Replacing a BMW battery can cost between $300 and $500 at a dealership. However, you can save approximately $200 by purchasing a compatible battery and installing it yourself.
BMW Battery Types and Replacement Costs
BMW vehicles typically use either lead-acid or AGM batteries. Lead-acid batteries are more affordable but have shorter lifespans. AGM batteries offer better performance and longevity but come at a higher price. Knowing the type of battery your BMW requires will help you budget effectively.
| Battery Type | Average Cost | Lifespan | Performance |
|---|---|---|---|
| Lead-Acid | $150-$250 | 3-5 years | Standard |
| AGM | $250-$400 | 4-7 years | Enhanced |
The cost of the battery is just one aspect. You should also consider labor costs if you opt for professional installation. Many dealerships charge a premium for labor, which can add $100 to $200 to your total bill.
