Battery

AAA

1.5V alkaline cell

AAA is a smaller standard cylindrical cell. Streaming remotes and many calculators use AAA — check quantity and chemistry on your device page. Bose Smart Soundbar 900 / SoundTouch remotes are 2× AAA — not the CR2032 Bose remotes.

Device-specific caveats

From manufacturer-backed notes on devices that use AAA — not generic advice.

  • 2× AAA alkaline (not rechargeable per Logitech specs).
  • 2× AAA replaceable — not a sealed rechargeable MX Keys sibling.
  • Bluetooth pairing issues are separate from battery type — fit fresh AAA first, then re-pair if needed.
  • Do not use rechargeable AAA unless Bose later documents otherwise for your exact remote.
  • Identify Voice Remote by model (e.g. RCAL7R) — Voice Remote Pro is sealed rechargeable, not 2× AAA.
