Nobody wants to sell flooded batteries wholesale unless they have to.
If you're buying retail look at the larger models that have external
battery terminals. Not that you can't replace AGM bettries with
flooded batteries so long as you house the batteries correctly

I'm assuming by wet cells you mean a sealed lead acid battery. I have a
Digitech MP5205 that has a VRLA (SLA) 7Ah 12 V battery for the UPS side
of things. I see some models of APC UPS have the same battery and, I
think, also Eaton. Even my NBN wall box has the same battery in it. They
are fairly ubiquitous. Obviously they come in different sizes but most I
have used seem to have a 7 or 9 Ah VRLA battery. Because they are valve
regulated they can be safely used in a home/office environment.

Nothing astonishes Noddy so much as common sense and plain dealing.

Nope, consumer UPSes only use SLA or AGM batteries. Wet cells vent gas,
and aren't suitable for most consumer applications.

Can you tell us why you want wet cells?

Just so long as I can adjust the charging voltage(down I think it is).

Even if I wanted to do that(continually replace SLAs in the NBN UPS boxen,
it still doesn't givem me a phone in a blackout without another UPS for
some combination of (router, POE switch and VOIP handset).

P.S. SLA=/=wet cell.
