What this shows is that there's a flicker of life in them thar cells.
It might be worth your while to work on that battery a bit longer. I have a Type 3 battery that began more or less like yours, but that I can now get fully 2 hours charge out of on a 68030 Duo with all its power saving features enabled. Not bad for a set of cells from the early-to-mid 90s. (On a 280c, the charge is more like 80 mins., so it was not for nothing that the 280c required a 36W as opposed to the older 24W Duo adapter.)
I should add, mind you, that I have not had such luck in rehabilitating several Type 1 batteries that I have lying around. But most of them are unlike yours in that they show no signs of life at all.
