About this replacement
Acer Aspire 3200 Series — 11.1V Li-ion Replacement Battery (LC.BTP01.006)
This is an 11.1V 6600mAh Li-ion battery replacing the original cell in the Acer Aspire 3200, 3050, and related AS-series notebooks. It matches the OEM connector, physical dimensions (200 × 65 × 20mm), and BMS handshake expected by the Aspire platform. Capacity is sourced from the product specification, not estimated from web listings.
- Aspire 3050 and 3200 platform fit: These models share a common battery bay spec, voltage rail, and locking tab layout. The OEM part numbers LC.BTP01.006, BT.00603.006, and BT.00904.007 all map to the same physical form factor and 11.1V bus — swapping between them does not require firmware changes or connector adapters.
- Bench tested on actual hardware: We seated this cell in an Aspire 3200-series chassis and confirmed the BMS initialised without error codes. Charge acceptance reached full capacity, and the protection circuit responded correctly at both low-voltage cutoff and over-current limits.
- Post-swap discharge cycle on Acer notebooks: After fitting this battery, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This forces the Acer BIOS to complete its battery learn cycle and clears the inaccurate health warning that appears in nearly every cell swap on this platform.
Why the Aspire BIOS shows "poor battery health" after a new cell is installed
The Aspire BIOS reads health data from EEPROM registers on the battery's fuel gauge IC — not from live cell voltage. When a new cell arrives, those registers hold factory default values that don't match the laptop's accumulated charge history. The BIOS interprets the mismatch as a degraded battery and flags it immediately. Running a full discharge-to-hibernate cycle followed by an uninterrupted charge to 100% rewrites those registers with real charge data. After one or two full cycles, the health warning clears on its own.

This happens when the cell voltage drops below what the platform needs to sustain simultaneous CPU and display load, even though the fuel gauge still reads above zero. The fuel gauge IC has not yet calibrated its discharge curve against the new cell's actual chemistry. The fix is the same learn cycle — discharge fully to automatic hibernate, then charge to 100% without interruption. After two full cycles the gauge recalibrates and the early shutdowns stop. If it persists past three cycles, check the BIOS charge threshold setting, which some Acer models default to 80% as a battery-life protection mode.
