Battery, Charging and Operating

  • How long does the battery last?

    The battery packs inside the Cellbox®; provide an uninterrupted power source for the operation of the Cellbox®; during transport for more than 24 hours (at a preset temperature of 37°C when ambient temperature is 23°C).

  • How can I charge the box?

    The Cellbox®; is fitted with 4 lithium-ion battery packs (99,4Wh each), that can be charged from any wall socket that provides 100-230 V.

  • How long does it take to fully charge the box?

    Nine hours will be required to fully charge the batteries.

  • How can I charge the box during transport?

    It is essential that the battery packs of the Cellbox®; are fully charged before the transport of any goods. To extend battery life during transport, confirm that the car adapter is set to 24V DC and connect it to the auxiliary car power outlet.

  • Why do the green lights blink?

    Each of the LEDs represent a 25% charge value. A blinking LED therefore indicates that the Cellbox®; is either being charged or discharged. When all four of the LEDs are steadily lit in green, the Cellbox®; is fully charged (100%). Three green-lit LEDs indicate a battery level of 75%, two of 50% and so on.

  • Can I use the Cellbox® ground CD in the plane?

    Due to International Air Transport Association regulations, it is strictly forbidden to transport an operating Cellbox®; ground CD in any aircraft. If you want to ship your cells by air, have a look at our Cellbox®; flight CDI.

  • Which dangerous goods regulations apply?

    Because the Cellbox®; contains lithium-ion-batterys, UN3481 applies and needs to be indicated on the outside of the box. Additionally, the Cellbox®; Flight CDI needs a dry-ice indication: UN1845 Dry-Ice label. Please add amount of dry ice in kilograms as well as shipper’s and consignee’s information.

  • How do I activate the Energy Saving Mode?

    For the general user the energy saving mode should be set to auto. If not, please have a look at the technical manual of your device.


  • How do I change the CO2 cartridge in the Cellbox Ground CD?

    To refill, open the Cellbox and gain access to the CO2 compartment by opening the circular lid to the right of the incubation chamber. Screw the disposable cartridge carefully onto the thread and replace the circular lid securely on top of the compartment. Removing the disposable cartridge may lead to rapid release of remaining CO2 which could cause a static charge as well as ice formation in and around the thread. Please wait for several minutes before reinstalling a new cartridge.

  • How do I change the dry-ice in the Cellbox flight CDI?

    Attention: Always handle dry ice with the appropriate personal protective equipment! Open the Cellbox and gain access to the dry-ice container by unscrewing the lid in an anti-clockwise motion. Use a small dry ice scoop or shovel to fill the container up to right below the thread for the lid. Replace the lid and tighten it in a clockwise manner.

  • How much dry-ice does the box need?

    The container is suitable for 460g of dry ice. Always ensure that the maximum amount of dry ice has been used without obstructing the lid from closing securely.

Cleaning, Storage and Service


  • What is displayed on the homescreen?
