2004 PT cruiser (i know) battery drain Car wouldn't start the other day - just clicked. Jumped and ran fine.

Next morning - battery dead again. took to advance auto and had it trickle charged. the battery then tested as ok with their fancy battery tester.

reinstalled battery, had advance run charging system check. Showed no problems with alternator, but did not detect engine rev.

battery is now dead again. it took about a day for it to drain.

The battery cables are a bit corroded, and there is a known issue with the positive cable wearing through the insulation in one spot. Any input on if I should go ahead and change the battery cable assembly now? We haven't had issues with battery drains in the past.
