Direct Replacement for Logitech MX Keys YR0073

This 1500mAh 3.7V lithium-polymer battery matches the original 533-000177 part number and MX KEYS keyboard model. It supplies 5.55Wh of energy and measures 85.1 x 19.2 x 7.2mm at 127.0g. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits.

Single-Cell Li-Polymer Chemistry Constraints

The pack delivers a fixed 3.7V nominal voltage and 1500mAh capacity; it cannot be fast-charged beyond the keyboard’s own controller limits. Capacity will gradually diminish with charge cycles and storage temperature extremes. The protection circuit interrupts output if voltage or current exceeds safe thresholds.

Verify Keyboard Model and Part Number First

Confirm your keyboard shows MX KEYS and the original battery label reads 533-000177 or YR0073 before ordering. The connector polarity and ribbon length must match the factory layout exactly. Installing a pack with different dimensions or pin-out will prevent proper seating and charging.
