Why do you limit your selection to sealed batteries? I highly recommend Surrettes FC-420. These are flooded, lead calcium batteries in a L-16 case. In the last 12 months my home system's set has not used any noticable amount of electrolyte. Rated for 15 years, and should easily last 20+, IMO this is the best battery out there for grid tied with battery backup systems.

Any other brands i should be looking at in the sealed battery category for a fairly large Ah battery bank? 100 thanks ! -- Sunny Regards, Kirpal Khalsa NABCEP Certified Solar PV Installer Renewable Energy Systems [http://www.oregonsolarworks.com] www.oregonsolarworks.com 541-218-0201 m 541-592-3958 o
