Done Right By Me

Bought a Genius10 to restore an AGM battery that had been deep drained not once but twice within 3 weeks after Covid started and I stopped driving. Before purchase, even after a full charge overnight at Autozone my battery was dead again within 3 weeks, was afraid I'd have to purchase a new battery. But the Genius 10 did an excellent job of restoring it to full charge and able to hold a charge again. I've been using it since then without any problems (2 years) to keep my second car's battery healthy and charged since I don't get to drive it much anymore, this is after going through 2 other "battery minders" that died within 2-3 months.

Yes, I recommend this product.
