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.

Compaq Pavilion ZE5512AP / OmniBook XE4500s — 14.8V Li-ion Replacement Battery (319411-001)
This is a 14.8V 4400mAh (65.12Wh) Li-ion replacement battery for a wide range of Compaq Pavilion and OmniBook notebooks. Confirmed fit includes the Pavilion ZE5512AP-DR222A, OmniBook XE4500s-F4867HG, Pavilion ZE4910US-M033UA, and Pavilion XT118-F5861H among over a thousand verified models. OEM cross-references are 319411-001, 361742-001, and F4809A.
- Pavilion ZE / OmniBook XE4500s platform fit: These models share a common 14.8V four-cell Li-ion architecture with the same connector pinout and BMS communication protocol. The fuel gauge IC and charge controller in the laptop handshake to this voltage rail directly — swapping a lower-voltage pack from another Compaq line will not work here.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on a ZE-series chassis. The BMS accepted the pack without error codes, charge termination triggered correctly at full voltage, and the protection circuit tripped cleanly at the low-voltage cutoff floor — no runaway, no false disconnect mid-draw.
- First-cycle reset on ZE-series BIOS: After installing, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity and clears the inaccurate health warning that appears after every cell swap on this platform.
Why the Pavilion ZE shuts down at 20–30% after a battery swap
The ZE-series BIOS tracks discharge curves from the previous cell and maps percentage readings against that old profile. When a new cell is installed, the fuel gauge IC is still referencing stale data, so the laptop's reported percentage drifts from actual cell voltage. Under full CPU plus display load, voltage drops faster than the outdated profile expects — the BMS sees it hit the hardware cutoff floor and triggers an immediate shutdown even though the gauge still shows charge remaining. Running two full calibration cycles corrects the mapping and eliminates the early cutoff.
BIOS showing "poor health" or "unknown battery" straight out of the box
This happens because the EEPROM data embedded in the replacement cell carries rated chemistry values that differ slightly from the original OEM cell's stored parameters — the BIOS reads those values on first boot and flags the mismatch as a fault. It is not a defective battery. Boot into the Compaq BIOS utility, clear any stored battery data if the option exists, then run a full discharge-to-hibernate followed by a complete uninterrupted charge. After one full learn cycle the health status resolves to normal.

Frequently Asked Questions
My Pavilion ZE's fuel gauge jumps from 60% to 15% with no warning — is the new battery faulty?
The fuel gauge IC needs calibration cycles against the new cell before its readings stabilise. The old cell's discharge curve is still stored in the BIOS, so voltage readings and percentage displays are out of sync. Run two full discharge-to-hibernate then charge-to-100% cycles without interrupting either phase. After the second cycle the gauge IC recalibrates and the erratic jumping stops.
The replacement battery shows a different Wh rating in system info than the original — should I be concerned?
The Wh figure shown in Windows or the BIOS is read from the EEPROM on the battery's BMS board, not measured live. Replacement cells use rated chemistry values that can differ by a few Wh from the original OEM EEPROM entry. The actual stored energy at 14.8V and 4400mAh is 65.12Wh — if the figure shown is close to that, the cell is correct. No action is needed; this is a data label difference, not a capacity difference.
New battery installed but the laptop won't charge past 80% — is there a fix?
On ZE-series Compaq notebooks, a BIOS-controlled charge limit can activate after a battery replacement, capping charge at 80% as a conservative protection measure. This is firmware behaviour, not a battery fault. Enter the BIOS setup on next boot, check the Power Management section for any battery charge threshold or conservation mode setting, and disable it. If no such setting exists, perform a full discharge to hibernate-cutoff and charge to 100% uninterrupted — this clears the limit on most ZE-series units.
