Description
The Poly CS540 Spare Rechargeable Battery (85Q98AA, part 86180-01) is the genuine Li-ion replacement battery for the CS540 DECT wireless headset, delivering up to 7 hours of talk time per charge. Having a spare battery charged and ready in the Savi/CS charging base means agents can swap to a fresh battery in seconds rather than waiting through a charge cycle — essential for contact centers running back-to-back shifts or users who regularly exceed a single battery's charge duration in a day.
Key Features
- Up to 7 Hours Talk Time: Full shift coverage from a single charge for most contact center workdays.
- Li-ion Chemistry: Rechargeable lithium-ion cell with 140mAh capacity — the correct replacement for the CS540.
- Shift-Change Ready: Charge spare in the 5-unit charging base (85R88AA) so agents always have a fresh battery at the start of their shift.
- Genuine Poly Battery: Manufacturer-sourced cell ensures correct voltage, capacity, and safe operation in the CS540.
