About this replacement
Toshiba Satellite Click 2 L35W-B3204 — 11.1V Li-ion Replacement Battery (PA5187U-1BRS)
This is an 11.1V, 3700mAh (41.07Wh) Li-ion replacement battery for the Toshiba Satellite Click 2 L35W-B3204 hybrid laptop-tablet. It fits the detachable-screen L35W line, where the battery sits in the keyboard base unit. OEM part numbers PA5187U-1BRS and P000602680 both cross-reference to this cell.
- L35W keyboard-base compatibility: The Satellite Click 2 L35W series shares a single battery format across the L35W-B3204 and L35W variants — same voltage rail, same connector pinout, and the same BMS handshake the base unit expects before it will pass charge to the tablet display panel.
- Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the L35W platform. The BMS communicated correctly with the host, charge acceptance was normal across the full voltage range, and no fault codes appeared at the BIOS level during testing.
- Post-install calibration on the Click 2: After fitting this battery, run the device down to hibernate cutoff under normal use — detached or docked — then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that typically appears after any cell swap on this platform.
BIOS reporting poor battery health immediately after replacement on the L35W
The Satellite Click 2 stores charge history and health data in the old cell's EEPROM. When a new cell goes in, the BIOS compares live readings against that stale data and flags a mismatch as poor health. The battery itself is not faulty. One full discharge-to-hibernate followed by an uninterrupted full charge is the reset sequence the BIOS needs to re-anchor its health calculation to the new cell.
Click 2 shuts down at 20–30% battery remaining after the swap
This is a voltage cliff issue, not a capacity issue. Under combined CPU and display load — especially when the tablet panel is drawing power through the base — cell voltage can drop sharply before the fuel gauge reaches zero. The fuel gauge IC has not yet mapped the new cell's discharge curve, so it misjudges the remaining charge at high draw. Run two to three full discharge and recharge cycles to give the fuel gauge IC enough data to track the new cell accurately. After calibration, the cutoff point should move back below 5%.
