When pharmaceutical companies sell medicines/vaccines to drugstores/clinics/hospitals, the lid of the box need to be open several times as they go to drugstores/hospital/
clinic. For this reason, there is a possibility of temperature increase. However, IceBattery System has handled this situation very well.
We conducted the IceBattery System for 12 hours and after every 15 minutes, the lid of IceBattery Insulation Box was opened for 2-3 minutes. After 12 hours, we found that the temperature of IceBattery Box remained unchanged.
