I got a 6/2 amp 12v charger from Kragen auto supply for cheap. I charged a
couple of Hawker 26ah ep with it and it seems to work well. I monitored the
charging though & to my shock it seems to be doing a flooded equalizing
charge. I guess I shouldn't be suprised. It charges at around 15.5vdc give
or take and then drops down to 13.28 and repeats till charged. It has a
handy green light to let you know you are done. The battery I was watching
started at about 12.7vdc. Is 15.5 too much for these Hawkers? I'd maybe go
15v Lawrence Rhodes......

I'd say yes, that's too high to go on a regular basis.

This is an example of the common "blinking-light" type chargers that never shuts off, but keep cycling between charge/float forever. The problem is not that it goes to 15.5v -- it's that there is no limit on how much time it spends there, or how often it does it.

As I monitored the charger it did seem to have a distinct time it remained
on High so to speak. (about two minutes) However as it stayed at 13.28volts
for a while, when the battery dropped below this voltage it always popped up
to 15.5 again. The time between jumping up though does get longer as the
battery stays on float. Since the float rate is 13.5 this might be ok. But
I'm not convinced. Only a long time test will tell. So I will use this
charger sparingly. Lawrence Rhodes..
