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 ProBook 5330m — 14.8V Li-Polymer Replacement Battery (635146-001)
This is a 14.8V, 2700mAh (39.96Wh) Li-Polymer replacement battery for the HP ProBook 5330m 13.3-inch business notebook. It fits the ProBook 5330m series across multiple regional variants, including the LV720PA, QC518PA, and SP451UC. OEM cross-references include FN04, HSTNN-DB0H, QK648AA, and 634818-271.
- ProBook 5330m series compatibility: All ProBook 5330m variants share the same 14.8V four-cell Li-Polymer voltage rail, connector pinout, and BMS handshake protocol — that is why one part number covers the full regional lineup.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a ProBook 5330m unit. The BMS completed the full handshake, reported cell presence correctly in BIOS, and charge termination triggered cleanly at 16.8V across all four cells.
- Post-install calibration on the ProBook 5330m: After fitting this battery, run one full discharge to hibernate-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 on this platform.
BIOS reporting battery health as poor after replacement
The ProBook 5330m BIOS reads health data stored in the battery's EEPROM. When a new cell is installed, the EEPROM contains factory defaults that don't match the BIOS's accumulated charge history from the old battery. The system flags this mismatch as a health warning — it is not a fault with the replacement cell. Running one full discharge-to-hibernate followed by a full uninterrupted charge completes the battery learn cycle and clears the warning.
ProBook 5330m shutting down at 20–30% charge shown
This happens when the fuel gauge IC has not yet calibrated against the new cell's actual discharge curve. The gauge estimates remaining charge using data from the old, degraded cell — so it reads 25% while the new cell is already near its voltage floor. Under full CPU and display load, the cell hits its low-voltage cutoff faster than the gauge predicts, and the laptop shuts off without warning. Run two to three full discharge-to-hibernate and full recharge cycles until the gauge stabilises — the cutoff should shift below 10% once calibration is complete.

Frequently Asked Questions
The ProBook 5330m BIOS shows the wrong Wh rating after I installed the new battery — is something wrong with the cell?
No — this is an EEPROM mismatch, not a cell fault. The replacement battery's EEPROM reports the rated chemistry capacity, while the BIOS compares it against the charge history written by the original cell. The figure normalises after one or two full calibration cycles. Check the Wh reading again after completing a full discharge-to-hibernate and an uninterrupted charge to 100%.
My ProBook 5330m fuel gauge swings wildly — it jumped from 60% to 15% in minutes after fitting the new battery.
The fuel gauge IC on the ProBook 5330m calibrates its discharge curve against the cell it learns over time. A new cell has a different internal resistance and capacity profile than the worn cell the gauge was trained on, so early readings are unreliable. The gauge needs two to three full discharge-and-recharge cycles to map the new cell's actual voltage curve. Run those cycles with the laptop under normal load — do not interrupt the charge — and the readings will stabilise.
The new battery stopped charging at 80% on the ProBook 5330m and will not go higher — is the cell faulty?
This is almost always a BIOS-controlled charge limit, not a battery fault. HP's battery management firmware on some ProBook 5330m units activates a charge threshold — typically 80% — to reduce cell stress during long AC-connected sessions. Check HP Support Assistant or the BIOS Power settings for a "Battery Health Manager" or charge limit option and set it to "Maximise my battery." Once disabled, the cell will charge to the full 16.8V termination point.
