If I leave the car for a few days it will start first time less then 2 secs but if I am waiting for the mrs when she is in the shop / asda and I side lights and radio are on for a little bit then when I go to start again it takes time to start like the battery is a little flat now the radio and side lights should not take that much power from the battery as the radio as a 1 hour play without the engine on and side lights are nothing of HIGH power where can I start to look as maybe the battery is fine as I left the car for 4 days and here was
1c -2 c and it took less then 2 secs to start .... Thx

 

I'm struggling to decipher your post due to the lack of punctuation..

The radio and parking lights shouldn't draw too much, are you doing long runs or constant short runs? Whats the voltage of the battery after a night it hasn't been driven?

Could be a simple weak battery, the cold puts a strain on it but i'd check the voltage to start with.

 

It starts fine if it's been cold after left for a few days but 5-10 mins using lights radio then it's takes longer to start like the battery is going

 

It shows that your radio and other lighting have some short circuit because some time if the wires have remove their insolution from them by accidently or may be your car is too old so they touch with each other which can weak the battery. You can check them. If they are ok then I think its not a big problem you have to run the car over 1 or 2 hours and then the battery will again charge itself. gud luck...!!
