Keeps my motorcycle alive and well!

LOVE this thing! I no longer have to worry if my motorcycle will start or not.

I permanently attached the leads on my battery so the small connector is tucked in my front grill. When I park my bike, I just plug the connector to the Battery Tender and it's all set. Takes me about 5 seconds. No problema!

Totally worth it.

THE BEST CHARGER/TENDER EVER!

I purchased a tender for my bike and liked it so well I bought two more. One for my brother-in-law and one for my sweetheart. The easy connect to the battery was wonderful, plus the quick clip for disconnecting from the charger is even better. It's a quality built item and I'm sure I'll have years of great service from it.
I'm really looking forward to giving the Tenders and watching the faces when they see how easy it is to install. My brother-in-law's battery is located under his seat, so he has to take the seat off and the battery out to recharge. So he'll really appreciate the easy connect and quick clip. I would definately recommend this item to anyone.

LOVE IT

This is a great product. I bought two, one for my brothers 2009 BMW R1200RT and one for my 2009 Harley Davidson Ultra Classic. I installed the harness on both bikes in just a few moments; it tucks neatly away under the frame. The quick connect is easy to close off with the include cap and easy to open back up. The leads are long enough and it charges well. I like the lights on the front that give me an instant view of the battery condition. Price is right too at about $24. I highly recommend this unit for anyone with a motorcycle.

Own Seven

I personally own seven and very satisfied. They are easy to use on any battery, snowmobile, 4 wheeler, car ect. and the best part is they do not over charge the battery.

Very nice product

This product has done everything it claims to do. My battery had gone dead over the colder winter months. This tender brought the battery back to charged level and is maintaining it until I can purchase a new battery.

Does the job!

Easy to use, easy to set up. The little green light indicates it's happy, too.
There's no way to know, of course, whether it made a difference since the alternative was to disconnect my '96 BMW M3's battery.
Don't bother with the cover. As noted elsewhere, the package it comes in is suitable for storage.

Just Bought My Second One

I bought my first Battery Tender for a BMW M3 that I drive infrequently because of travel. The car uses a lot of power even when turned off and idle. After having to replace a dead battery my dealer suggested that I purchase a charger to keep my battery in good shape. I believe BMW sells this unit under their logo, but I bought it from Amazon for much less $$$.

Problem solved! Even after a one month long business trip my car started immediately. Seeing that green light on the Battery Tender gives me peace of mind that my car will start when I need it and my battery will stay in good shape.


When my wife's Honda S2000 would not start after sitting in the garage for a few months, I thought I would try my Battery Tender before calling AAA. After an overnight charge the car started right up. After an additional 24 hours the green light was constant telling me the battery charger was in maintenance mode. My wife asked me to buy one for her.

One Note: find out if your car can charge via the cigarette lighter. This seems to be the most convenient method. BMW 3 series prior to 2007 can charge this way but newer models cannot. The Honda 2004 S2000 cannot charge via the auxilliary socket between the seats, so I installed the terminal set directly to the battery.

This device works, is solidly built, and is a good investment.

Deltran Battery Tender Plus fills the bill

I have a garaged car that only gets driven a couple of times of month at a weekend home. After about the 5th time of jump-starting a dead battery, a friendly neighbor/garage enthusiast informed me about "battery tenders." After reading the reviews here, I pulled the trigger on the Deltran Tender Plus, and am very happy. I hooked up the ring terminal harness in about 2 minutes and started the charge at around 8PM. Red light stayed on overnight, and by morning the green light was flashing and the red light was off, indicating an 80% charge. Getting to the steady green light with red light off(full charge and trickle maintenance) took another 6 hours or so.

Using this could not be easier, and it is tailor made for someone like me: garaged car over winter with sporadic use and night time temperatures in the 20s and 30s. My only quibble is that the ring terminal harness cord could be about 2 feet longer (it's only 1.5 feet) to allow the charge cord to be snaked through the car's front grill and capped when not in use. I did not use the included alligator clamp harness and will keep it as a backup. Because I have a power outlet in the front of my garage bay, I needed no other extensions on the power cord, or on the charging cord. I would guess that the fully extended outlet cord plus the DC charging cord, plus the DC ring terminal harness, extends about 12 feet total, so that should give you an idea of whether you will need any extensions (either power cord or DC cord) to reach your battery. I briefly considered buying the separate cigarette lighter adapter to charge, but because the lighter on my car is not "hot" when the car is off, it could not work.

For all of the technical reasons previously reviewed, I feel confident that the battery tender will now maintain a float on my lightly used car battery and there will be no more jumper cables in my future!

Must have if you own a classic car

All I can say is that it works great and I love the adapter that allows you to charge your battery without opening the hood each time. I use this on my 67 Caddy which I don't get to drive at all 6 months out of the year.

Battery Tenders

Battery tenders a a must for car collectors, auto enthusiasts, motor cycle lovers and really any form of transportation that requires a rechargeable battery. This product is especially useful when some vehicles are dormant for several seasons or are seldom used.

Auto batteries are expensive and the battert tender will significantly extend the life of batteries that are used only part of the time.

TO extend the reach of the trickle charger (Motorcycle - Lawn Mower)

I have a few pieces of equipment that often sit for month in the garage. So over the years I found it cheaper / easier to top off the batteries every month or so in the winter. As some equipment can take a few minutes to connect the trickle charger .. I got these to help make the job easier.

Would Buy Again. Good Price and Good Quality

Battery Tender Ring Terminal Harness

The Battery Tender Ring Terminal Harness is very handy for charging a battery that is not easily accessible. It allows you to install the ring terminal harness on the battery terminals once, and then just plug the extension cable into it when needing to charge or maintain the battery.

The length of the harness cable to the quick-disconnect feature is adequate for easy access when needing to plug into the battery charger without having to disassemble anything on the vehicle once it is installed. The dust cover provides protection to the quick-disconnect terminals and it keeps them from getting dirty, or wet when you are riding, driving, or boating.

The Ring Terminal Harness is a very handy item for being able to quickly connect or disconnect the battery charger.

Battery tender

If your tired of replacing your expensive ATV, motorcycle, or snowmobile batteries, this is the item for you. Plug 'em in and forget it. Maintains your batteries at full charge without overcharging. Extends battery life and, with the 2-pin quick disconnect, it takes 5 seconds to connect or disconnect. I have three battery tenders and alternate between three snowmobiles, three ATVs, and a garden tractor. They're a bargain online and way cheaper than replacing batteries.

Works great on the boat

I have two boat batteries with a combiner and a switch and use the battery tender to keep them both charged. So far it has worked as advertised and I would certainly buy it again or recommend it to a friend.

Permanent mount charger

Great charger when permanently mounted under the hood. I brought the plug out the grill and plug it in whenever the car is in the garage. Keeping a trickle charger connected will insure longest battery life.

Pretty good so far

I've only had this for about four months (I only rated it four stars because I don't know the long term quality). So far it works very well. There are other reviews that describe the unit. Please note it is only a two amp trickle charger and will not keep batteries that have serious drain.

Perfect for long-term battery maintenance. Must-have equipment for motorcycles.

As its name implies, this charger is designed for long-term maintenance charging, rather than recharging a dead battery in a few hours. Widely accepted as standard equipment for motorcycles that spend time sitting in the garage during cold winter months. Tops off the battery automatically and keeps it healthy. It's also worth getting just to have the adapter permanently mounted on the bike, as there are so many accessories made to work off battery power by plugging in to the battery tender adapter (for example, Slime's "Power Sport Tire Inflator," which is a great portable air compressor you can use anywhere with the battery tender adapter. Slime 40001 Power Sport Tire Inflator). The waterproof model is worth getting if you're going to leave it out to charge all the time (as recommended) to protect against moisture or any exposure to bad weather. I've used it to charge a dead car battery, too, and it worked but took about 18 hours.

Great product

Solid, works well, could not not ask for more in a battery tender. A must have item if you don't drive your car regularly. Cheers.
