Frequently Asked Questions

• Why does Aeson Power only require one battery when traditional heavy-duty trucks and commercial vehicles use two 12V lead-acid batteries connected in series?

  
  

  Due to the cell voltage limitation of traditional 12V lead-acid batteries (about 2V), 6 cells must be connected in series. To achieve the 24V system required by commercial vehicles, two 12V batteries must be physically connected in series outside the vehicle using thick, heavy cables. In contrast, the Aeson Power 24V sodium-ion battery performs highly efficient cell-level series connection directly inside a single battery pack (with modular BMS management), serving as a single battery with high CCA that directly outputs a 24V voltage.

• In which specific equipment and business scenarios can the Aeson Power 24V sodium-ion starting battery be applied?

  Diesel engines (construction machinery / generator sets), light trucks (high-frequency start-stop / urban distribution transport), and air compressors (high vibration / harsh outdoor environments).

• 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 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..
