Does a 05 tahoe require a bigger battery?
2 Answers
Your Tahoe takes a group size 78 battery. Within that group size you have a choice of CCA (Cold Cranking Amps). This is the amount of amps the fully charged battery puts out at 0°F when you start the engine. If you live in a colder climate a higher CCA battery is better, especially during the cold winter months. If you don't live in a colder climate, a lower CCA battery will be just fine. Hope that helps! Jim
