Logitech Squeezebox Radio Remote Compatible Battery 12V 2000mAh

Logitech Squeezebox Radio (533-000050) — 12V Ni-MH Replacement Battery

This is a 12V, 2000mAh Ni-MH battery for the Logitech Squeezebox Radio remote. It replaces OEM part 533-000050 and fits the XR0001 and X-R0001 remote handsets. When the original battery fades, the remote loses IR output before it loses power entirely — this swap restores full signal strength.

• Squeezebox Radio XR0001 and X-R0001 remotes: Both remote variants share the same 12V Ni-MH cell stack, connector format, and BMS handshake — one battery covers both. The 10-cell AA-format Ni-MH pack is a direct physical and electrical match for either model.
• Bench tested on actual hardware: We cycled this battery through charge and discharge on the Squeezebox remote platform. The BMS accepted the charge curve without fault flags, and IR output held at full strength across the discharge range.
• Multi-cell replacement tip: This is a 10-cell pack — replace it as a unit, not alongside the original. Running a partially depleted old pack in parallel with a new one causes the new cells to drain faster compensating for the weaker pack.

Why Ni-MH voltage sag kills IR output before the remote feels "dead"

Ni-MH cells under load drop voltage more sharply than alkaline as they age. The IR LED in the Squeezebox remote needs a consistent voltage threshold to fire at full power. Once the pack sags below that threshold under transmit load, the remote appears sluggish or short-range — even though a no-load voltage check might still read acceptable. Replacing the pack restores the sustained current the LED circuit needs.

Remote stops responding entirely after battery install

The most common cause is reversed polarity on the connector. The 10-cell pack has a keyed connector, but it can be seated incorrectly if forced. Check that the red wire aligns with the positive terminal marked inside the remote bay. If polarity is correct and the remote still shows no response, verify the pack is charged — Ni-MH ships partially discharged and needs a full charge cycle before use. A full charge brings the pack to approximately 14.4V open circuit.
