Caved in and finally bought a replacement (GS 46B24L (NS60L) 45Ah/20hrs) GF (doing the Taiwanese talking) said the "black hand" was just putting "liquid" in it when I arrived, which, if true, suggested it should be shiny and new.
My understanding is/was they were effectively almost fully charged at that point, but when I got it home I thought I'd give it a top-up.
Didn't, unfortunately, put a voltmeter on it before I started.
Charger (3 stage "smart" charger, allegedly) has three output settings "moped" (about 2 amps indicated usually) "motorcycle" (about 4-5 amps indicated usually) and "car" (about 6 amps indicated usually).
When I hooked it up on the "car" setting it was showing 8 amps, the highest I can remember seeing it do, suggesting the battery was pretty low.
Had to go out in a hurry and didn't want to leave it that high, and put it on the lower setting (instead of the lowest setting, which would perhaps have been better)
Now I'm back (11 hours later) and its still showing 5 amps. Turned it down.
So a couple of questions
Is this normal for a freshly flooded battery, which this was supposed to be?
Whats the optimal charging regime for a new battery? As low current as possible or trust the chargers alleged smarts and set it to "car"?
