battery keep draining

[robboscar]

Hi all

I have a 2004 diesel polo 1.4 150k on the clock, i only use it a couple of times a week mainly at weekends, but over the last couples of years it does'nt like the cold weather and struggles to start when not been used for about 4 days, so i have to jump start it to get it going but once it running its fine, i've had all the electrics checks and they can't fault it, it only seems to be a problem in the winter when its colder, but if i use it everyday it fine, any ideas would be helpfully.

Sounds like the battery is on its way out. Batteries struggle when left sitting, and especially when colder
