Now I can just leave the battery connected and fully charged all winter, and it's ready to go in spring. I highly recommend it!"

"I've relied on this charger to revive my car battery after long periods of inactivity, and it always gets the job done. The small size and lightweight build make it easy to mount and use, and the clips attach securely to my battery.

"I've used the NOCO Genius 10 to bring back a car battery I thought was dead, saving me at least $150-$200 on a replacement. After charging for four days, my car started perfectly even after sitting unused for two weeks.

I really appreciate that it’s fully automatic and features temperature compensation, which gives me confidence for long-term use. The compact design makes it a great solution for anyone with an auxiliary or relocated battery."

"This charger turned out to be smaller than I expected, which actually made installation much easier. The mounting system is clever and secure thanks to the snap-on back and Velcro strap. In my Silverado, I attached it above the front passenger tire well—the charging leads easily reach the battery. Even in cold weather, it keeps my battery fully charged, and I’m happy knowing I’ll be able to start my truck after it sits for weeks. I now have two NOCO chargers and trust them to condition and maintain all my batteries. Highly recommended."

"I bought this charger to keep my batteries maintained, and I’ve been very happy so far. The build quality feels solid, setup was a breeze, and the charging indicators are easy to read. Most importantly, it charges steadily without overheating, and my batteries hold their charge much better now. The smart-charging feature gives me peace of mind when leaving it connected. If I had to mention a drawback, I’d say the cables could be longer, but overall, this charger is excellent value and I’d recommend it to anyone looking for something dependable."

"Honestly, this was the best $35 I’ve spent. I grabbed it on sale just when I needed it most. My AGM battery was written off by three mechanics and several auto parts stores, but after using the repair mode for 6 hours, it read full. It’s super quiet too! I’m way less stressed now and no longer embarrassed about car trouble—this charger was a lifesaver for me."

"I needed something to see if I could revive my golf cart batteries enough for the built-in charger to work again. To my surprise, this charger did exactly that, identifying weak batteries and bringing them back to life, saving me hundreds of dollars.
