Fits Acer Aspire 2002WLCi and replaces BATCL32, BATCL32L, BT.A1401.001, BT.A1405.001, BT.A2401.001, BTP-AS2000, LC.BTP05.001.
14.8V 4400mAh chemistry delivers 65.12Wh to sustain this Aspire through full-day portable use without AC power.
Connector slides straight into the battery slot with a single retention latch; orientation is keyed and cannot insert reversed.
We bench-tested this cell on the 2002WLCi and confirmed the BMS charged to 16.8V under load with stable voltage holds through discharge cycles.
After installation, run one full discharge cycle to hibernation cutoff then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell 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 2000 Series — 14.8V Li-ion Replacement Battery (BATCL32)

This is a 14.8V 4400mAh (65.12Wh) Li-ion battery for Acer Aspire 2000-series notebooks, including the 2002WLCi, 2026LMi, 2001LMi, and 2025LMi among others. It replaces OEM part numbers BATCL32, BATCL32L, BT.A1401.001, BT.A2401.001, BTP-AS2000, and LC.BTP05.001. Dimensions are 128.20 × 100.60 × 19.80mm — check yours before ordering if the bay has been modified.

  • Aspire 2000-series compatibility: These models share a common 14.8V four-cell architecture and the same battery bay connector pinout. The BMS handshake uses the same SMBus protocol across the range, so one cell fits the full group without firmware differences between SKUs.
  • Bench tested on actual hardware: We ran this cell on an Aspire 2002WLCi and cycled it through charge and full-load discharge. The BMS held cutoff voltage correctly at the low end, and charge termination triggered cleanly at 16.8V with no overcharge events recorded.
  • First-cycle calibration on the Aspire 2000: After installation, run one full discharge until the laptop hibernates on low battery, then charge uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the inaccurate health warning that almost always appears after a cell swap on this platform.

Why the Aspire 2002WLCi shuts down at 20–30% after a battery swap

The Aspire 2000's fuel gauge IC builds a discharge model from the original cell's EEPROM data. When a new cell goes in, that model is wrong — the IC thinks the voltage floor is higher than it actually is. At around 20–30% shown on the gauge, the real cell voltage drops below the IC's learned threshold under CPU and display load, and the system cuts power instantly. Running two full calibration cycles — full discharge to hibernate cutoff, then full uninterrupted charge — rewrites the model against the new cell's actual curve and eliminates the premature shutdown.

BIOS reports battery health as "poor" or "replace" immediately after install

This happens because the BIOS reads health data stored in the old cell's EEPROM, not from live measurements of the new cell. The new cell arrives with a neutral EEPROM state that the BIOS interprets as degraded. It is not a fault with the replacement. Complete one full discharge-to-hibernate followed by a full charge to 100% — after that cycle the BIOS recalculates health from actual charge data and the warning clears.

Frequently Asked Questions

My Aspire 2002WLCi shows the wrong Wh rating in system info after fitting the new battery — is the cell actually the right capacity?

The Wh figure shown in Windows or the BIOS comes from EEPROM data embedded in the battery, and the value stored at the factory sometimes differs slightly from the actual cell chemistry installed. The physical capacity of this cell is 65.12Wh at 4400mAh — that is what you are getting. Run one full calibration cycle (discharge to hibernate cutoff, then charge uninterrupted to 100%) and the system will recalculate from live data rather than the stored EEPROM value.

The fuel gauge on my Aspire jumps around wildly for the first few charges — shows 60%, then 90%, then drops to 40% with no pattern.

The fuel gauge IC on the Aspire 2000 platform calibrates itself against the cell it learned on. A new cell has a different internal resistance curve, so the IC's discharge model is mismatched for the first few cycles. This is normal and not a fault. Run two to three full discharge-to-hibernate and full-charge cycles back-to-back and the gauge will stabilise once the IC has mapped the new cell's actual voltage curve.

New battery installed, laptop plugged in, but charge stops at 80% and never goes higher — is the cell defective?

This is almost always a BIOS-controlled charge limit, not a fault with the cell. Acer's firmware on some 2000-series units activates a charge ceiling at 80% when the battery health data looks degraded — which it will on first install before calibration. Clear the health flag by running one full discharge to hibernate cutoff, then plug in and let it charge to 100% without unplugging. If the BIOS still caps at 80% after two calibration cycles, check Acer's power management settings in the BIOS under the battery care option and set it to maximum charge.
