Hi, I have a CR-V 2010. I have been dealing with the issue of dead-cold batteries for the last year. I am on my third battery and every time mechanics work on the problem find nothing wrong. No parasitic drainage, faulty alternator, voltage regulator....nothing. Reading others' owners post I am tempted to replace the AC relay by myselft since it happens to be a common issue amongs owners.
It is not a fix, but just try it and it will help you to narrow the source of the problem.
