Direct replacement for MX KEYS

The Estry YR0073 is a lithium-ion battery built to match the original specifications for the MX KEYS keyboard. It delivers a capacity of 1500mAh at 3.7V for reliable wireless operation. The pack includes a single cell measuring 85.1 x 19.2 x 7.2mm and weighing 77.0g. It is certified under ISO9001, RoHS, CE, UN38.3 and MSDS.

Consistent output through the discharge cycle

Built-in protection circuits guard against overcharge, over-discharge, over-voltage and short-circuit events during extended use. This design helps the cell maintain stable voltage as capacity depletes, avoiding sudden drops that could interrupt typing sessions. Each unit undergoes strict specification detection and use testing before shipment to verify safe and durable performance over time.

Limited to devices using the 533-000177 part

This battery only fits hardware that accepts the exact 533-000177 form factor and connector layout. It will not work with keyboards or other devices that require a different pin arrangement, voltage level or physical dimensions. Buyers needing a higher capacity cell or a different voltage must look for a pack specifically engineered for their model.

Questions about this item

How much heat does the 3.7V 1500mAh pack generate during all-day use?

The lithium cell includes overcharge, over-discharge, over-voltage and short-circuit protection, which keeps temperatures stable under normal daily loads.

What must I already own for this YR0073 replacement to work?

You need a Logitech MX KEYS keyboard that accepts part number 533-000177; the pack is a direct drop-in for that model.

Will the 85.1 x 19.2 x 7.2 mm pack fit alongside the original MX KEYS charging circuit?

Yes, it matches the factory dimensions and 3.7V specification, so the existing charging board recognises and manages it normally.
