The fazer battery is a sealed unit and is only suitable for charging with trickle chargers. The Argos charger is not suitable as it will charge the battery to fast and damage it in one of two ways , buckle the plates or cause evaporation of the acid and being sealed you cannot replace the acid. It is only suitable for unsealed lead acid type batteries. This one appears to be more like what you require if buying from Argos http://www.argos.co.uk/static/Search/sea...HARGER.htm
As AdieR says it is possible that you journeys are to short or to slow to charge the battery fully and it will discharge eventually. It this is the case I would suggest you take a longer way home every second or third day. Full charging only occurs above 5000rpm therefore if you are doing a lot of stop start riding in traffic and short journeys it will eventually discharge.
Battery life is around 4 to 7 years depending on use/care and it is possiblle it is on the way out. Some expire gradually as cells deteriote (12 volt batteries have 6 cells) gradually, eventually one of the cells packs up. If this happens the battery will only start the bike on the first try and if the first try fails it will not have sufficient charge for a second try. The battery specialists have a special device for checking batteries to see if cells are beyond salvage, but before you splash out on a new battery try the recommendation above first.
