EVESKY 3.7V 2200mAh Replacement Battery for Logitech MX1000 M-RAG97

SKU CH-77A9-ZT5CX

Replacement lithium-polymer battery for Logitech MX1000 and M-RAG97 mice with 2200 mAh capacity and built-in protection

  • Higher 2200mAh capacity extends wireless mouse runtime
  • 500mAh more than original 1700mAh L-LB2 battery
  • Lighter 32g polymer cell versus 50g original for smoother control
  • Built-in protection module guards against over-charge, over-discharge and short circuit
  • Direct L-LB2 replacement fits MX1000 and M-RAG97 with plug-and-play install

Compatible mice

This 3.7V 2200mAh LiPo battery replaces the L-LB2 cell in Logitech MX1000 and M-RAG97 cordless mice. It installs without modification and works immediately after fitting. The pack includes a protection module against over-charge, over-discharge and short circuit. Buyers with other mouse models should verify the original battery wire order before ordering.

Sustained capacity gain

The 2200mAh capacity is 500mAh higher than the original 1700mAh L-LB2 battery, so the mouse runs longer between charges under the same workload. Polymer construction reduces cell weight from 50 grams to 32 grams, which can make the mouse feel lighter in hand. Full charge voltage reaches 4.2V and the protection circuit cuts off at 3.0V to prevent deep discharge. This is a single-cell replacement, not a multi-cell power bank.

Pre-installation checks

Confirm that your mouse uses the L-LB2 battery and that the connector wire sequence matches the replacement. If the plug pinout differs, the wires must be rearranged before connection. The protection module handles safety, but the host device must accept a 3.7V nominal LiPo cell with a 3.6V to 4.2V charge range. No charger or tools are included in the pack.
