The original battery of my 2003 Fazer died after 3 years, the replacement I got at the time which was exactly the same model as the original is still going after 6 years. No hard and fast rule in relation to the lasting time, but most batteries should last between 4 and 7 years which means mine is not long for this world. I have seen new batteries die after 2 to 3 years and even one after 6 months. If the battery was treated well then you were probably unlucky. It would not do any harm to check all the connection and spray them with WD 40 to keep the corrosion at bay.
The charging specifications say 14V/365 W at 5000 rpm but that would be with no load. Lights on and resistance of wires, a bit of corrosion etc. could drop it to 13.7.
