[RE-wrenches] High to normal SG

[frenergy]

Jeremy,

             My response is welcome to the world of FLA batteries.  I 
see variations like this all the time.  Are you using a refractometer or 
hydrometer, are all the cells same manufacture date, are some cells 
warmer than others, terminal connections all clean?  I've tried 
"correcting" this from happening many times to no avail or marginal help 
despite longer absorb times or EQ-ing.  Some of the packs I maintain 
have different manufacture dates within the pack which I've assumed may 
have an affect.
