Jeff, Your car came new with a group 27, 12 volt battery that measures approximately 12" L x 6-3/4" W x 9" H to top of post. Any 12 volt group 27 size will fit. The higher the CCA rating, the better for cranking performance. Other factors to consider are appearance, maintenance, cost and availability. Those you have to decide on, there's a lot out there to choose from, it can be as simple as going to your local parts store and getting something that will work fine but not look original, or paying $250.00 for an original looking specimen. Some folks prefer Optima batteries for reduced maintenance. You decide.

Hi everybody, What size battery is suggested for a 413 L engine? The battery in it is CCA 525. I was thinking of getting a bigger battery as this old battery doesn't last long using accessories before its dead. The bigger battery I am considering is CCA 600 - would this be better suited with more punch for the mighty 413? I cannot find any info in my Manuel?
