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 Envy 17-CH Series — 15.12V Li-Polymer Replacement Battery (HSTNN-IB9T)
This is a Li-Polymer replacement battery for the HP Envy 17-CH laptop series, including the Envy 17-CH0005UA and over 200 compatible models. It runs at 15.12V with a 3650mAh (55.19Wh) capacity. OEM part numbers covered include HSTNN-IB9T, TI04XL, M24420-1D1, and M24563-005.
- Envy 17-CH series compatibility: Every model in the 17-CH lineup shares the same 15.12V four-cell architecture, internal connector pinout, and BMS communication protocol. That common hardware base is why one cell fits the entire range, from the CH0005UA to the CH0010CA and CH0011NB.
- Bench tested on actual hardware: We cycled this cell through full charge and discharge on a CH-series board. The BMS handshake completed without error codes, charge current tapered correctly at the top-of-charge threshold, and the protection circuit tripped cleanly at the low-voltage cutoff.
- First-cycle calibration on the 17-CH: After fitting this cell, run the laptop unplugged until it hibernates on its own, then charge uninterrupted to 100% without using the machine. This lets the BIOS battery-learn cycle reset against the new cell's actual capacity and clears the inaccurate health warning that appears on every cell swap in this series.
BIOS reporting poor battery health immediately after fitting a new cell
The HP Envy 17-CH stores battery state data in the BIOS. When a new cell goes in, that stored data reflects the worn-out history of the old pack — not the new one. The BIOS has not yet run a learn cycle against the fresh cell, so it flags health as poor or unknown. One full discharge-to-hibernate followed by an uninterrupted charge to 100% rewrites that data. After two to three cycles, the health indicator will update to reflect the actual condition of the new cell.
Laptop shuts down at 20–30% battery remaining shown on screen
This is a voltage-cliff problem, not a fuel gauge error. Under full CPU and display load, the cell's terminal voltage drops faster than the fuel gauge IC can update — the system hits the hardware undervoltage cutoff while the OS still shows charge remaining. It happens most often in the first few cycles before the fuel gauge IC has calibrated against the new cell's discharge curve. Run two or three full discharge-to-hibernate cycles without interrupting. After that, the IC's internal model aligns with the actual cell, and the shutdowns stop.

Frequently Asked Questions
HP Envy 17-CH shows "0% available (plugged in, charging)" after I swapped the battery — is the new cell dead?
It is not dead. The fuel gauge IC on the 17-CH board still holds EEPROM data from the old, depleted cell — so it initialises the new cell at zero and gets confused by the mismatch. Plug in the charger, let it charge uninterrupted to 100%, then unplug and run the laptop down to hibernate. That first full cycle resets the IC's state-of-charge model against the actual new cell. The percentage display corrects itself within one to two cycles after that.
Windows is showing this replacement battery as 55Wh but HP Support Assistant reports a different Wh figure — which one is correct?
The 55.19Wh figure in Windows Device Manager pulls directly from the cell's EEPROM — that is the correct rated value for this pack (15.12V × 3650mAh). HP Support Assistant sometimes reads a cached or firmware-stored value from the old cell's profile before the BIOS learn cycle completes. Run one full discharge-to-hibernate and recharge cycle, then check Support Assistant again — it will re-read the EEPROM and the figures will align.
New battery on my HP Envy 17-CH stops charging at 80% and never goes higher — how do I fix this?
This is almost always the HP Battery Care Manager or a BIOS-level charge limit, not a fault with the cell. HP's firmware includes an 80% charge cap that activates automatically when battery care mode is turned on. Open HP Command Center or OMEN Gaming Hub if installed, locate Battery Health Manager, and switch it from "Maximize my battery health" to "Let HP manage my battery." If that setting is not visible, enter the BIOS setup at startup, find the Battery Care Mode option under System Configuration, and disable it.
