If you live in an European country where the EC Directive is in place, a battery is covered by the 2 year warranty. This consumable thing is a manufacturer invention , to cover up the low quality batteries in laptops. If you look closely at the definition of the word consumable , it says : That may be depleted or worn out by use. The latter thing is interessing because that's what exactly happens to a harddisk. But the manufacturers are not excluding harddisks, aren't they. Of course , some states in Europe could have an exclusion clause for batteries but it's certainly not in the EC Directive and not in country where i live.
