For ease of use, The Deltran Battery Tender is an excellent way to charge and maintain the battery on your motorcycle, snowmobile, or even a heavy- duty vibrator, not that I would know anything about that! The kit includes a BMW type plug for machines so equipped, and an SAE adaptor with alligator clips. You can also wire the SAE adaptor right to your bike’s battery and have easy access to the plug- in. The battery is maintained in a peak state of charge, with no worries of over charging.

…or anything with a 12V battery that isn’t driven regularly. I’ve been using Battery Tenders for years on my motorcycle and airplane-both of which are usually battery-a-year propositions. I now have one for every vehicle but my daily drivers-even my hydraulic dump trailer. It’s simple to use:clip on the battery leads, plug it in, and forget about it. You don’t worry about a dead battery when you need the vehicle, and you don’t have to worry about overcharging, either. If it saves one battery from seasonal replacement, you’ve paid for the unit a couple of times over. Money well spent.

This unit is a workhorse for the money. I use it on my Corvette in the winter and in the summer I have my snowblower attached to the battery tender. This product is compact in size and simple to use. It came with different adapters that enabled use with different battery charging requirements.
I recently gifted a unit to my father in-law who leaves 2 cars in Florida year round.
A must have for anyone who has a vechicle or seasonal piece of equipment.

If you have a vehicle that you don’t use very often, use the Battery Tender to keep the battery charged. It slow-charges your battery, then maintains the charge. It works great!

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.

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!
UPDATE after two years of use.
I can now reconfirm that these battery tenders work great – I’ve had them hooked up continuously on two cars that stay in the garage a lot and I’ve NEVER had them not start right up. A quick glance at the LED display lets me know that the batteries are either charging or fully charged. It’s a real pleasure to be able to go right up and enjoy your wheels without having to worry about whether the battery is dead. I can’t say for sure, but I suspect that it lengthens the life of the battery as well.

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.

Most people labor under the misconception that periodically driving their car will keep their battery charged. Unless you are regularly putting up hours on the highway this isn’t the case. Average around the town driving doesn’t run the alternator enough to charge up the battery fully. This situation is exacerbated if you run the battery down for some reason (like leaving a light on or running the battery while parked with the engine off). When a battery is used for any length of time with less than 75% charge, sulfation begins to take place. Sulfation is where the sulfur in the sulfuric acid which acts as an electrolyte in the battery bonds to the plates permanently, reducing the battery’s ability to be recharged and basically killing your battery. There’s an easy solution – buy a decent battery charger and be sure to top up your battery’s charge any time you run it down – or periodically regularly for any car that doesn’t enjoy long trips where the alternator gets to charge the battery for hours at a time.
There isn’t a better charger around for the price than the Deltran SuperSmart Battery Tender plus. It’s the granddaddy – and it does the job quickly and well for a very good price. It has two indicator LEDs which show 4 status states (Verifying the battery, charging, charging with battery level over 80%, and fully charged – on trickle charge mode). This makes it easy to see what the charger is doing and when your battery is ready to roll. The Deltran SuperSmart is has a robust powder coat painted metal body and a modular plug attachment that allow you to hook up various battery connectors. It comes with two connectors (clips for car and marine batteries and rings for motorcycles).
While a battery charger cannot bring back a battery that has fully sulfated, a good one like this definitely can reverse partial sulfating. It’s better to prevent sulfating in the first place – and regular use (i.e. quarterly and after each significant battery run down event) will keep your battery in good shape for as long as possible. It’s like dental floss for your car’s electrical system.
