Mine starts first time every time even with occasional winter use - as should yours. Don't assume it is the battery, you sound like you may well have a parasitic current drain that you need to sort out first - the heaviest duty battery will still empty itself of charge unless this is sorted. Get the battery checked first to eliminate the battery as the cause, but don't just replace it without doing this, it could be money down the drain.
If the battery is OK, then you need to get the current drain measured with the ignition off. If you are handy with a multimeter then you can measure it yourself it but you may need an auto electrician. If you want to go the multimeter route then do a thread search as this has come up before.
It can be various things once you have identified the level of battery drain. The only foolproof method is to remove fuses one by one to see which one switches off the current drain.
