Logitech G Pro 533-000151 Compatible Battery 3.7V 220mAh

Logitech G Pro / PRO X Superlight — 3.7V Li-Polymer Replacement Battery (533-000151)

This 3.7V, 220mAh lithium-polymer cell replaces the internal battery in the Logitech G Pro, Pro Wireless, PRO X Superlight, and M-R0070 wireless gaming mice. It matches OEM part numbers 533-000151, AHB521630PJT-04, 533-000208, and 533-000211. The cell measures 31.90 × 16.50 × 5.50mm — confirm your original dimensions before fitting.

• G Pro / PRO X Superlight platform fit: These mice share the same internal battery bay dimensions, connector pinout, and BMS handshake protocol across the G Pro, Pro Wireless, and PRO X Superlight lines. A single cell covers the full range because Logitech kept the power architecture consistent across generations.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a G Pro Wireless unit. The BMS accepted the cell without fault flags, voltage settled at 3.7V nominal, and the mouse reported a full charge state through the LIGHTSPEED receiver software.
• Post-swap connector seating: The ZH 1.5mm JST-style connector on these mice sits flush against the PCB recess. Press it in squarely — a crooked seat causes intermittent power loss that looks like a faulty cell but is a contact issue.

Why the PRO X Superlight drops to low battery faster after a cell swap

The LIGHTSPEED wireless chipset in the PRO X Superlight runs a 1000Hz polling rate by default — significantly higher than standard office mice. That polling rate is constant regardless of movement, so the draw never fully idles. A 220mAh cell at this duty cycle depletes noticeably faster than users expect coming from a phone or keyboard battery. G HUB software shows battery percentage in real time; watch the discharge curve over the first two full cycles to confirm the cell is behaving correctly rather than assuming it is defective.

Mouse pointer stuttering or cutting out before battery indicator reaches zero

The LIGHTSPEED receiver starts reducing the polling rate when cell voltage drops below approximately 3.2V to protect the wireless link — this shows up as stutter or lag before the mouse fully shuts off. If stuttering begins earlier than expected after a cell swap, the new battery may not have completed its first full charge cycle. Charge via the USB-C cable until the indicator in G HUB reads 100%, then discharge fully once before judging performance. If stutter persists at a full charge state, reseat the connector and check the voltage at the cell terminals — it should read at least 3.6V at rest.
