I've owned my Battery Tender for about 20 years, but I think it is starting to fail. Not sure what the problem is but I'm thinking its time to buy a new one. But unlike my current one, the new ones are made in China with all of the resulting risk of problems and failures, despite the warranty from Deltran. So looking into alternatives, I found the NOCO Genius. Its about the same price as the Battery Tender Junior and seems to have the same capabilities. I'm wondering if any of you have or know of this charger/maintainer and what your experience with it has been.
