Compatible Replacement Battery

This 3.7V lithium cell replaces the original battery in Logitech MX Anywhere 3, MX Master, MX Master 3 and MX Anywhere 2 mice. It matches the listed part numbers including 533-000172, 533-000121, AHB303450 and JT-04. The pack contains one battery certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards.

Capacity And Protection

Rated at 500mAh with a nominal 1.67Wh energy rating, the cell powers the mouse through normal daily use. Integrated circuitry guards against overcharge, over-discharge, over-voltage and short-circuit conditions to extend service life. The physical dimensions are 36.84 x 25.2 x 5.6mm and the weight is 35.0g.

Deciding Specification

The critical figure is the 500mAh capacity at 3.7V; if your original battery shows a different capacity or voltage this cell will not be a direct drop-in replacement. Buyers who need a higher capacity pack or a different form factor should look elsewhere.

Questions about this item

Will the 3.7 V 500 mAh Estry battery fit inside my existing MX Anywhere 3 without modification?

The cell measures 36.84 × 25.2 × 5.6 mm and weighs 35.0 g, matching the original dimensions so it slides into the same compartment.

How can I verify the replacement is working correctly after I install it?

The mouse should power on immediately, show normal cursor response and report a full charge in Logitech Options software.

Does the single pack include any tools or adhesive strips for the swap?

Only the battery cell is supplied; opening tools and any required adhesive must be sourced separately.
