Does Duracell make automotive batteries?
Yes, Duracell manufactures automotive-grade batteries designed for specific vehicle applications. Their product line includes 3V lithium coin cells (e.g., CR2016, CR2025) optimized for car key fobs, tire pressure monitors, and electronic control units. These batteries deliver stable voltage output in extreme temperatures (-30°C to +60°C) and feature a 10-year shelf life. However, Duracell does not produce traditional 12V lead-acid starter batteries for engine ignition or EV traction batteries for electric vehicles.

What automotive components use Duracell batteries?
Duracell batteries power low-voltage automotive electronics like keyless entry remotes and onboard computers. Their CR-series coin cells maintain 3V nominal voltage with ≤0.1V drop under 100mA loads, ensuring reliable signal transmission to vehicle receivers.
Key applications include Mercedes-Benz and Nissan smart keys, where Duracell’s anti-leak design prevents corrosion in compact circuits. Pro Tip: Replace key fob batteries every 2–3 years—diminished voltage causes intermittent locking failures. For example, a depleted CR2025 might still power LED indicators but fail to transmit radio signals beyond 3 meters.
How do Duracell automotive batteries compare to competitors?
Duracell’s automotive cells outperform generic brands in extreme temperature resilience, sustaining 95% capacity at -20°C versus 60–70% for budget options. Their zinc-air chemistry enables faster discharge recovery after cold cranking.
| Parameter | Duracell CR2032 | Generic CR2032 |
|---|---|---|
| Operating Temp | -30°C to +70°C | -10°C to +60°C |
| Pulse Current | 15mA | 8mA |
| Shelf Life | 10 years | 5 years |
Transitioning to real-world performance, Duracell batteries maintain signal strength in snowy conditions where competitors falter. Ever wonder why luxury car manuals specify brand-name cells? Voltage stability directly impacts encrypted key-code validation systems.

FAQs
No—these 3V batteries lack the 200–800 cold-cranking amps required for engine ignition. Use only approved 12V lead-acid or lithium starter batteries.
Do Duracell car key batteries expire?
Yes, all lithium cells degrade over time. Check manufacture dates stamped on packaging—install batteries produced within the last 3 years for optimal performance.
