New hab batteries

[Jugster]

Hi all
Just purchased brand new habitation batteries x 2. Still in boxes and fully charged. Now I know I have to replace the failed ones on the motorhome sometime, but my question is, should I delay replacing these until warmer weather arrives? Are they ok in the boxes? Will they deteriorate in the cold weather if on the van? They will be stored indoors in a warm house. The van is usually Plugged into ehu.
Hymer with 101 electroblock and solar.
Thanks

If you're not using the van I think it's best to keep them warm and charged until needed.
