You may want slightly higher voltages than that. From what I've read, and
from working on a hybrid electric car with lead-acid batteries (granted, they were
SLA, not FLA), you can alegedly float them at 13.8 indefinately without damage. As
for an overnight, 14.0 probably won't give quite an equalization charge on the cells.
It may bubble a little bit, but 14.5 will probably help rejuvenate the cells more than
14... again, *only* for an overnight charge... not indefinately.
