I found the 1.25 amp unit would not charge some batteries. The unit just got damn hot. The company said it, "just stand by their products. I still have it and their smaller one.
Why do the units not charge some batteries?
I have owned several of these Battery Tenders over the years. I ordered this as a replacement for one that failed after many years. This one has worked well. It is not as sturdy as the original, but what is? I would likely purchase again, although would check out a few other units first to see if any seemed more sturdy in construction.
Battery Tender has kept my Optima batteries healthy for nearly 10 years. It keeps the batteries charged but not overcharged or overheated. I leave it plugged in all the time. The first unit lasted 8 years before it got fried in a power surge. Didn't hurt the batteries. This is the easiest way to keep your batteries healthy and ready to go.
I own several collector cars and daily drivers in two states. I use individual Battery Tenders with their plug-in harness on each car to make connecting/disconnecting simple and fast. I have used these for more than twenty years. They consistently extend the battery life, not to mention the piece of mind that comes with knowing your batteries are always fully charged and ready to go.
Over many years I have purchased four (now five) Battery Tenders for various charging and maintainer tasks. This includes the battery in a stored and occasionally driven 2005 Chrysler 300C, and a large 70 AMP generator purchased for the potential 2000 millennium power grid failure. Remember that fuss? Well, all of the tenders have functioned perfectly with only one failure after 21 years of continuous operation (the generator). Maintaining battery power to various dependent devices is crucial to immediate availability and longevity. The Chrysler fires up on the first turn of the key - every time; and it resides in a building with a F temperature variation of -20 to +115 degrees. It was good to find this product at Tire Rack. We have purchased tires and wheels from them several times over the years. They are the best. The service is unexcelled and their pricing competes with most any parts supplier. Just read the simple Battery Tender instructions and make the connection. You won't be sorry.
