Parts store will bench test yours.l
I'd also check for loose connections.
Plus I pull the 30 amp fuse before charging.
That way I can see if battery discharge is outside of battery and hot short in the wiring is to blame.
All of this before I buy a battery.
I'll let other replies recommend a new battery.

Like above get the battery tested, even a new battery can go bad. Additionally, make sure your tender is connected and working properly. A Volt Ohm Multi Meter is your friend.

My bike has stock HD battery and is into its 4th winter. So far so good.
My partners machine would be fine in the summer but fails to start in the cold weather even though it is on a tender.
I have just put a Yuasa YTX14L-BS on it. Only one start so far in the cold and it fired up right away.

As it is six months old, is it in warranty?
