Logitech G913 Replacement Battery 3.7V 1500mAh

Logitech G913 / G915 Series — 3.7V Li-Polymer Replacement Battery (533-000152)

This is a 3.7V, 1500mAh Li-Polymer battery for the Logitech G913, G913 TKL, G915, and G915 Lightspeed wireless keyboards. It replaces OEM part numbers 533-000152, 533-000204, and AHB355085PCT-02. When the original cell degrades and the keyboard stops holding charge between sessions, this is the direct swap.

• G913 and G915 platform fit: Both the full-size G913/G915 and the TKL variants run the same flat Li-Polymer cell at 3.7V with an identical connector and BMS handshake. One cell covers all four keyboard variants listed.
• Bench tested on actual hardware: We ran this cell in a G915 Lightspeed with RGB lighting active. The BMS accepted the cell without fault flags, charge acceptance was normal from depleted state, and the keyboard reported battery percentage correctly in Logitech G HUB software.
• RGB lighting draw management: The G913 and G915 series consume significantly more power with per-key RGB active at full brightness. If you want to extend time between charges after fitting this battery, reduce RGB brightness or set lighting to sleep on idle — the keyboard's own power profile handles this inside G HUB.

G915 Lightspeed pairing lost after battery swap

A full power loss — which happens when you pull the old cell before fitting the new one — can clear the keyboard's active pairing state. The G915 and G913 store Lightspeed pairing in onboard memory, but a hard power-off occasionally resets the active connection slot. After fitting this battery, if the keyboard does not reconnect automatically, hold the Lightspeed connection button on the back for three seconds with the USB receiver plugged into the same port as before. That re-establishes the link without needing to delete and re-pair from scratch.

G HUB showing incorrect battery percentage after replacement

G HUB reads battery state-of-charge from the BMS over the Lightspeed connection. Immediately after fitting a new cell, the firmware may report a stale or inaccurate percentage — sometimes 0%, sometimes a mid-range number that doesn't move. Charge the keyboard fully via USB-C until the charging LED goes solid, then disconnect and let G HUB poll for 60 seconds. The reported percentage recalibrates once the BMS has completed one full charge cycle and the firmware has updated its internal reference point. If the display still reads incorrectly after one full charge, check that firmware is current in G HUB under Device Settings.
