Compatible Yealink handsets

This replacement battery fits Yealink W53, W53h, W53P, W73, W73H and W73P cordless handsets. It replaces original part numbers W53-BATT, YLLP463346C800CLS and YLLP523446C1010CTM. Office users and installers can swap the pack without tools. The pack arrives new and ready for immediate installation.

Lithium-ion voltage and capacity limits

The cell delivers a nominal 3.7 V and a rated capacity of 900 mAh, equating to 3.33 Wh. Lithium-ion chemistry performs best when kept between twenty and eighty percent charge. Deep discharge or continuous float charging will reduce the number of usable cycles over time.

Talk-time headroom and recharge point

A 900 mAh pack typically powers several hours of active calls and multiple days on standby before a recharge is required. Heavy users running back-to-back conversations will reach the low-battery warning sooner and should keep a charger nearby. Light desk use stays comfortably within a single daily charge cycle.

How long will a full charge last in daily use?

At 900 mAh the battery supplies roughly the same talk and standby time as the factory cell; actual hours depend on call volume, backlight and DECT signal strength.
