If you think about it, its not going to be the battery, your getting power to the starter motor which is one of the biggest power drainers on the vehicle as its gotta turn every thing around to start the engine, and you say you plugged it into a charger which said its fine? so that would tell me that the battery is A OK.
Take your spark plugs out with the HT leads still attached, place the electrodes one at a time onto the fins of the barrels to earth them and press your starter button, you should get a spark, do this on both plugs, if no spark then buy new plugs and do the same again. If still no spark then you will need new coils,
Also when before you take the plugs out try to start it then take plugs out to check if they are wet with fuel, if there is no fuel on the plugs then there is a fuel problem. Either fuel pub shagged, clogged hose or just no petrol in the tank lol.
Try this then report back
