Assuming it is like any typical lead acid battery charging
voltage of a six cell lead-acid battery, to fully charge the
battery,  is over 13.8 volts.
It has to under 14.7 volts to prevent excessive gassing,
14.4 volts is generally the gassing threshold.

Most of the stuff here that includes a voltage chart at the
end, although geared for cars and drag racing, is applicable
to most lead-acid batteries:
