Battery Care Tips
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
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.

Averatec 2100 Series — 14.4V Li-ion Replacement Battery (0299-MP1006J443)
This 14.4V, 4400mAh (63.36Wh) Li-ion battery replaces worn cells in the Averatec 2100, 2150, 2155, and AV2155EH1 notebooks. It fits the same connector and battery bay as the original pack. Voltage and capacity match the OEM spec exactly.
- 2100 and 2150 series compatibility: These models share the same 14.4V rail, physical bay dimensions, and connector pinout — that is why one cell crosses all of them. The BMS handshake protocol is identical across the series, so the BIOS reads this pack without modification.
- Bench tested on actual hardware: We ran this pack through charge and discharge cycles on a 2100 chassis. The BMS held charge termination correctly at 4.2V per cell, and the protection circuit tripped cleanly on overcurrent — no anomalies logged.
- First-cycle reset for the 2100 BIOS: After installing, run one full discharge down to hibernate cutoff, then charge uninterrupted to 100% without unplugging early. This lets the BIOS complete its battery learn cycle and clears the inaccurate health warning that appears after every cell swap.
Why the Averatec 2100 BIOS flags a new battery as poor health
The BIOS reads health data from EEPROM registers written to the original cell during manufacturing. A replacement cell ships with different EEPROM baseline values, so the health estimate looks wrong on first boot — sometimes showing 0% or "unknown." This is a data mismatch, not a faulty battery. One complete discharge-to-hibernate followed by a full uninterrupted charge resets the learn cycle and re-anchors the health estimate to the new cell's actual capacity.
Averatec 2100 shutting down suddenly at 20–30% charge shown
The fuel gauge IC calculates remaining charge based on a model built against the old cell's characteristics. After a swap, that model is stale — the new cell hits a voltage cliff under full CPU and display load before the gauge reaches zero. The laptop interprets the sudden voltage drop as an emergency and cuts power. Two to three full calibration cycles — discharge fully to hibernate, charge to 100% each time — re-train the gauge IC against the new cell. After calibration, the shutdown threshold should align with actual cell voltage near 3.0V per cell.

Frequently Asked Questions
The Averatec 2100 BIOS is showing the wrong Wh rating after I swapped the battery — is the new pack actually the right size?
The Wh figure the BIOS reports comes from EEPROM data stored on the battery's controller chip, not from measuring the actual cells. The replacement cell's EEPROM ships with values that may differ slightly from what the original pack reported — this is a data label difference, not a capacity difference. The physical cell in this pack is rated at 63.36Wh, matching OEM spec. Run a full discharge-to-hibernate and uninterrupted recharge cycle; the BIOS will update its reported figure as it builds a new charge model.
My Averatec 2100 fuel gauge is jumping around wildly — showing 80%, then 45%, then 70% within minutes of unplugging.
The fuel gauge IC uses a charge model calibrated against the previous cell's internal resistance and discharge curve. A brand-new cell has different characteristics, so the model is off and the gauge swings erratically until it learns the new cell's behaviour. This is not a fault with the replacement pack. Run three complete cycles — discharge to automatic hibernate cutoff each time, then charge fully to 100% without interrupting — and the gauge will stabilise.
The new battery in my Averatec 2100 stopped charging at 80% and won't go higher — is the charger the problem?
Some Averatec BIOS versions include a charge-limit setting that caps charging at 80% to reduce long-term cell stress — this is a firmware-controlled threshold, not a charger or battery fault. Check the BIOS power management page (typically under Power or Battery on the Advanced tab) for a charge limit or battery care mode setting and disable it. If no such setting exists, the BMS may be waiting for a recalibration trigger; discharge the laptop fully to hibernate, then charge uninterrupted straight through to 100% to allow the BMS to re-establish its full charge endpoint.
