CR2032 Lithium Coin Cell
The wireless controllers (shifters) depend on these cells to broadcast pairing signals to the rear derailleur. If the voltage drops below approximately 2.85V, the RF transceiver may lack the necessary peak current to complete the cryptographic handshake for pairing, leading to a 'lost' connection despite the hardware appearing functional. Replacing the cell restores the signal amplitude required for the master-client link.

SRAM AXS Battery
The rear derailleur acts as the system master; if its internal logic board detects a degraded cell or a high internal resistance in the Li-ion battery, it may disable the pairing radio to preserve critical shifting function. Swapping the battery ensures the system master has a stable 7.4V nominal supply to maintain the AIRE wireless network.

SRAM Rival eTap AXS Rear Derailleur
If the derailleur's integrated 2.4GHz antenna or the logic processor's non-volatile memory (NVM) fails, the unit will be unable to store or recognize new pairing IDs. This hardware-level failure is the only resolution if the unit fails to enter pairing mode (alternating green/red or rapid flashing) after verified power delivery from a known-good battery.
