EV1280 Technical Specifications

Final specifications and vehicle compatibility should be confirmed with Enervolts before replacement installation or OEM production.

1650A CCA for Reliable Engine Starting

Cold Cranking Amps are one of the most important parameters when selecting an automotive starter battery.

The EV1280 provides:

• 1650A CCA
• 2400A starting current
• 4800A cranking current
• 1200A continuous discharge current

This high-current capability is designed to provide reliable ignition for compatible passenger vehicles, SUVs and light commercial applications, including demanding cold-weather starting conditions.

Vehicle suitability should be evaluated according to engine displacement, original battery CCA and electrical-system requirements.

Cold-Weather Starting Down to -40°C

Conventional starting 12V sodium ion car battery can experience reduced output as ambient temperature drops.

The EV1280  is specified for operation from -40°C to +80°C, making it particularly suitable for automotive markets exposed to severe winters or large seasonal temperature changes.

For battery distributors serving cold-climate regions, the EV1280 offers a sodium-ion option for applications where dependable winter cranking is a key purchasing consideration.

Actual cold-start performance depends on battery SOC, engine condition, ambient temperature and vehicle electrical load.

80Ah Capacity for Passenger Cars, SUVs & Vans

With 80Ah / 960Wh capacity, the EV1280 sits between smaller compact-car starting batteries and larger 100Ah high-power models.

This makes it particularly relevant for:

• Mid-size and large passenger cars
• SUVs and crossovers
• Vans
• Start-stop vehicles
• Automotive aftermarket replacement
• Fleet battery programs

For applications requiring a larger-capacity starting battery, view the 12V 100Ah sodium ion car battery.

Automotive-Size Housing for Replacement Projects

The EV1280 housing measures approximately:

314 × 175 × 190 mm

This corresponds closely to a common European automotive battery footprint and should be evaluated together with:

• Battery tray dimensions
• Terminal position
• Battery height
• Original battery capacity
• Required CCA
• Charging voltage
• Vehicle start-stop requirements

Do not select a replacement battery based only on Ah capacity. Mechanical and electrical compatibility should be confirmed before installation.

Bluetooth Battery Monitoring

The EV1280 supports Bluetooth communication, providing a convenient way to monitor battery operating information through a compatible monitoring system.

This feature can be useful for:

• Fleet battery management
• Battery distributors
• Automotive aftermarket brands
• Vehicle maintenance teams
• OEM smart-battery projects

Bluetooth functionality can also strengthen the value proposition of private-label automotive batteries by adding digital battery-status monitoring.

IP65 Protection for Automotive Environments

The EV1280 is rated IP65, providing protection against dust and water exposure encountered in typical automotive installation environments.

Battery installation should still follow recommended mounting, ventilation and terminal-protection practices.

3000+ Cycle Design

The EV1280 is designed for more than 3,000 cycles under specified operating conditions.

For start-stop vehicles and other applications involving frequent engine restarts, cycle durability is an important factor when comparing battery technologies.

Actual service life depends on:

• Start-stop frequency
• Depth of discharge
• Charging strategy
• Ambient temperature
• Vehicle standby consumption
• Storage conditions

For this reason, cycle count should not be converted directly into a fixed number of service years without considering the actual operating profile.

Deep-Discharge Recovery

The EV1280 is designed to support recovery after deep discharge to 0V under specified conditions.

This characteristic can be beneficial for vehicles or inventory that may remain unused for extended periods.

Proper recovery charging procedures should be followed before returning a deeply discharged battery to service.

Is the EV1280 Suitable for Your Vehicle?

Before selecting an 80Ah sodium ion starter battery, compare the EV1280 with the vehicle's original battery specification.

For assistance, customers can provide the original battery model, dimensions, Ah, CCA, engine displacement and vehicle application for evaluation.

FAQ

What is the capacity of the EV1280?

The EV1280 is a 12V 80Ah sodium ion car starting battery with approximately 960Wh of stored energy.

What is the CCA of this 80Ah sodium ion battery?

The EV1280 is specified at 1650A CCA, with 2400A starting current and up to 4800A cranking current.

Can the EV1280 start vehicles in very cold weather?

The specified operating temperature range extends down to -40°C. Actual starting capability depends on engine displacement, state of charge, vehicle condition and ambient temperature.

Is the EV1280 suitable for start-stop vehicles?

Its high current capability and 3000+ cycle design make it suitable for evaluation in start-stop applications. Vehicle charging parameters and system compatibility should be confirmed before installation.

Is this an H7, H8 or H9 battery?

The published dimensions are approximately 314 × 175 × 190 mm. Buyers should use the actual physical dimensions and terminal configuration when checking fitment rather than relying only on H-size terminology.

Can it replace an AGM or EFB battery?

The EV1280 can be evaluated as a sodium ion alternative for compatible AGM or EFB starting-battery applications, but it should not be described as a sodium-ion AGM battery. Size, CCA, charging voltage, terminals and vehicle compatibility must be verified first.

Does Enervolts support OEM and private-label orders?

Yes. Enervolts supports OEM and ODM projects involving battery specifications, housing, BMS, Bluetooth functions, branding and packaging.
