I've heard hissing when I definitely was overcharging, but I never
noticed hissing in normal operation.

Is it normal, or problematic, to replace AGM batteries and when you

Like a faint bubbling sound inside? It's possible they have always
done this and I've never heard it in the past because my ear wasn't
within a foot of the batteries.
Am I gonna have a boom?
BTW, I was wrong, the Zeus batteries are made in Vietnam now, at least
these were.
