Frequently Asked Questions

• Will switching to an Aeson Power sodium-ion starting battery lower costs?

  Lower Total Cost of Ownership: Although the initial purchase cost is higher than that of regular lead-acid batteries, because its lifespan is more than 3 times longer, it saves on the labor and time costs of frequent replacements.

  Improved Fuel Economy: The battery significantly reduces weight (by over 10 kg). Coupled with its more efficient charge acceptance capability, testing has proven it can deliver up to 5% fuel savings for internal combustion engine vehicles.

  
  

• How does the Aeson Power sodium-ion starting battery tolerate such a harsh environment?

  The high temperature of the engine bay is the Achilles' heel of traditional batteries (lead-acid is prone to bulging, lithium is prone to overheating and catching fire). However, Aeson Power sodium-ion batteries utilize a polyanionic framework structure with extremely high thermal stability. Their thermal runaway critical point is much higher than that of traditional batteries. Under the extreme heat of an 80°C engine bay, the structure suffers no damage, and no internal vaporization occurs. Combined with the high-temperature charging protection of the intelligent BMS, safety hazards such as leakage and deflagration are mitigated, ensuring that its lifespan is not compromised under high temperatures.

• Why are Aeson sodium-ion starting batteries over 60% lighter than traditional lead-acid batteries?

  Generational Difference in Materials: The core positive and negative electrodes of sodium-ion batteries use lightweight carbon materials and polyanionic compounds, and the internal electrolyte is replaced with a lightweight organic solvent. The density of these materials is far lower than that of heavy metallic lead.

  3x Difference in Energy Density: The energy density of traditional lead-acid batteries is usually only 30-50 Wh/kg, whereas the energy density of Aeson Power sodium-ion batteries can reach 100-140 Wh/kg. This means that under the premise of storing the same amount of electricity and providing the same cranking current, the weight of the active material required by a sodium battery is less than one-third of that of a lead-acid battery.

  
  

• 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..
