A few times in the last week our '10 Journey SXT has not wanted to start. Basically I'd turn the key and only get a click. But eventually it would get a good connection and start. Was only happening occasionally. Put my multimeter on it and got 12.3 volts at rest and 13.3-13.6 volts with the engine running. Had Advance check it and it came back as slightly weak. Only registering 450 CCA. Battery rated at 525 CCA. Was almost going to pull the trigger on a new battery (~$110), but something told me not to. Decided to stop and get a battery brush on my way back from the dump (took the Ram of course). After fussing and cussing I finally managed to gain access to the battery (whoever decided in front of the LF fender well was a good place for the battery should be shot!). Had to jack the left front up and remove the wheel. Then fight with the plastic doo hickies that secure the fender covers. Finally to the battery. Not much room in there, but finally managed to get the cables removed. Posts and cables had a slight film on them. No real corrosion. Cleaned the posts and cables to a nice shine. Reassembled. Checked voltage. Got 12.6 volts at rest and 14.3 volts with engine running. That's more like it! You wouldn't think a slight build up of film would make that much difference. So the moment I have been able to put off the purchase of a new battery. I know it'll need replacement soon as it is 5 years old. Car was manufactured in August 2009 and I believe it is the original OEM battery.
