if the battery had full current, those batcaps should see well over 19v when fast charged

Chances are some of the cells are dead. Not much you can do at that point. Almost impossible to repair too.

Depending on how long it has sat, MAYBE it would help to try cycling - charging, then discharging a few times - but thats a big MAYBE.
