[RE-wrenches] life expectancy of sealed batteries

[Nick Houser]

Todd----read with interest your posting to re-wrenches about lead calcium  
bateeries in float service. I too have experimented sucessfully with  
ex-phone company lead cals. Around here you can often buy them for $50  
apiece. I
fing they're particularly good in micro-hydro service where deep cycling  
is not really necessary. For your information I happen to know that  
Surrette has a lead calcium project in devleopment with SMA. Don't know how
"affordable" they will be, though. Nick Houser  Off Grid Services,  Powell  
River, British Columbia. P.S> could you  please post this for me? I can no  
longer post to this forum, for some reason. Thanks.
