MC, It's really a matter of current, not voltage. Too much current will overheat the battery, warp plates, and possibly crack the sealed case. The rule of thumb is to charge batteries at 10% of its amp-hour rating. 14 volts should be the DC cutoff voltage while maintaining the 10% charging current, As the battery becomes charged, the current should be ramped down ending in a trickle charge of 100 to 200 ma to "float" the battery. I've seen many a battery ruined by a non limiting charger. Natch, the better chargers cost more, so do AGM batteries.
