The 70mai Li-ion 3.7V 500mAh battery is engineered for reliability in dash cams like Smart Dash Cam Pro and Midrive D02. Its compact design (14x50mm), EVE cell technology, and 3-wire plug ensure seamless power backup during ignition cycles. With included installation tools, it addresses voltage stability and longevity, outperforming generic alternatives. Perfect for users prioritizing safety and uninterrupted recording.
How Does the 70mai Battery Ensure Compatibility with Dash Cams?
The 3.7V 500mAh Li-ion cell matches voltage requirements of 70mai dash cams. The 14x50mm size fits proprietary compartments, while the 3-wire plug aligns with OEM connectors. EVE Battery’s low self-discharge rate prevents data loss during parking mode. Compatibility extends to Midrive D02 and HMC1450 models, validated via firmware synchronization.
What Safety Features Protect the 70mai Battery from Overheating?
Built-in PCM (Protection Circuit Module) prevents overcharging, over-discharging, and short circuits. Thermal sensors regulate temperature during extreme conditions. The Li-ion chemistry minimizes swelling risks, while flame-retardant casing complies with UL/IEC standards. Users report zero incidents of thermal runaway in stress tests.
Why Choose EVE Battery Cells Over Generic Alternatives?
EVE cells offer 500+ charge cycles (vs. 300 in generic Li-ion), maintaining 80% capacity after two years. Precision welding reduces internal resistance, enhancing energy density. Third-party tests show 15% longer runtime in sub-zero temperatures. EVE’s ISO-certified manufacturing ensures consistency—critical for dash cam power stability.
Differences Between Eve and Other Brands
EVE’s proprietary electrode coating technology improves ion mobility, enabling faster charging without compromising cell integrity. In controlled tests, these batteries maintained stable voltage output even during simultaneous GPS logging and 4K video recording. The table below highlights performance differences:
| Feature | EVE Cells | Generic Cells |
|---|---|---|
| Cycle Life | 500+ | 250-300 |
| -20°C Performance | 85% capacity | 62% capacity |
| Voltage Stability | ±0.05V | ±0.15V |
What Environmental Factors Affect the Battery’s Lifespan?
Prolonged exposure to >45°C or <-10°C degrades capacity. Humidity above 80% risks corrosion. EVE’s moisture-resistant coating mitigates this. For optimal life, avoid direct sunlight (use sunshades) and update dash cam firmware to optimize power draw.
Thermal cycling—repeated heating/cooling during daily use—can accelerate electrode wear. Parking garages with stable temperatures extend battery life by 18-22% compared to street-parked vehicles. Users in desert climates should inspect connectors quarterly for oxidation. The battery’s built-in thermal hysteresis protection pauses charging if ambient temperatures exceed safe thresholds, preventing permanent damage.
Are Firmware Updates Required for Battery Integration?
70mai dash cams post-2021 auto-detect the battery via handshake protocols. For older models, firmware v2.3.6+ adds charge-level indicators. Updates are free via 70mai’s app—no compatibility errors reported.
“The 70mai battery’s use of automotive-grade PCM sets it apart. Most aftermarket batteries skip this to cut costs, risking voltage spikes. Its integration with parking mode algorithms ensures cams don’t drain car batteries—a common pain point.”
— Automotive Electronics Engineer, 70mai Partner“EVE’s cell consistency is unmatched. We’ve tested 100+ units; all delivered within 5mAh of rated capacity. For dash cams, even a 50mAh drop can mean missing critical footage during outages.”

FAQ
- Does the battery support 24/7 parking mode?
- Yes, for up to 48 hours (depending on temperature and recording resolution).
- Can I use this battery with non-70mai dash cams?
- Only if they share the 3-wire connector and 14x50mm compartment. Check voltage requirements first.
- How do I recycle the old battery?
- Return it to 70mai’s e-waste program or certified Li-ion recycling centers. Never dispose of in household trash.
