Works well, and it's easy to use. I've used it to keep the battery topped up on my Civic Sedan which is only used for very short occasional trips. I would recommend this product.

It worked fine until today, sudden stop, no heat, no smille, no light, no sound. I have to contact the maker now !!!!

I bought this to trickle charge my AGM car battery because...well...I like the bass (I knew I had enough bass only when my wife called it childish - yeah, I’m that guy). Use of my amp at high volume can drain the battery and stress the alternator. I bought this particular brand/model after doing my homework. This thing is PERFECT (a term I don’t use loosely) for a trickle charger. First things first, the packaging is amazing - almost excessive! How often do you see that these days?? Nice heavy tin box to use for storage. I love, LOVE the adapter to wire onto my battery and ground. Basically attach the adapter to your positive terminal and your chassis grounding (do not ground this from the battery, it’s a fire risk - just follow the negative wire off the battery to where it bolts to your car). Attach the negative eye there and you are ready to charge. I used a few zip ties to keep the extra wiring from moving around - now I just park in the garage, turn off the engine, pop the hood and plug the Battery Tender right into the adapter. I can sleep tight knowing this thing is safely charging my battery. By the next morning, it’s a solid green light (indicating a full charge) and I just unplug it from the adapter in my car, put the rubber cap back on the adapter (nice touch, btw), and tuck it down between the battery and the box that surrounds it (ymmv). The adapter sits safely and works perfectly next time I need a charge after I drove by you pounding my bass so hard it rattled YOUR windows (you’re welcome). I appreciate that it came with a set of alligator clips to use instead of bolting it on your car if that’s easier for you or if you are charging up someone else’s battery. It’s idiot proof, it works as promised, it’s safe, and it’s a quality product. If you need a trickle charger, buy this - you won’t be disappointed. And for those of you wondering if you have to remove the battery from the car to charge it, the answer is no. Simply attach the adapter per the directions and charge away while the battery is connected and the engine is off. Good to go by morning so I can pound bass all the way to and from work - annoying everyone around me.

Purchased this product for my truck while I was deployed from my homeport of Guam. Used on a 2010 Silverado 2500HD...standard truck battery. Truck was in a carport completely shaded on the front end of truck. Used for 4 months while in the Guam heat, no issues. Then, used again for 11 months 1 week straight....truck crank on first try when I returned home....no issues whatsoever. And no one cranked for me while I was away. So this was true 11 month test in the Guam heat. I also have a smaller battery tender I just used as well on my battery for my 1973 Corvette that was in storage. I removed the battery, placed in a garage with battery tender on battery for 3 straight years. When I returned 3 years later, placed the battery back into my Vette, and voula....cranked first try!~ I am a huge Battery Tender fan. Been using them for over ten years, but these last three years have been a true test against heat in Guam, and long term storage of a battery. Both scenarios were a 5 star result. HooYah!~
