Up to 19% off
New arrival
From $84.99 USD $104.99
Shipping calculated at checkout.
Fits Acer Aspire 3050 and AS36802682 models; replaces LC.BTP01.006, BT.00603.006, BT.00604.001, and related part numbers.
11.1V at 6600mAh delivers 73.26Wh — matches the original pack output for full portable runtime on this chassis.
Connector slides straight in with the locking tab oriented toward the release lever; no force needed on insertion.
We cycled this cell on the Aspire 3050 platform; BMS handshake completed on first charge with no fault codes or cutoff anomalies.
After installation, run a full discharge down to sleep mode, then charge uninterrupted to 100% — this resets the BIOS fuel gauge IC against the new cell and clears false low-health warnings that appear after every swap.

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.

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.

Laptop cuts off at 20–30% remaining shown on screen

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.

Frequently Asked Questions

The system info shows the wrong Wh rating after I put this battery in — is the cell actually undersized?

No — the Wh figure in system info pulls from the EEPROM on the fuel gauge IC, and a new cell ships with factory register values that don't always match the rated 73.26Wh. The OS is reading stored data, not measuring the actual cell. Run one full discharge to hibernate cutoff followed by a complete uninterrupted charge to 100%, and the fuel gauge IC will rewrite those registers with accurate values from the real cell chemistry.

The battery charges fine but the OS fuel gauge jumps around wildly for the first few days — percentage skips from 60% to 40% with no warning.

The fuel gauge IC on these Aspire cells needs several full discharge-and-charge cycles to map its internal discharge curve against the new cell's actual capacity. Until that calibration happens, the percentage readings are based on rough estimates and will spike or drop unexpectedly under load changes. Run two to three complete cycles — full discharge to automatic hibernate, then charge to 100% without unplugging early. After the third cycle the gauge stabilises and the erratic jumps stop.

My Acer laptop won't charge above 80% even with a brand-new battery installed — is something wrong with the cell?

The cell itself is not at fault. Many Acer BIOS versions include a charge limit feature — sometimes labelled "Battery Health Manager" or similar — that caps charging at 80% to extend cell lifespan over time. Check the BIOS setup screen (press F2 at boot) and look under the Power or Battery menu for a charge threshold setting. Set it to 100% or "Maximum Capacity" mode, save, and reboot — the battery will then charge fully to 11.1V.
