Corsair RGP0106 Replacement Battery 3.7V 500mAh

Corsair Sabre Wireless Gaming Mouse — 3.7V Li-Polymer Replacement Battery (AHB682730)

This is a 3.7V, 500mAh Li-Polymer battery that fits the Corsair RGP0106 and Sabre Wireless Gaming Mouse. It replaces OEM part AHB682730 when the original cell has degraded or failed. Dimensions are 33.60 × 25.40 × 6.20mm — measure your existing cell before ordering to confirm fit.

• Sabre Wireless compatibility: The Sabre Wireless platform uses a single Li-Polymer cell at 3.7V nominal. The BMS in this mouse monitors cell voltage directly — swapping in a mismatched capacity or chemistry triggers low-battery shutdown faster than expected, so match the OEM spec exactly.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the Sabre Wireless platform. The BMS accepted the cell without error, held full charge at 4.2V, and cut off cleanly at the low-voltage threshold without false triggers.
• Post-swap power-on check: After seating the new battery, hold the mouse power button for three seconds rather than a quick press. The Sabre Wireless firmware requires a sustained power-on signal after full power loss — a short press registers nothing and the mouse appears dead.

Keyboard pairing lost after battery swap on Corsair wireless peripherals

Corsair wireless keyboards paired via Slipstream or Bluetooth lose their pairing state when the battery drops to zero and the BMS disconnects the cell entirely. This is not a fault with the new battery — it is a firmware behaviour triggered by full power loss. After fitting the replacement, hold the pairing button on the underside of the keyboard until the LED flashes rapidly, then re-pair through the USB receiver or your OS Bluetooth menu. The reconnection completes within 30 seconds under normal conditions.

Mouse pointer stuttering or lagging before the low-battery indicator appears

The Sabre Wireless reduces its Bluetooth or Slipstream polling rate automatically when cell voltage drops below approximately 3.5V — this happens before the on-screen battery warning triggers. The result is visible pointer lag or jitter that looks like a tracking fault but is actually a power-saving response. Charging the mouse or fitting a fresh cell resolves it immediately. If stuttering returns within a short charge cycle, the cell has lost capacity and needs replacement.
