Batteries4 × AAA
Replace the complete set together and follow the polarity marks in the battery compartment. Confirm the exact remote before ordering.

Optional upgrade: check the remote manual permits rechargeable batteries first. Battery size alone does not confirm compatibility. Buy a complete matching set for the quantity shown above.
NiMH batteries + charger
Traditional rechargeable cells use a separate NiMH charger and typically output 1.2 V. Check the remote supports this voltage; some remotes may report low battery earlier.
Manufacturer information ↗Batteries with a built-in USB-C charging port
Choose regulated 1.5 V AA/AAA cells with a USB-C port on each battery. Remove them from the remote to charge. These are different from a charger that merely has USB-C input. Never substitute a bare 3.7 V lithium cell or charge these in a NiMH charger.

Harmony 550
For an existing configuration, use Devices to test the receiver directly. If individual commands work but an Activity misses an input or power command, clear the infrared path and answer the remote’s Help questions while pointing at the equipment. The historical manual describes these controls; its online setup instructions do not establish that the retired service works today. Preserve working settings.
