14.4V is the normal charging voltage for a 12V lead-acid battery. It's a
0.2V/cell differential, which is what's needed to initiate charging
(i.e., to drive the reaction between the lead and the sulfuric acid.)

The warnings that are stamped into the plastic of the battery cases
themselves say not to exceed 14.6V, which makes sense - gassing AGMs
would be a bad idea. 14.4V is well within the safety margin, and
overcharging is the opposite of the issue that I'm having.
