Dell Inspiron 1525 Replacement Battery 11.1V 8800mAh GP952

Dell Inspiron 1525 / 1526 / 1545 / 1546 — 11.1V Li-ion Replacement Battery (GP952)

This is an 11.1V Li-ion replacement battery rated at 8800mAh (97.68Wh) for the Dell Inspiron 1525, 1526, 1545, and 1546 notebook series. It replaces a wide range of Dell OEM part numbers including GP952, GW252, RU586, RN873, HP297, and TT485. Fit the original connector, seat the latch, and the BIOS will detect it immediately on boot.

• Inspiron 1525 / 1526 / 1545 / 1546 compatibility: These four models share the same 11.1V battery bay geometry, connector pinout, and BMS communication protocol. Dell used a common platform across this generation, so a single cell SKU covers all four without any adapter or modification.
• Bench tested on actual hardware: We ran this cell on an Inspiron 1525 and an Inspiron 1545. The BMS handshake completed on first boot, charge acceptance started within 30 seconds of connecting AC, and the fuel gauge IC tracked the charge curve without flagging an error state.
• BIOS learn cycle after installation: After fitting this cell, run the laptop on battery power until it hibernates at low-charge cutoff, then charge uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.

Why the Inspiron 1525 shuts down at 20–30% after a battery swap

The Dell BIOS on this platform stores discharge curve data from the previous cell. When a new cell goes in, the BIOS is still mapping voltage readings against the old cell's curve. At around 20–30% displayed charge, the new cell's actual voltage crosses below the BIOS's stored low-voltage threshold — so it triggers an emergency shutdown even though real capacity remains. One complete discharge-to-hibernate followed by a full uninterrupted charge resets this mapping. After two or three full cycles the fuel gauge IC recalibrates against the new cell and the early shutdowns stop.

BIOS reporting battery health as "poor" or "replace" immediately after fitting a new cell

The BIOS reads health status from EEPROM data embedded in the battery's BMS chip. On a fresh cell, that EEPROM contains factory-default values that the Dell firmware sometimes interprets as a degraded state rather than a new cell. This is a firmware-reading issue, not a fault with the cell itself. Boot into the Dell BIOS, navigate to the battery health screen, and confirm voltage reads between 11.1V and 12.5V at full charge — if it does, the cell is good and the health warning will clear after the first full learn cycle.
