Review on 🔋 NOCO Genius GENPRO10X2 Marine Charger - 2-Bank, 20-Amp (10-Amp Per Bank) Smart Battery Charger, 12V Onboard Battery Maintainer, Desulfator, and Temperature Compensation by Aaron Villanueva

I bought this charger to charge two 27 series AGM Duracell batteries on a sailboat. The batteries are only a week old and the charger says they are bad and shuts down. If you rely on your batteries to power your bilge pump off the boat, stay away from NOCO products. I tried to contact support with no response for 2 days. Plugged back in my old Promariner 5 amp and everything still charges fine, I was looking for a better charger and NOCO failed the test. Looks like I don't have $200 since I can't leave my boat without being sure the batteries stay charged. I am returning to ProMariner.
