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.

Questions about this item

Is this the correct capacity for my Yealink handset?

The pack is rated at 3.7 V and 900 mAh, which equals 3.33 Wh — the same capacity as the original W53-BATT and YLLP463346C800CLS cells.

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.

Does it use the standard Yealink connector?

Yes, it fits the W53, W53h, W53P, W73, W73H and W73P handsets directly, matching the original W53-BATT and YLLP463346C800CLS pin-out.
