Exact dimensions, terminal layout and mounting base are confirmed according to the target vehicle and final housing configuration.
Reliable engine starting requires rapid delivery of high current while maintaining stable battery output. The featured 70Ah configuration is engineered for passenger-car and light-duty automotive cranking applications.
Provides strong short-duration current output for compatible gasoline and diesel passenger-car engines.
High-rate cell configuration and low-resistance internal connections support rapid current delivery during engine cranking.
Final CCA and battery configuration are selected according to engine displacement, fuel type, original battery rating and operating temperature.
Taxis, ride-hailing vehicles, rental cars and fleet passenger vehicles often operate on demanding daily schedules. Battery selection therefore requires reliable starting performance, consistent replacement specifications and convenient fleet maintenance.
| Urban Taxis Reliable starter battery solutions for high-mileage city operation | Ride-Hailing Vehicles Automotive replacement solutions for intensive daily vehicle use |
| Rental Car Fleets Standardized replacement batteries for managed vehicle fleets | Fleet Passenger Cars Customized fitment and product consistency for fleet programs |
| Working Temperature | −40°C to 80°C |
| Cold Starting | CCA Selected According to Engine and Minimum Ambient Temperature |
| Temperature Monitoring | Integrated Through Smart BMS |
| Overcharge Protection | Over-discharge Protection |
| Over-current Protection | Short-circuit Protection |
| High-Temperature Protection | Low-Temperature Protection |
| Cell Voltage Monitoring | Cell Balancing |
70Ah automotive batteries are available in different housing formats. The enclosure and terminals must therefore be matched to the original battery rather than selected by capacity alone.
| Housing Dimensions | Confirmed According to Original Vehicle Battery |
| Terminal Position | Customized Positive and Negative Layout |
| Terminal Type | SAE or Customized Automotive Terminal |
| Polarity | Left-Positive or Right-Positive |
| Mounting Base | Customized According to Battery Tray |
The sodium-ion battery can be developed as a replacement for a compatible lead-acid starter battery after complete vehicle and charging-system evaluation.
The featured 70Ah configuration can provide up to 1000CCA. Final CCA must be confirmed according to the selected battery configuration and test specification.
Yes. It can be configured for passenger-car fleet replacement programs after confirming the vehicle models, original battery specifications and charging systems.
The housing is confirmed according to the target vehicle. Different 70Ah automotive configurations may use different enclosure dimensions and mounting structures.
Yes. Voltage, capacity, CCA, dimensions, terminals, polarity and charging-system compatibility must be verified before replacement.
This product page is primarily positioned for conventional passenger-car engine starting. Start-stop applications require additional vehicle compatibility evaluation.
Please provide the vehicle brand, model, year, engine displacement, fuel type, original battery voltage, capacity, CCA, dimensions, terminal layout and charging-system voltage.
Send Chalongfly your vehicle model, engine specification, original battery CCA, housing dimensions, terminal layout and charging-system information. Our team will evaluate the application and recommend a suitable 12V 70Ah sodium-ion starter battery.
