Rapoo VT950 ICR14500 Replacement Battery 3.7V 1000mAh

Rapoo VT950 — 3.7V Li-ion Replacement Battery (ICR14500)

This 3.7V 1000mAh Li-ion cell replaces the internal battery in the Rapoo VT950 wireless gaming mouse. It uses an ICR14500 form factor — 14500 being the standardised cylindrical size (14mm diameter, 50mm length) used in a number of compact wireless peripherals. When the original cell degrades and the mouse stops holding charge, this is the direct swap.

• VT950 platform fit: The VT950 uses a single ICR14500 cell running at 3.7V nominal. The mouse's internal power circuit is sized for this voltage rail — substituting a different cell format or chemistry will cause charging faults or no-power conditions.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a controlled rig. The BMS protection circuit tripped correctly at low-voltage cutoff, and the cell accepted a full charge without thermal deviation.
• Connector orientation on the VT950: When seating the replacement cell, confirm the polarity markings on the battery tray before pressing the cell into contact. The VT950's tray does not have a mechanical keying block — reversing polarity will blow the protection circuit on the first connection.

Mouse pointer stuttering in the last 20% of battery charge

Wireless gaming mice reduce their USB or 2.4GHz polling rate automatically as cell voltage drops below roughly 3.5V. The VT950 shows this as erratic or sluggish cursor movement before the battery fully dies. This is the power management firmware doing its job — it is not a sensor fault. Fitting a fresh cell and charging to full (4.2V) clears the symptom immediately.

VT950 not reconnecting to USB receiver after battery swap

A complete power loss — such as a flat or removed battery — can drop the handshake between the VT950 and its nano receiver. The receiver retains the pairing in firmware, but the mouse sometimes needs to re-announce itself. Unplug the USB receiver, hold the connect button on the underside of the mouse for three seconds, then reinsert the receiver. The mouse should reconnect within five seconds.
