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 Stream 11-R Series — 7.6V Li-Polymer Replacement Battery (PO02XL)
This 7.6V, 4800mAh (36.48Wh) lithium-polymer cell replaces the original PO02XL battery in the HP Stream 11-R015WN and the broader Stream 11-R series. It fits the slim 3.90mm profile of the Stream 11 chassis and connects to the same BMS handshake the firmware expects. Voltage and capacity match the OEM spec exactly.
- Stream 11-R series compatibility: The Stream 11-R014WM, R015WN, R010NR, and 237+ other Stream 11-R variants share the same 7.6V two-cell Li-Polymer pack, identical connector pinout, and the same BMS communication protocol — so one SKU covers the full lineup without modification.
- Bench tested on actual hardware: We ran this cell on a Stream 11-R unit and confirmed the BMS handshake completed on first boot, charge current ramped correctly through CC/CV phases, and the protection circuit triggered at the expected low-voltage cutoff without requiring a manual reset.
- Stream 11 post-swap calibration: After installing, run a full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell's EEPROM data and clears the inaccurate health warning that appears after every cell swap on Stream 11 hardware.
BIOS reporting poor battery health immediately after fitting a new cell
The HP Stream 11 BIOS reads health data from the battery's EEPROM, not from live cell measurements. When a new cell arrives, the EEPROM holds factory default values that don't match the BIOS's learned profile from the old pack. The firmware flags this mismatch as "poor health" or "consider replacing." Running one full discharge-to-hibernate followed by a complete uninterrupted charge resets the learn cycle. After two to three cycles the BIOS recalibrates and the warning clears.
Stream 11 shutting down at 20–30% charge shown on screen
This happens when the fuel gauge IC hasn't calibrated against the new cell's actual voltage curve. The displayed percentage is still mapped to the old cell's degraded curve, so the laptop reaches a real voltage cliff — typically around 6.8V under CPU and display load — while the gauge still reads 25%. The fix is the same calibration cycle: drain to hibernate-cutoff, then charge to 100% without interruption. After two full cycles the gauge IC locks onto the new curve and the premature shutdown stops.

Frequently Asked Questions
HP Stream 11 BIOS shows 0% or "unknown" on the new battery — is the cell dead?
No — the Stream 11 BIOS loses its battery profile when the old cell is removed and can't read the new cell's EEPROM until it completes a learn cycle. Boot the laptop on AC power, let it charge to 100%, then disconnect AC and run it down to hibernate-cutoff. Reconnect AC and charge uninterrupted to 100%. After that full cycle the BIOS recognises the cell and the 0% or "unknown" reading clears.
The Stream 11 charge stops at 80% and won't go higher — is the replacement battery faulty?
This is a BIOS-controlled charge limit, not a fault with the cell. HP's firmware on some Stream 11 units activates an 80% charge cap when it detects what it reads as a degraded or unrecognised battery — triggered by EEPROM mismatch after a swap. Run the full calibration cycle first: discharge to hibernate, then charge uninterrupted to 100% on a cool, idle machine. If the cap persists, check HP Support Assistant for a BIOS update, as several Stream 11 firmware revisions patched this threshold behaviour.
System info shows the wrong Wh rating after fitting the PO02XL replacement — should it read 36.48Wh?
The Wh figure in Windows Device Manager or HWiNFO pulls from the battery EEPROM's rated design capacity, which can differ from the actual chemistry value until the fuel gauge IC recalculates it against real charge cycles. This cell is rated at 36.48Wh. If Windows reports a different number immediately after install, run two full discharge-and-charge cycles — the fuel gauge IC updates its stored Wh calculation each cycle and the displayed value will converge to the correct figure by cycle three.
