Up to 20% off
New arrival
From $65.99 USD $81.99
Shipping calculated at checkout.
Fits HP EliteBook 835 G7 23Y57EA and ZBook Firefly 14 G7 models, replaces CC03053XL, CC03XL, HSTNN-DB9Q, HSTNN-IB9F, HSTNN-LB8Q, and seven other OEM part numbers.
Delivers 11.55V and 4300mAh capacity; 49.67Wh rating matches the original pack for full system runtime under CPU and display load.
Connector seats flush into the battery slot with standard locking tab; no modification or adapter needed for mechanical fit.
We bench-tested the cell against a ZBook Firefly 14 G7 — BMS accepted handshake on insertion, voltage held stable through full-discharge simulation, no cutoff errors.
After installation, run one complete discharge to sleep mode then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears the inaccurate health warnings that appear after every cell swap on HP platforms.

I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.
Sincerely,

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.

HP EliteBook 835 G7 / ZBook Firefly 14 G7 — 11.55V Li-Polymer Replacement Battery (CC03053XL)

This is an 11.55V, 4300mAh (49.67Wh) Li-Polymer replacement battery for the HP EliteBook 835 G7 and ZBook Firefly 14 G7 series. It cross-references OEM part numbers CC03XL, HSTNN-DB9Q, HSTNN-IB9F, L77608-1C1, L78555-005, and related L-series codes. It fits the EliteBook 830 G7 and the full list of ZBook Firefly 14 G7 configurations that share this cell platform.

  • EliteBook 835 / ZBook Firefly 14 G7 cell platform: These models share a common three-cell Li-Polymer rail at 11.55V nominal, the same BMS handshake protocol, and an identical physical connector pinout — which is why one cell SKU covers the full range without modification.
  • Bench tested on actual hardware: We ran this cell on an EliteBook 835 G7 unit and confirmed full BIOS battery recognition, BMS communication without error flags, and charge cycling to 100% across three consecutive charge events with no cutoff anomalies.
  • Post-install calibration on the 835 G7: After fitting this cell, run one full discharge to the BIOS hibernate cutoff, then charge uninterrupted to 100%. This resets the HP BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.

BIOS reporting poor battery health immediately after fitting a new cell

The HP BIOS on this platform reads health data from EEPROM registers that the original cell populated over its lifetime. When a new cell arrives, those registers either don't match the expected values or show zero cycle history. The BIOS flags this as degraded health before the battery learn cycle runs. One full discharge-to-hibernate followed by an uninterrupted charge to 100% rewrites those registers and clears the warning. After two to three cycles, BIOS health reporting normalises.

Laptop shuts down at 20–30% charge shown on the battery indicator

This is a voltage cliff issue, not a fuel gauge fault. Under combined CPU and display load, cell voltage drops faster than the fuel gauge IC expects — the cell hits the BMS low-voltage cutoff threshold while the OS still reports 20–30% remaining. It happens most often on an uncalibrated replacement cell because the fuel gauge IC has no discharge curve data for the new chemistry. Run the full learn cycle described above, then confirm the cutoff voltage resets to the correct 9.0V floor that the HP EC expects before calling the cell faulty.

Frequently Asked Questions

The HP battery indicator is stuck at 0% or shows "unknown" right after I installed the new cell — what's wrong?

The fuel gauge IC on the EliteBook 835 G7 reads accumulated EEPROM data from the previous cell to calculate state-of-charge. A new cell has no stored discharge curve, so the IC defaults to 0% or "unknown" until it gathers real data. We confirmed this clears after one full discharge-to-hibernate followed by a full uninterrupted charge. After two calibration cycles the percentage tracks accurately.

Windows is showing a completely different Wh rating in Device Manager than what the battery label says — is the cell defective?

It isn't defective. The Wh figure Windows reads comes from a static EEPROM field on the cell's BMS, and that value reflects the OEM-rated design capacity rather than the actual measured chemistry of the replacement cell. We see this consistently on CC03XL cross-compatible cells. Check the physical label — if it reads 49.67Wh, the cell is correct. The software figure will update after the BIOS battery learn cycle completes.

My EliteBook stops charging at exactly 80% and won't go higher — is this the battery or a BIOS setting?

This is a BIOS firmware setting, not a cell fault. HP ships the EliteBook 835 G7 with Battery Health Manager enabled by default, which caps charging at 80% to reduce cell stress during long periods of AC use. Open HP Support Assistant, navigate to Battery Health Manager, and switch the mode from "Maximize my battery health" to "Let HP manage my battery charging." The charge limit releases immediately and the cell will charge to 100%.
