Rechargeable batteries do charge between 13.2v to 14v, depending on the charger and battery condition.I use batteries and chargers a lot at work for film camera equipment which are virtually the same as bike and car ones, and a good battery will normally drop down to between 12.8v and 13.2v when idle after charging, and when you remove the charger it's normal to watch it slowly drop down until it settles.It does kind of point to a dud battery to be honest.

Cheers guys. My concern was there might be a deeper fault such as the regulator, but it appears that it's just a knackered battery from from what you are saying.Down to the local battery store for me (if such a place exists!!)
