The battery is the one part of a wireless headset that wears out predictably. After a few hundred charge cycles endurance drops far enough that the headset no longer lasts a working day, while the audio and range remain fine.

Replacing a battery is an order of magnitude cheaper than a new headset and it can be planned. For contact centres we recommend budgeting for it from the start, because otherwise it becomes an unplanned outage in the middle of a shift.

⚑ atlantis note

Two versions for the same model

For the CS540 we carry two batteries, 85Q98AA and 784Q3AA#ABB, the latter being the newer version for the European market. We will verify which belongs to a headset from its order code.

A battery is planned maintenance, not a warranty claim

The battery should be replaced after three years or 500 charge cycles. In a contact centre running all day that means the replacement falls due before the headset itself wears out. It belongs in the quote up front, not in a claim, where it is treated as wear.

How to tell it is time

The typical symptom is that the headset no longer lasts a shift even when fully charged in the morning. If endurance drops well below the manufacturer's figure, the battery is done and the headset is otherwise fine.

Frequently asked questions

How often is the battery replaced?

Replacement is recommended after three years or 500 charge cycles. In practice that works out at three years in all-day use and longer with occasional wear.

Can I tell when the battery is done?

Yes. The headset stops lasting a shift even when fully charged in the morning, while the audio and range still work. That is the typical symptom.

Can the user replace it themselves?

On some ranges the battery is replaced with a tool that comes in the pack. We are happy to verify the procedure for a specific model before you order.
