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.

HP Omen 17-W100NC — 11.55V Li-ion Replacement Battery (852801-2C1)
This 11.55V, 8200mAh (94.71Wh) Li-ion battery replaces the original pack in the HP Omen 17-W100 series gaming laptops. It fits the Omen 17-W100NC alongside over 260 compatible variants, including the W100NF, W100NG, and W100NK. OEM part numbers covered include 852801-2C1, 853294-850, 853294-855, HSTNN-DB7M, and PF06XL.
- Omen 17-W100 series compatibility: These models share the same six-cell Li-ion architecture, connector pinout, and BMS handshake protocol. The SMBus communication lines are identical across the W100 variants, so one cell fits the entire range without firmware conflicts.
- Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the Omen 17 platform. The BMS negotiated correctly with the BIOS, charge acceptance started immediately at plug-in, and the protection circuit responded to over-discharge cutoff within spec.
- Post-install calibration step: After fitting this cell, run the laptop on battery until it hibernates at low charge, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap.
BIOS reporting poor battery health immediately after fitting a new cell
The HP Omen 17 BIOS reads health data from EEPROM embedded in the battery pack. When a new cell goes in, the EEPROM carries fresh data that the BIOS has never seen, so it flags the pack as unknown or degraded. This is not a fault with the replacement cell — it is the BIOS comparing stored charge history against a blank slate. Run one full discharge-to-hibernate followed by an uninterrupted charge to 100%, and the learn cycle rewrites the health register. After two to three cycles, the BIOS health readout will stabilise.
Laptop shutting down at 20–30% charge shown on screen
This happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The IC still references the old cell's discharge profile, so it calls shutdown early — the displayed percentage does not match real cell voltage. Under combined CPU and display load, voltage drops faster than the uncalibrated gauge predicts, triggering a protective shutdown. Run two full discharge cycles — letting the laptop hibernate rather than cutting power manually — then charge to 100% each time. By the second cycle, the fuel gauge IC re-maps the curve and the shutdown-at-30% behaviour stops.

Frequently Asked Questions
HP Support Assistant says my new battery health is "Poor" straight out of the box — is the cell faulty?
The cell is not faulty. The HP BIOS reads health data from the battery's EEPROM, and a fresh cell carries no charge history, so the system flags it as degraded by default. Run one full discharge to hibernate-cutoff, then charge uninterrupted to 100% — this triggers the BIOS battery learn cycle and overwrites the health register with real data. After two cycles, the health status will update to a normal reading.
My Omen 17 shuts off at around 25% shown, but the battery is brand new — what's causing it?
The fuel gauge IC inside the laptop calibrates its discharge curve against the old cell's voltage profile. With a new cell installed, the curve is mismatched, so the gauge calls a low-voltage shutdown before the cell is actually empty. Under heavy CPU and GPU load, the voltage drop is steeper, which makes the mismatch worse. Let the laptop discharge fully to hibernate twice in a row, charging to 100% between each cycle — by the second pass the IC re-maps to the new cell's curve and the early shutdowns stop.
Windows is showing my new battery's Wh rating as lower than the spec — is something wrong?
The Wh figure Windows reads comes from the EEPROM on the battery pack, not from live cell measurement. On a fresh replacement, the EEPROM may report a rated value that differs slightly from the chemistry's actual capacity until the fuel gauge IC completes its calibration cycles. The cell itself delivers its full 94.71Wh — Windows is reading stored metadata, not measured output. After two full charge-discharge cycles, the reported Wh figure will align with the cell's real capacity.
