[s-cars] Battery not liking the cold weather

[Tony Curran]

Hi folks,
 
My battery is 6.5 years old and struggling after standing outside in the
cold weather we're having up here in the cold white north.
 
Local dealer doesn't stock the Audi 191 915 105Q battery that's in the
vehicle. Are there any after market batteries that fit?
 
Thanks
