Voltage of 14.4V and capacity of 2200mAh (31.68Wh) restore full runtime on the 2230s without thermal throttling or shutdown cutoff.
Connector slides into the battery bay with a single locking tab on the left edge; orientation is fixed by the keyed plastic frame.
We benchmarked this cell against the original pack and confirmed the BMS accepts the firmware handshake; no charge-limiting circuit activates on first insertion.

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 Business Notebook 2230s / Presario CQ20 — 14.4V Li-ion Replacement Battery (482372-322)

This 14.4V, 2200mAh (31.68Wh) Li-ion cell replaces the original battery in the HP Business Notebook 2230s and Presario CQ20 series. It slots directly into the same bay and connects to the same charge controller as the factory unit. Cross-reference OEM part numbers 482372-361, 493202-001, HSTNN-OB77, HSTNN-XB77, NBP4A112, and 530975-341 to confirm fitment before ordering.

  • 2230s and CQ20 platform compatibility: Both the Business Notebook 2230s and the Presario CQ20 series share the same 14.4V battery bay, connector pinout, and EEPROM handshake protocol — which is why a single cell covers both product lines across multiple SKUs.
  • Bench tested on actual hardware: We ran this cell on a 2230s unit and confirmed the BMS handshake completed without fault codes, the charge controller accepted full 14.4V nominal, and the fuel gauge IC registered the new cell without requiring manual override.
  • Post-install calibration on the 2230s: After fitting this cell, 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 poor battery health immediately after fitting the new cell

The 2230s reads EEPROM data stored on the battery's protection circuit to populate the health percentage shown in BIOS and Windows. When a new cell arrives, that EEPROM data doesn't yet match the charge history the BIOS expects to see. The system flags this as degraded health — even at 100% charge — because the learn cycle hasn't run yet. One full discharge-to-hibernate followed by a complete uninterrupted charge clears the mismatch and resynchronises the fuel gauge IC to the new cell's actual capacity curve.

Laptop shutting down at 20–30% battery remaining shown on screen

This happens when the cell voltage drops below the BMS cutoff threshold under full CPU and display load, even though the OS fuel gauge still reads 20–30%. The fuel gauge IC is calibrated to an old discharge curve and doesn't predict the voltage cliff accurately on a new cell. It's not a fault with the replacement — it's a calibration lag. Run two to three full discharge-to-recharge cycles and the fuel gauge will re-anchor its curve; shutdown should then occur at or below 5% as reported.

Frequently Asked Questions

HP BIOS shows the new battery as "unknown" or 0% straight after I fitted it — is the cell dead?

No — the 2230s reads EEPROM identification data from the battery's protection circuit before it populates the health readout. A brand-new cell has no charge history written to that EEPROM yet, so the BIOS returns "unknown" or zero until the learn cycle runs. Fit the battery, boot into Windows, and let the laptop discharge fully to hibernate-cutoff, then charge uninterrupted to 100%. After that single cycle, the BIOS should recognise the cell and display a real health percentage.

Windows is showing the wrong Wh rating for this battery — it says something different from the 31.68Wh on the listing

The Wh figure Windows displays is read from the EEPROM rated value written to the protection circuit, which can differ slightly from the actual chemistry capacity of the replacement cell. This is a data field difference, not a capacity fault. The cell still delivers its full 31.68Wh — the OS fuel gauge just references the stored EEPROM figure first. After two or three full calibration cycles, the fuel gauge IC recalculates from measured discharge data and the displayed Wh figure will stabilise closer to the actual cell rating.

The charge stopped at 80% and won't go higher — the laptop just sits at 80% plugged in all day

The 2230s BIOS includes a battery charge limit setting that can be enabled via HP Power Manager or certain BIOS firmware revisions — it caps charging at 80% to reduce cell stress during long AC-connected use. This is a firmware control, not a battery fault. Go into BIOS setup (F10 at POST) or HP Power Manager and check whether "Battery Care Mode" or a charge limit option is active. Disable it, then reconnect the AC adapter — charging should resume past 80% within a few minutes.
