About this replacement
Razer Turret Gaming Lapboard — 3.7V Li-Polymer Replacement Battery (PL325385)
This 3.7V, 2150mAh Li-Polymer battery replaces the internal cell in the Razer Turret Gaming Lapboard. It fits the RZ03-0133 and RZ84-01330100 variants of the Turret — the wireless keyboard and mouse combo unit built for couch gaming on console or PC. Swap it in when the original cell no longer holds a charge or fails to power the board at all.
- Turret platform fit (RZ03-0133 / RZ84-01330100): Both Turret variants share the same internal battery bay and BMS communication protocol. The PL325385 cell matches the connector pinout and voltage rail these boards expect — no BMS rejection on either variant.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the Turret platform. The BMS accepted the cell at first connection, completed a full charge cycle without fault flags, and maintained stable output across both the keyboard and mouse subsystems simultaneously.
- RGB polling draw on the Turret: The Turret runs active RGB lighting alongside dual wireless polling for both the keyboard and mouse. Keep RGB profiles set to static or off when the board is below 20% charge — dynamic lighting effects draw extra current and can trigger the BMS low-voltage cutoff earlier than expected.
Why the Turret mouse stops tracking after a battery swap
The Turret houses both the keyboard and mouse on one shared power circuit fed by this single cell. After a full battery discharge or cell swap, the mouse subsystem can lose its pairing state even if the keyboard appears to reconnect normally. This happens because the mouse controller stores its connection data in volatile memory that clears on total power loss. Hold the pairing button on the underside of the mouse module for five seconds after reinstalling the battery to force a fresh handshake with the console or PC receiver.
Keyboard inputs dropping out while mouse still responds
When the cell voltage sags below roughly 3.5V under load, the Turret's power management prioritises the mouse polling channel over the keyboard matrix. The result is dropped or repeated keystrokes while the pointer still moves normally — it looks like a firmware bug but it is a voltage issue. Plug in the charging cable and check whether the dropouts stop immediately. If they do, the cell is at end of life and needs replacement rather than a recharge.
