What can I say, the BatteryTender is small, works well and is easy to use.
The best of the lot
I've tried a few other batterychargers/maintainers and this one is by far the best of the lot. I use mine with the optional cigarette lighter adapter and it works like a charm. My car's battery was completely dead and this baby brought it back to life in less than 24 hours. Now I just plug it in and leave it with no concerns about overcharging or damage to the battery. Great product.
I have had this charger for just over a month and have to say it does what it's suppose to do, Charge batteries unattended. I have not left it on for more than a day so I can't say how it will perform over the winter. I have four batteries that I will be charging all winter so I will be switching the charger to each battery not leaving it on just one all the time. Not sure if I really needed this more expensive one but I am happy so far.
I use a lot of these and they have never failed me.
I operate a professional Home Watch Service and Private Home Management group ([...]) and use these chargers for all my clients vehicles while they are gone for months at a time. They have proven themselves every time. Excellent investment. Mark, theHomeWatchGuy, author of "Leaving Your Home-ALONE"
I bought this to keep the battery on my pop up trailer charged. My battery was pretty well
charged the first time I used it and was totally charged in less than a day. I inadvertently left
the fridge on battery mode, and when I noticed it after getting home from a 3 day camping
trip, it was completely drained. Even the little warning light inside which takes very
little power was out. I was afraid the battery tender may not be up to the task, but I plugged
in in anyway, and lo and behold, it was completely charged in 4 days. I am very happy with
this investment. It is light and very portable and highly recommend.
