After I left both AGM batteries just sitting there for months, when I finally put them on the Noco Genius 2, they both read fail, something like internal short. I bought new ones. A fortnight ago I bought a Genius 2X2, so I could put them both on trickle charge together over winter, which I did about a week and a half ago. Checked them today, expecting to see internal short failures, but greeted with 2 solid green LEDs. Maybe I should buy that third bike so as I can use the other charger?
