Poor Reliability. They stop working after 12 - 18 months.

Reviewed in the United States on April 10, 2019

Size: 12V @ 0.75 AMPVerified Purchase

Does not Last long. Over the years I have purchased about 10 various size and voltage battery tenders. I have purchased 4 or 5 of these smaller 12v 750 mA chargers to keep our various motorcycles and UTV batteries charged at 2 different locations. They all work for about a year or maybe 18 months and then they simply die. The product is now cheaply made, and very light weight compared to the older ones that I purchased and are still working. Quality and reliability of these newer, lighter weight small chargers are very disappointing and I no longer recommend this brand. I have finally had enough of buying these chargers and will begin to ship them back to the manufacturer under warranty - what a hassle. Save yourself the aggravation of a failed unit that you have to ship back at your own cost and buy a different brand. Battery tender is not what it used to be! They give you a good warranty period but I would have to think that because you have to pay for shipping they are counting on people just disposing of them rather than retuning them. I would have to say that it has consistently been one of my worst purchases and I will stop buying this brand going forward.

Highly recommended!

Reviewed in the United States on November 1, 2016

Size: 12V @ 0.75 AMPVerified Purchase

Bought a pair of the Tender Jr. in 2012. I'm sure they have paid for themselves by maximizing the life of my expensive lead-acid batteries. There are plenty of reviews here proving that this is a quality product that has been around a long time. I wish to add that the company that makes Battery Tender products, Deltran, stands by their products. One of my "Juniors" recently stopped working after four years of continuous service. I emailed the company and received a prompt reply. I returned the unit and received a brand new replacement covered under their 5-year warranty. You can't go wrong with this product or company.

Edit: For those considering this product... It is not a battery charger. It is for maintaining fully charged batteries. There are some negative reviews from folks that did not realize what they were buying.

Bummed Out

Reviewed in the United States on November 4, 2017

Size: 12V @ 0.75 AMPVerified Purchase

I ordered 2 of the 021-0123 Battery Tender Juniors. They arrived on time, I unpacked one of the 2, hooked leads up to the car battery, plugged in the charger and watched the light as I made the final connection. Everything went as the manual said it would. I was waxing the car as the charger was doing it's thing and after about 15 minutes the charger started "clicking" and died. I unplugged it and waited a few minutes, plugged it back in, and nothing.
I unpacked the 2nd 021-0123 Battery Tender Junior, intended for my motorcycle, plugged it in and it lasted maybe 15 seconds and did the same "clicking" thing and died. The replacement process went smooth but I have not received the new ones yet.

These battery tenders are very cheap feeling compared to the old models.

This is a piece of junk. Lasted less then 2 months and quit working. I didn’t even use it very much, but plugged in in one day last week and nothing. If they are no better than this, and made in China anyway, I might as well buy the cheap ones from Harbor Freight. These are Battery Tender in name only, don’t waste your money.

VERY DISAPPOINTED - STEER CLEAR OF DELTRAN !!

Reviewed in the United States on July 22, 2020

Size: 12V @ 0.75 AMPVerified Purchase

DELTRAN Battery Tender, Jr 12volt, 750mA Automatic Charger. purchased from Amazon. VERY disappointed in this product, and this company. I purchased this product in Sept 2018 to keep a 14A-A2 quad battery topped off. It quit working mid June after only 21 months into a 60 month warranty. I tried to call Deltran several times and left a call back number, but no callback. Then I sent an email-same thing, no response. So I decided to look further online into warranty claims and discovered that they want you to send the failed unit back to them "on your dime", and, enclose a check for $8.95. So after 21 months, I now need to basically spend the equivalent of more than half the original purchase price. Some warranty! Out of principle I probably will just throw this piece of junk out and purchase from a different manufacturer. I bought this model because of the 5 year warranty, had I know how it worked I probably would have chosen something else. DO NOT buy from DELTRAN, they apparently don't care about their customers. More Made in China garbage!

Poor Product !

Reviewed in Canada on February 9, 2019

Size: 12V @ 0.75 AMPVerified Purchase

I have no idea who is leaving these great reviews but honestly the product is not good. I have been using these chargers for years, this brand is more expensive than most but they were always made in the USA so well worth it. Not anymore, the newest ones say made in China, and that alone is a huge problem. Tried this with several batteries and while it charges, very slowly it never enters float mode, so it's always charging - even when another charger will show it's full. After 24 hours and the battery overcharging already, we just disconnected it. Very poor product, clearly there is no longer any quality. Sorry you lost out on our business - all because of China.

One of the best car accessories I've ever purchased.

Reviewed in Canada on October 20, 2016

Size: 12V @ 0.75 AMPVerified Purchase

Great product. It's small, well thought-out and does what it says on the box.

I travel a lot for work, so my car is parked at home for 2-3 weeks every month. I drive a BMW, and the electronics draw the battery down while it's parked. It will start after 2 weeks but not after 3 if no one runs the engine. So I picked up a battery tender junior and I've been very happy with it. It's small enough to tuck in the trunk, and the detachable leads are a great feature - I leave them attached to my car's jumping posts under the hood, so it takes all of a few seconds to connect or disconnect.

It's kept my battery in great shape. In fact I've gained a few tenths of a volt both with and without the engine running, which is pretty fantastic considering my battery is 4 years old. I run a couple aftermarket amps, an obd2 wifi dongle, and a radar detector, which I know is taxing on my car's electrical device, so this guy gives me some peace of mind. And it's a steal for the price... it's a half to a third the price of a decent trickle charger, and it's better for my battery which is going to save me money over time. Very happy with this purchase.

Well worth the price

Reviewed in Canada on January 20, 2016

Size: 12V @ 0.75 AMPVerified Purchase

If you own an automobile, a lawn tractor, or even a generator that requires a 12 volt lead-acid battery to start and are stored for several months between use, then you owe it to yourself to get one of these. Just attach the (included) cable to the battery, and when you store the car/boat/ATV/etc for the winter, simply connect the wire and plug it in. The Battery Tender will maintain your battery without overcharging it, and use very little electrical power doing so. When it comes time to start that equipment in the spring, the battery will be fully charged. And since the Battery Tender does not overcharge or allow the battery to drop below a safe threshold, your battery will last longer as well. I've purchased three to date, and they were well worth the investment even at manufacturer's suggested retail, which is what I paid for the first one; Amazon's price is about half that, so I bought two more!
