Backup Starting Power

Can be configured for emergency starting or auxiliary starting applications, subject to the required current and connection method.

Environmental Operating Range

The battery is designed to operate in environmental temperatures from -20°C to 65°C.

For reliable operation:

• Avoid continuous exposure to temperatures above the specified range.
• Avoid charging below 0°C unless specifically permitted.
• Keep the battery away from direct flames and excessive engine heat.
• Do not install the battery where water can accumulate.
• Ensure the terminals remain clean and secure.
• Avoid prolonged storage in a fully discharged state.

Environmental temperature affects starting current, charging efficiency, available capacity and battery service life.

Transportation and Certification

The battery is designed to meet UN38.3 transportation testing requirements.

UN38.3 testing is commonly required for lithium and sodium-based batteries transported by:

• Air
• Road
• Rail
• Sea

The testing process evaluates battery performance under transportation-related conditions such as altitude simulation, thermal cycling, vibration, shock and external short circuit.

For export projects, buyers should request the current test summary, safety data sheet and shipping documentation for the exact battery model being ordered.

Additional certification requirements may depend on the destination market, vehicle type and final application.

Battery Installation Guidelines

Installation should be completed by qualified automotive or electrical personnel.

Before installation:

1. Switch off the vehicle and all electrical equipment.
2. Confirm the battery voltage and vehicle compatibility.
3. Check the terminal position and polarity.
4. Inspect the battery tray and hold-down structure.
5. Remove the negative cable before the positive cable.
6. Install the new battery securely.
7. Connect the positive terminal before the negative terminal.
8. Confirm that all connections are tight.
9. Verify the charging voltage after engine startup.
10. Check for warning indicators or abnormal battery behavior.

Reverse polarity can damage the battery, vehicle electronics and charging system.

Charging Compatibility

The battery must be charged using a compatible automotive alternator or sodium-ion battery charger.

Important charging parameters include:

• Charging voltage range
• Maximum charging current
• Temperature conditions
• Float charging behavior
• Alternator regulation
• Vehicle battery monitoring logic
• Low-temperature charging restrictions

An incompatible charging system may cause BMS protection, incomplete charging or reduced battery life.

For vehicles with intelligent alternators or battery management sensors, additional compatibility verification may be required.

Storage Recommendations

For batteries that will not be used for an extended period:

• Store the battery in a clean and dry location.
• Avoid extreme temperatures.
• Disconnect the battery from parasitic loads.
• Check the battery voltage periodically.
• Recharge according to the recommended storage interval.
• Do not store the battery in a deeply discharged condition.
• Protect the terminals against accidental short circuits.

Storage conditions can affect battery capacity, starting performance and service life.

Information Required for Battery Selection

To confirm whether the battery is suitable for a specific vehicle or project, provide the following details:

This information helps verify starting performance, fitment and charging compatibility.

Frequently Asked Questions

What is a sodium-ion starting battery?

A sodium-ion starting battery uses sodium-ion electrochemistry to store and release electrical energy. It is designed to provide high current for engine starting and selected 12V power applications.

How much energy does a 12V 20Ah battery store?

A 12V 20Ah battery stores approximately 240Wh of nominal energy. Actual usable energy depends on discharge current, temperature and protection settings.

Can this battery replace a 12V lead-acid battery?

It can replace selected 12V lead-acid batteries when the voltage, dimensions, terminal layout, charging system and cranking current requirements are compatible.

Is a 20Ah battery suitable for starting a car?

Battery capacity alone does not determine starting suitability. The required CCA, peak current, engine size, temperature and starter motor demand must also be checked.

Can the battery operate in winter?

The battery is designed for environmental operating temperatures down to -20°C and offers strong low-temperature starting performance. Charging below 0°C should be avoided for optimal performance.

Does the battery include a BMS?

Yes. The active BMS provides cell balancing and protection against low voltage, high voltage, short circuit and abnormal temperature.

Can it be used in a start-stop vehicle?

It is suitable for selected automotive start-stop applications. Compatibility with the vehicle charging and energy management system must be confirmed before installation.

Is the battery maintenance-free?

The battery does not require acid inspection or water refilling. Users should still inspect the terminals, mounting, voltage and operating condition periodically.

Does the battery meet shipping requirements?

The battery meets UN38.3 transportation testing requirements. Shipping documents should be confirmed for the exact model and destination.

What details should I provide before ordering?

Provide the vehicle model, engine type, original battery specification, required CCA, battery dimensions, terminal layout, charging voltage and order quantity.
