The risk is that there is some sort of drain if the battery is connected, the point carmalade made. But mine seems to hold a reasonable charge for at least that long.
I'd either leave the charger connected, or disconnect the battery at the earth strap; maybe remove it altogether if you don't plan to start or use the car at all.

Mine has the ALDI one connected just now; I swapped the it for the CTEK when I used that to get the boss's dead battery charging. The MX5 has survived at least one winter connected to the ALDI one.

I mistakenly told you mine was a Westco - I'd forgotten that the one I ordered a while back was for friend down the road (I got the club discount). Mine is a Panasonic. It has the same yellow label and white numbers on the top as this one:

I think it might be original.
The Westco is completely different - I think the one I got looked like this:
