Compatible headset battery

The HP 784P8AA is a rechargeable battery kit manufactured for Poly headsets. It uses a proprietary form factor that matches the original equipment specification. The pack is supplied new and ready for immediate installation.

Replaces the original cell

Swapping the depleted pack with this unit restores full talk and standby time without soldering or adapter cables. Because the chemistry is rechargeable, the headset can be returned to service repeatedly instead of being discarded. The proprietary size ensures the battery seats correctly in the charging cradle.

Verify the headset model

Confirm that the headset you own accepts the 784P8AA part number before ordering. The proprietary dimensions mean the pack will not fit other Poly or third-party models. No charger or tools are included in the kit.

Questions about this item

When will the proprietary-size battery in the 784P8AA kit need replacing?

The rechargeable cell is rated for multiple charge cycles; replace it once talk time drops noticeably below a full shift.

What limit appears first during an all-day headset session?

Battery capacity is the first constraint — when the charge runs low the headset powers down until recharged.

Does the 784P8AA battery get warm or noisy during continuous use?

The sealed pack runs silently and stays at ambient temperature; no fan or active cooling is involved.
