Frequently Asked Questions

• Which high-frequency application scenarios are Aeson Power 12V sodium-ion start-stop batteries mainly suitable for?

  During urban morning and evening peak hours, and on heavily congested roads with dense traffic lights, a vehicle's automatic start-stop system faces its most frequent and severe tests. Aeson Power sodium-ion start-stop batteries are born precisely for these scenarios. Tailored for extremely harsh stop-and-go road conditions, this battery features a start-stop cycle life of up to 180,000 cycles, leaving it completely unfazed by high-frequency engine shut-offs and instantaneous high-current ignitions.

• What are the advantages of the Aeson Power 12V sodium-ion battery compared to traditional lead-acid or AGM batteries?

  The Aeson Power 12V sodium-ion start-stop battery achieves a generational leap over traditional lead-acid batteries.It boasts an ultra-long cycle life of over 3,000 cycles, essentially eliminating the need for replacement throughout the vehicle's lifespan.With its extremely low internal resistance, it can deliver an ultra-high cold cranking amps (CCA), resulting in crisper ignition during extreme cold or frequent start-stop conditions.It reduces weight by 60% compared to traditional batteries of the same capacity, significantly helping to lower overall vehicle energy consumption.At the same time, it possesses a powerful 0V-level deep discharge recovery capability, allowing it to "revive to full capacity" via jump-starting even if completely drained. It is also a green, non-toxic lead-acid battery alternative, free from thermal runaway risks, making it a more efficient, economical, and absolutely safe epoch-making choice.

  
  

• What is the charging voltage? What is the full charging voltage?

  Charging voltage range: 14.4~14.8 V. Recommended maximum charging voltage is 14.6V (12V).

  Usually the open circuit voltage is between 13~14.5V after fully charged and rest for about 30min.

  
  

• What is a start-stop battery?

  A start-stop battery is a specialized automotive battery engineered specifically for modern vehicles equipped with an automatic Start-Stop system. Unlike conventional vehicles, start-stop vehicles automatically shut off the engine when idling (e.g., at red lights or in traffic jams) to conserve fuel and reduce carbon emissions. The engine must then restart instantaneously as soon as the driver releases the brake or engages the clutch.

• What are the main functions of the Aeson Power 12V sodium-ion automotive start-stop battery?

  Start-stop batteries possess all the functions of a starting battery within the vehicle. Additionally, when the vehicle is stationary and the engine is not running, they supply energy to various electrical appliances on board; when the engine stops, they must ensure that the complete electronic system functions normally, including the power required for the next start.  

• Sodium battery charging time？

  The charging time is related to the charging voltage and the charging current. For example, with 0.2C current and 14.6V voltage, the full charge time is about 5.5h; while with 1C high current, it isabout 1.1h. Normally, the charge voltage reach the limit value and last for 6-10min means it fully charged.

• What is the discharge voltage (working voltage, i.e., closed circuit voltage in work) of sodium battery?

  The discharge voltage is related to the size of the load and the SoC state of the battery. Thesmaller the load, the higher the voltage; the higher the SoC, the higher the voltage.

  The closed-circuit voltage range of a new battery for start-stop use is between 9 and 12V, and thevoltage will gradually drop during usage.

  
  

• Do sodium batteries require maintenance?

  Sodium-ion starter batteries are a fully sealed & maintenance-free design, so these are similar to those of lead-acid AGM battery types. The original meaning of the English term MF(Maintenance Free) in the lead-acid battery terminology is that it does not require regular topping.

• How are sodium batteries recycled?

  Since sodium-ion starting batteries are a new technology and still in the stage of continuousimprovement, there is no comprehensive recycling standards and regulations yet, the relevantrecycling specifications are basically still referred to lithium-ion batteries, and it is recommended to consult the local professional organizations at present.

• Are sodium batteries considered dangerous goods in transportation?

  Yes, now basically refer to lithium-ion products regulation.

• How to operate the sodium battery after over-discharged?

  It is recommended to place it in 5~35℃ environment, and then recharge it according to therecommended method. In order to better protect the battery and avoid the damage caused byover-discharge, please recharge it if the battery voltage is less than 1ov.

• How do I maintenance a sodium-ion battery during long time storage?

  Short-term storage (1-3 months): generally no special maintenance is needed. Regularvoltage checks are recommended in higher temperatures (>35°C) to prevent excessiveself-discharge.

  Medium-term storage (3-6 months): Possible 5%~20% capacity loss; check voltage every 3months. Recharge if the voltage drops to 10V per 12V.

  Long-term storage (6 months or more): Possible 20%~40% capacity loss; recommendingCharge to 40%~60%soC to prevent irreversible damage for long time storage management..
