How much should I pay for a good car battery?
A good car battery typically costs between ¥300 to ¥2,500, depending on battery type, brand, and vehicle requirements. Standard lead-acid batteries range from ¥200–¥500, while AGM/EFB batteries for start-stop systems cost ¥800–¥1,500. Lithium-ion variants exceed ¥2,000, primarily for high-performance EVs.

What factors determine car battery pricing?
Battery chemistry, capacity, and brand reputation drive costs. Lead-acid remains budget-friendly, while AGM/EFB batteries justify higher prices with 3× longer lifespan and vibration resistance.
Technical specifications like cold cranking amps (CCA) and reserve capacity (RC) directly impact pricing. For example, a 12V 70Ah AGM battery with 760 CCA costs ¥1,200–¥1,800, whereas a basic 60Ah lead-acid unit averages ¥400. Pro Tip: Always match battery group size (e.g., H6, DIN66) to your vehicle’s tray—incorrect dimensions risk installation failures. Transitional note: Beyond capacity, consider climate—AGM batteries outperform in extreme temperatures despite higher upfront costs.
| Type | Price Range | Lifespan |
|---|---|---|
| Flooded Lead-Acid | ¥200–¥500 | 3–4 years |
| AGM/EFB | ¥800–¥1,500 | 4–6 years |
| Lithium-Ion | ¥2,000+ | 8–10 years |
How do start-stop systems affect battery costs?
Start-stop technology mandates AGM/EFB batteries, which cost 2–3× more than standard units due to enhanced cyclic durability and deeper discharge tolerance.
These batteries endure 30,000+ engine restarts versus 5,000 for conventional units. A Volkswagen Golf’s EFB battery (¥1,100) handles frequent cycling but requires compatible charging systems. Warning: Using regular batteries in start-stop vehicles causes premature failure—their thin plates degrade under repeated high-current draws. Transitional note: Practically speaking, AGM batteries also support advanced electrical loads like lane-keeping systems. Did you know? Some luxury models use dual-battery setups, combining AGM with lithium for peak efficiency.
| Feature | AGM Battery | Standard Battery |
|---|---|---|
| Cycle Life | 500+ cycles | 200 cycles |
| Vibration Resistance | 3× higher | Basic |
| Recharge Efficiency | 95%–99% | 80%–85% |

FAQs
No—standard batteries lack cyclic durability for frequent engine restarts, risking sudden failures and ECU errors.
Does battery brand significantly affect performance?
Yes—premium brands like VARTA and Bosch optimize plate alloys and separators, achieving 15%–20% longer service life versus generic units.
