The independent official model-family support table also states AA, but does not justify silently discarding the contradictory FAQ. · The original UK package/dimension tables and Logitech Support specification name AA cells; the exact UK page’s rechargeable FAQ names AAA cells. Both describe two included, replaceable batteries. Do not infer AA or AAA compatibility from the unresolved disagreement.
