AXS equipped bikes should be stored with the batteries removed from the derailleurs with the protective covers installed to prevent damage to the battery latch and contacts.
AXS derailleur batteries should be removed from the derailleur and stored with a full charge and with the protective terminal covers installed. The protective covers should also be installed onto the derailleurs when the batteries are removed to prevent damage to the battery latch and contacts. Storing AXS derailleur batteries partially or fully discharged for extended periods of time can degrade their capacity and is not recommended. The CR2032 batteries located in AXS controllers can remain installed during times of storage. They will not discharge or corrode.
After Storage Use: as AXS derailleur batteries are stored they may discharge slightly. This is normal. When it comes time to start riding again, place the batteries back onto the charger to ensure they are fully charged before re-installation and use.
