my rover has been starting slower and slower. It's also getting colder and colder. Now it wont start at all in the morning and after work. It's turns over really slow untill it won't at all now.

I can jump it every time and it starts right up. I had auto zone check the laternator, and battery, and they said they were fine....that was a month ago.

ANybody please help.

 

Do the lights come on like normal?

 

What kind of battery and how many CCA's?

 

Follow the (-) negative terminal cable for the battery to where it bonds to the frame or chassis, and be sure those connections are also clean and tight. Maybe try another parts store, sometimes the tech suport on their side of the counter, or their test equipment may vary. Swap known good battery from another vehicle. Buy a used battery at junk yard for $25. Or a nice new one if you have not replaced it in say three years.

 

This leads me to believe the battery is bad and the connections/ground are good.
