What's the usual charge time 0->100% for a Lombard ?

On the charger it is charging very very slowly - after 4 hours it is at 65% and saying 2 hours to go to full charge.

Just switched on the G3 Lombard (400 mHz, 10.3.9.) after a month away and the battery was completely flat. On the charger it is charging very very slowly - after 4 hours it is at 65% and saying 2 hours to go to full charge.

So is 6 hours from 0 to 100% a "normal" charge cycle time for this unit in OSX - I don't remember it being so long under 9.2.2. a few months ago.
