I was one of the beta test sites for
the Surrette, lead calcium, L-16 style, wet cell battery starting in
2008. These are a part of an Outback grid-tied RE system. After the second year of operation today I checked and added water to the cells. The batteries used about 5 ml/cell over the last year, so basically nothing. Once again I feel the need to recommend this battery chemistry for grid tied with battery backup systems. The water consumption (as is typical for lead calcium batteries) is basically nothing. The float charge rate is also much less than standard lead antimony batteries. The expected life is much longer too. I have an old set I got from the local hydro plant I work at that were 20 years old at the time (the end of their "service life"). After 25 years they are still going strong. Todd -- Todd Cory
