Exact replacement for Logitech T650 and MX Master

This lithium-polymer battery matches the original HB303450 specifications for the Logitech Touchpad T650 and MX Master mouse. It delivers 3.7V and 500mAh capacity in a 51.32 x 33.43 x 3.18mm form factor. The 37.0g cell includes overcharge, over-discharge, over-voltage and short-circuit protection. Certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards.

500mAh capacity for typical daily use

The 1.85Wh cell provides enough energy for regular desktop sessions with the supported Logitech devices. Runtime scales with usage intensity; heavy continuous tracking will deplete the charge faster than intermittent office work. When the battery no longer holds a useful charge, it must be replaced rather than repaired.

3.7V 51.32 x 33.43 x 3.18mm Li-Polymer cell

The single decisive specification is the physical and electrical match to part numbers HB303450, 533-000088 and 1506. Only devices designed for this exact voltage, capacity and 3.18mm thickness will accept the battery safely. Buyers with other Logitech models or third-party peripherals cannot use this cell.

Yes, it matches the original HB303450 dimensions of 51.32 x 33.43 x 3.18 mm and weighs 37.0 g, so it seats in the existing compartment.

How can I verify the replacement battery is functioning correctly after installation?

The Touchpad T650 or MX Master will recognise the 1.85 Wh cell, charge to full, and show normal battery-level reporting in the OS.

What comes in the package and is any extra hardware required?

Only the certified replacement cell is supplied; no screws, tools or cables are included, and none are needed for the swap.
