I too have seen increased water usage in older batteries. I don't recall noticing some batteries or cells using dramatically more, but then it's not something I paid a lot of attention to. I've mostly just stuck the gurgler can in and let it go until it stopped when watering. I think the reason for the increased water use may be that most automatic chargers keep trying to charge old batteries to the same finishing voltage as when they were new. An aging battery has a lower fully-charged voltage because it's lost active material. However, I'm just a hobbyist, not an electrochemist.
