would forget to put it on the charger. With the battery minder I connect it snd don't have to worry about it all winter....more info
  • Does what it sats
    It is the best product of it's kind that I have found. It is solidly built anf includes a 10 year warranty and all the connectors needed. I have one for each motorcycle and they just work. It couldn't be easier unless they hooked themselves up when I pull in the garage. ...more info
  • Battery Tender Plus a Great Product
    I have used several Battery Tenders to keep seldom used battery started vehicles ready to go and to protect the batteries. This product is the current upgrade of my previous models. Great product. Oldest unit is over ten years old and it still works great. Easily installed and used....more info
  • Motorcycle and More
    This was purchased for my motorcycle but decided to spend a few extra dollars to get the battery charger hook up too. The harness stays on my bike so I can have it tended whenever parked but can disconnect from the harness and connect the gator clips (battery charger) for other batteries that may need attention. Easy to use, great product for the multi user....more info
  • Deltran SuperSmart Battery Tender Plus 12-Volt 1.25 AMP Battery Charger
    Deltran SuperSmart Battery Tender Plus 12-Volt 1.25 AMP Battery Charger

    This battery tender is great. Not only will it keep your car or motorcycle batteries from sulfating, they will always be fully charged and ready to go with no worries about overcharging. Theoretically,a vehicle battery can last practically forever if it is properly maintained and doesn't sulfate. Using a "smart" charger is the only way to do this. I have two, a .75 amp unit for my Harley and the 1.25 amp unit for my 2 cars and I "top off" the batteries weekly on all of my vehicles. The bike stays plugged in all winter while it's in storage and it never fails to fire up immediately in the spring just like I had been riding it all Winter. I'll be using battery tenders on all my future vehicles for the rest of my life, that's for sure. ...more info
  • Better Than Advertised
    I usually only write a product review to share unfavorable information that I wish I had known about before buying a particular item. In this case I would simply like to extend kudos for a really fine product. If you want a very fine battery charger at an expensive price you need look no further. ...more info
  • Perfect for RV/Marine battery
    I purchased the Deltran SuperSmart Battery Tender Plus 12-Volt 1.25 AMP Battery Charger to charge and maintain two batteries. One for my pop-up and one for the trollign moter on my boat. The product is a four step charger with a flaot charge for maintaining the battery. It has worked perfect for my needs and at a much better price than other chargers.

  • Deltran SuperSmart Battery Tender
    I am very pleased with the Deltran Super Smart Battery Tender. The only negative is that it was 4 dayes late of the expected delivery date.

    I purchased it to charge my 20KW emergency generator because the installed charger in the 200 Amp transfer switch did not maintain the Interstate battery for more than a week. I had an authorized Guardian technican test the installed charger and it is defective and will replace it. After that I will have the Deltran for emergencies.

    It did a great job standing in....more info
  • Deltran Battery Charger
    I bought this charger for ATVs and Motorcycles. It works great, and is made much better than the cheap Wal-Mart battery charger. The permanent plug attachment for the battery is long enough to easily connect to the charger without removing the seat on my ATV. Amazon's price was cheaper than buying it directly from the manufacturer....more info
  • Battery Tender Plus 12-Volt 1.25 AMP Battery Charger
    This is a great product. Your battery will always be fully charged and ready to go. Also you won't have to buy a new battery every spring after the cold winter temperatures and lack of use zap it. It really pays for itself. ...more info
  • The Best
    This is a compact charger that does everything it's suppose to do and more. I would highly recommend it!...more info
  • Need a "spark" in your life?
    I did! (Need a "spark", that is.) My riding mower sits all alone in the cold, dark garage all winter and when it's time for that first spring mow...the battery is always dead! Not any more...hooked on this little charger and in a couple of hours I was in the seat bouncing merrily along mowing like mad. I'm as dumb as dumb about anything electrical, but this was a snap to use with easy instructions...I did a lot of research and came up with a WINNER!...more info
