A car battery replacement runs $120 to $300 installed at most shops or auto-parts stores. AGM batteries (in most newer cars with start-stop) cost more. Many parts stores install free with purchase. Here is what you should actually pay.
Most drivers pay $150 to $220 installed for a quality flooded or AGM battery at an auto-parts store.
Standard flooded is cheapest. AGM (start-stop systems) costs 50-80% more. EFB sits in between.
Larger group sizes cost more.
Higher CCA = higher cost. Match the original spec.
Costco/Walmart/parts-store house brands beat name brands on value.
Many newer cars need a battery management system reset via scan tool, adding $20-$80.
Some cars (BMW, Audi, certain Chevys) hide the battery in odd places, raising labor.

Typically 4-6 years. Hot climates shorten life to 3-4 years. Short trips and heavy accessory use also reduce lifespan.
Required (not optional) on start-stop cars. On other cars, AGM lasts longer and handles deep discharge better, but the extra cost is not always worth it.
Modern battery management systems track battery age and adjust charging rates. Without a reset, the car overcharges or undercharges the new battery.
You can - until you cannot. Once it stops cranking, you are stranded. Replace before that happens.
