Haven't had any starting issues with my battery as of yet (touch wood ), apx 4 years old. However I'm going camping in the cold(-5c to 5c with possible snow) in 3 or so weeks, and really don't feel like getting stranded etc.
Took my car into Supercheapauto today for a load test, and the battery appeared to 'pass', but with a measured 516CCA, against a 680CCA battery rating.

Not entirely sure if my battery is fully charged as I haven't done a longer drive (>30mins) in more than 6-8 weeks. Unsure if that would affect the CCA or not.

Any solid advice would be appreciated.

Took the car for a drive over an hour, and re-tested with basically the same results results.
Ended up grabbing this with 720CCA from supercheapauto while they had their 25% off century batteries deal going.
Would rather have piece of mind, than car not turn over in the cold weather with no phone reception this coming winter.
