Direct replacement for Toucad T650 MX Master

This Estry lithium battery pack matches the original HB303450 specifications for the Toucad T650 MX Master mouse. It delivers a 500mAh capacity at 3.7V with 1.85Wh energy rating. The single-cell unit weighs 37.0g and measures 51.55 x 34.8 x 3.6mm for a precise internal fit.

Low self-discharge chemistry with protection circuit

The lithium cell maintains stable voltage during typical wireless mouse workloads without noticeable heat buildup. Integrated overcharge, over-discharge, over-voltage and short-circuit protection prevents damage from charging anomalies. RoHS, CE, ISO9001, UN38.3 and MSDS certifications confirm compliance with safety and transport regulations.

Restores runtime when original cell degrades

Replaces a worn HB303450, 1506 or 533-000088 pack that no longer holds a full charge. The jump is worth it when the mouse shows reduced operating time between charges or unexpected shutdowns. Not suitable for devices requiring a different voltage, capacity or physical footprint.

Questions about this item

How do I install the Estry 500 mAh 3.7 V pack in my Toucad T650 MX Master, and what step is often missed?

Open the mouse, disconnect the old HB303450 cell, connect the new pack's JST lead to the same socket, and tuck the 51.55 x 34.8 x 3.6 mm unit into the cavity; the step people miss is reseating the connector fully so the 3.7 V rail makes solid contact.

What maintenance or replacement will this 1.85 Wh lithium cell need later?

The pack has built-in overcharge, over-discharge, over-voltage and short-circuit protection, so no routine maintenance is required; when run-time noticeably falls, replace it with another HB303450 / 1506 / 533-000088 compatible cell.

What limit appears first during sustained use of this 37 g replacement battery?

The 500 mAh capacity sets the runtime ceiling; under continuous load the cell will hit its voltage floor and trigger the protection circuit before thermal limits become an issue.
