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 Pavilion Touchsmart 14 / 15 — 14.8V Li-ion Replacement Battery (728460-001)
This 14.8V, 2200mAh (32.56Wh) Li-ion cell replaces the original HP battery across the Pavilion Touchsmart 14 and Touchsmart 15 notebook lines. It fits a wide range of sub-models including the 14-N048CA and 14 B109WM. OEM part numbers covered include LA04, OA03, OA04, HSTNN-UB5M, HSTNN-UB5N, TPN-Q129 through TPN-Q132, and several hundred additional HP cross-references.
- Touchsmart 14 and 15 series compatibility: Both lines share the same 14.8V four-cell architecture, LA04/OA04 connector standard, and BMS handshake protocol — one cell fits both platforms without modification.
- Bench tested on actual hardware: We ran this cell on a Pavilion Touchsmart 14 chassis. The BMS negotiated correctly, charge acceptance reached full capacity, and the protection circuit responded to overcurrent and over-temperature thresholds as expected.
- First-cycle calibration on Touchsmart models: After installing, 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 on-screen after every cell swap.
BIOS reporting poor battery health after swapping the Touchsmart cell
The Pavilion BIOS reads health data from the battery's EEPROM on first contact. When a new cell arrives, the EEPROM counters are at zero and don't match the aged-profile the BIOS expects — so it flags the battery as unknown or degraded. This is a data mismatch, not a fault with the cell. Running one complete discharge-to-hibernate followed by an uninterrupted full charge gives the BIOS fuel gauge IC enough data to recalibrate. After two or three cycles the health indicator typically returns to normal.
Touchsmart shuts down unexpectedly at 20–30% charge shown
This happens when the cell voltage drops below the BMS cutoff threshold under combined CPU and display load — the fuel gauge still reads 20–30% but the actual cell voltage has already hit the floor. It's a voltage-cliff problem common to Li-ion cells that have partially degraded, or to a new cell whose gauge IC hasn't calibrated yet. On a freshly installed cell, run the full discharge-and-recharge calibration cycle described above. If the shutdowns persist after three cycles, check that the BIOS is not limiting discharge — enter BIOS setup and confirm no battery protection floor is set above 3.0V per cell.

Frequently Asked Questions
The HP laptop shows the new battery as "0%" and won't start charging — what's happening?
The BIOS fuel gauge IC has no calibration data for the new cell and is reading the EEPROM as blank, so it reports 0% and holds the charge circuit open. Plug in the AC adapter and leave the laptop connected for at least 30 minutes without pressing the power button — the charge controller usually starts a trickle-charge initialisation pass before the gauge updates. If it still shows 0%, perform a hard reset: shut down, disconnect AC, hold the power button for 15 seconds, reconnect AC, then power on. The gauge should begin counting up from a valid voltage reading above 10.8V.
Windows is reporting the battery capacity as a completely wrong Wh figure — much lower than 32.56Wh — is the cell faulty?
The Wh figure Windows displays is pulled from the battery EEPROM's rated-capacity field, which reflects the cell's factory-programmed nominal value. If that figure doesn't match the 32.56Wh in the product specs, the EEPROM is storing a different rated baseline — this is a data reporting difference, not a sign the cell is underperforming. The actual energy the cell delivers is determined by chemistry and load, not by what the EEPROM reports. Run two full discharge-to-hibernate and full-recharge cycles; after calibration, the OS reading typically aligns closer to the rated value.
The replacement battery charges to around 80% and then stops — is the charge limit a defect?
This is a BIOS-controlled charge threshold, not a fault with the cell. HP includes a Battery Care function in BIOS (and HP Support Assistant) that caps charging at 80% to reduce cell stress during AC-connected use. Open BIOS setup at startup (typically F10), navigate to the Power or Battery menu, and set the charge limit to 100%. The same setting is accessible in HP Support Assistant under Battery Health Manager — switch it from "Maximize my battery health" to "Let HP manage my battery charging."
