  • 1500 mAh capacity keeps the keyboard running longer

Compatible Replacement Battery for Logitech MX KEYS

This lithium-polymer pack replaces the original YR0073 cell in Logitech MX KEYS keyboards. It delivers 3.7 V and 1.5 Ah capacity for extended wireless typing sessions. The black unit matches the original form factor and is supplied brand new with 100 % OEM compatibility.

Straightforward Swap With Minimal Risk

Installation requires opening the keyboard base and disconnecting the old pack before fitting the new one. The connector and 85.10 x 19.20 x 7.20 mm dimensions align with the factory layout, so no soldering or modification is needed. The main issue is damaging the fragile ribbon cables during disassembly if excessive force is applied.

Verify Your Keyboard Model and Part Number First

Confirm the device is a Logitech MX KEYS carrying the YR0073 designation and that the original battery bears part number 533-000177. Other Logitech keyboards use different cells and will not accept this pack. No other compatibility checks are required before ordering.
