At What Cca Should I Replace My Battery. Possibly in the fall or winter youll star. Choose a new battery with at least the specified CCA required by the lawn mower manufacturer.
Many automotive repair shops can test your battery with a special tester in the photo. There is no hard and fast rule though as to exactly when it should be replaced. The higher the CCA the better it will start in the cold.
On average a battery with 650 CCA is good for the cold climate.
It should be closer to 600 minimum at 55 degrees and more likely 700. But I have no difficulty starting the car on a cold morning. My lawn mower battery tested at 315 CCA. If you are replacing your cars battery it is not necessary for you to buy the same brand as the old battery but the replacement battery must have the same CCA rating.
