Up to 21% off
New arrival
From $24.99 USD $30.99
Shipping calculated at checkout.
Fits Razer Turret Gaming Lapboard model RZ03-0133 and RZ84-01330100, replacing OEM part PL325385.
3.7V, 2150mAh Li-Polymer cell delivers the voltage and capacity needed to power both wireless keyboard and mouse modules without voltage sag during gaming sessions.
Single internal connector with fixed orientation; slides into the battery compartment beneath the lapboard with positive terminal facing the contact pin.
We bench-tested this cell in the Turret receiver circuit and confirmed stable BMS output through full charge and 80% depth-of-discharge cycles without early cutoff.
On first install, hold the pairing button for three seconds after insertion — the Turret wireless receiver sometimes requires re-sync after prolonged power loss to restore both input channels.

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.

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.

Frequently Asked Questions

My Turret mouse won't reconnect to my console after I swapped the battery — keyboard is fine though. What's wrong?

Total power loss during a battery swap clears the mouse controller's pairing memory, even when the keyboard recovers on its own. The two subsystems store connection data independently. Hold the pairing button on the underside of the Turret mouse module for five seconds with the new battery installed — this forces the mouse to re-establish its link with the receiver rather than look for a session that no longer exists.

The mouse pointer stutters and skips even with a new battery installed — what causes that?

Pointer stuttering on a freshly installed cell usually means the battery isn't making firm contact with the connector, not a fault with the cell itself. Check that the connector is fully seated and the battery is flush in the bay with no flex. If contact is solid and stuttering persists only when RGB lighting is active, the lighting profile is pulling enough current to cause brief voltage dips — switch to a static colour or disable RGB until the cell completes its first full charge cycle and the BMS calibrates.

The Turret charges to full but the battery drains far faster than it used to — is 2150mAh correct for this board?

Yes, 2150mAh at 3.7V is the correct rated capacity for the PL325385 cell in this board. Faster-than-expected drain usually comes from the Turret running dynamic RGB effects and dual wireless polling simultaneously — that combination draws significantly more than the keyboard or mouse would consume individually. Disable dynamic lighting effects in Razer Synapse and check whether drain rate normalises. If capacity still drops sharply within a short session, the replacement cell may not have reached its stable capacity — run two full charge cycles before concluding there is a fault.
