HI Peter,
I don't know of any sealed that go above the 14.4v/12v setpoints.
And most I've seen a 14.2 ish.
That said I have seen eq recommendations for industrial sealed, but
with very controlled conditions.
above 14.4 it will start to gas just like a wet battery.

I have been told that AGM batteries can withstand pretty aggressive
charging rates, with a bulk rate being ½ of C/20. For example a MK
8A8D, with a C/20 of 245 A-h, would start with 122 A. If this is
okay, can I still use the standard 14.6 V value for switching from
Bulk to Absorb? What about ambient temperature effects at high
charge rates?
We have need from time to time to charge AGMs as quickly as we can
safely do so, so any information on high charge rates would be
appreciated.
