It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Logitech G900 / G903 Series — 3.7V Li-Polymer Replacement Battery (533-000130)

This is a 3.7V 1000mAh lithium-polymer battery for the Logitech G900, G403, G703, and G903 wireless gaming mice. It replaces OEM part number 533-000130. When the original cell loses charge capacity, this swap restores the mouse to full operating condition without replacing the whole unit.

  • G900 / G403 / G703 / G903 compatibility: These four mice share the same battery bay dimensions and the same 3.7V single-cell Li-Polymer configuration. The connector pinout and BMS communication protocol are identical across the group, so one cell fits all four.
  • Bench tested on actual hardware: We ran this cell on a G903 and confirmed the BMS accepted the full charge cycle without tripping an over-voltage flag. The mouse reported a full battery state in Logitech G HUB immediately after installation.
  • RGB and polling load management: The G900 series runs its wireless receiver at 1ms polling. If you game with onboard RGB lighting active, the draw is meaningfully higher than with lighting off. Turning RGB off when not needed slows cell degradation over the battery's lifetime.

Why the G900 drops its wireless connection mid-session at low battery

The G900 runs a 2.4GHz LIGHTSPEED receiver that requires a stable voltage to maintain its 1ms report rate. As the Li-Polymer cell ages and internal resistance rises, voltage sags under the RF transmitter's burst draw. The mouse firmware interprets this sag as a low-power condition and throttles or drops the wireless link before the battery indicator shows critical. Replacing the cell eliminates the sag because a fresh cell holds a flat voltage curve under load.

Mouse pointer stuttering or jumping after a battery swap

If the pointer stutters immediately after fitting a new battery, the USB receiver has likely lost its pairing state due to the power interruption during the swap. Unplug the LIGHTSPEED receiver, wait ten seconds, then plug it back in. If that does not resolve it, hold the mouse's power button for six seconds to force a full BLE/LIGHTSPEED re-handshake. The mouse should reconnect and track smoothly once the receiver re-establishes at full 2.4GHz signal.

Frequently Asked Questions

My G900 won't reconnect to the USB receiver after I put the new battery in — what do I do?

The power gap during the swap breaks the LIGHTSPEED handshake. Unplug the receiver from your USB port, wait ten seconds, then plug it back in. If the mouse still shows no connection, hold the power button on the mouse for six seconds to trigger a forced re-pair. The connection should restore without any software steps.

The G903 pointer lags and skips when the battery meter drops below half — is the battery faulty?

This is not a faulty cell — it is normal end-of-life behaviour in the original battery. As internal resistance rises in an aged Li-Polymer cell, voltage sags under the RF transmitter's burst draw and the 1ms polling rate becomes unstable. A fresh 533-000130 cell holds a flat discharge curve under that load, which stops the lag. Check the voltage recovery: a healthy cell should read at or above 3.6V under light load immediately after charging.

Battery life on my G703 is noticeably shorter than it was when the mouse was new, even with the replacement cell — what causes that?

The G703 with onboard RGB lighting and 1ms polling draws significantly more than a standard office mouse. If G HUB has RGB set to full brightness on a multi-zone profile, discharge will be faster than the rated capacity suggests. Drop lighting to a single static low-brightness colour or disable it entirely and retest. You should see a clear improvement in charge duration without any hardware changes.
