Centenex DS-CS-SRF860SL replacement battery

This Centenex Electronics DS-CS-SRF860SL is a 2.4V 700mAh Ni-MH battery designed for specific Sony wireless headphones. It replaces the original BP-HP550-11 pack in models such as the MDR-RF860, MDR-RF925 and MDR-RF810 series. The black cell delivers 1.68Wh capacity for cordless listening. It suits owners of compatible Sony headsets needing a fresh power source.

Upgrade from a depleted original pack

The battery replaces a worn-out BP-HP550-11 when the original no longer holds a useful charge. The jump is worth it when runtime has dropped below practical listening sessions or the headset cuts out unexpectedly. It restores the factory voltage and chemistry without modification. Users whose headphones still meet their audio needs but lack stamina benefit most.

Simple two-wire swap with polarity care

Installation requires opening the headphone battery compartment and disconnecting the old pack before connecting the new one. The 46.00 x 23.00 x 11.00 mm dimensions match the original cavity. The main risk is reversing the connector polarity, which can damage the headset electronics. Verify the wire colours against the original before soldering or clipping. Charge fully before first use.
