Installed 8, 6V GC2s from Sams Club in May 2009. We use 160 to 200 amp hours a day. Charged with
engine or
Honda 2000 until 12/12, when we installed 675 watts of
solar. We stored the boat for 5 months over that time period, otherwise we are full time cruisers. Usually run down to 70% at night, then charge up to 85 to 95 % during the day. Have never gone below 50%.
Batteries holding up great, as of today.
