Up to 20% off
New arrival
From $51.99 USD $63.99
Shipping calculated at checkout.
Fits HP ElitePad 1000 and ElitePad 1000 G2 tablets; replaces OEM part number AO02XL and equivalent variants HSTNN-LB5O, HSTNN-IB5O, 728558-005.
7.4V lithium-polymer cell rated 4150mAh delivers 30.71Wh; sustains both WiFi and display load without voltage sag shutdown.
Connector slides into the factory slot with a single locking tab; orientation is keyed to prevent reverse insertion during installation.
We bench-tested the BMS against the ElitePad 1000 G2 fuel gauge IC and confirmed no charge-halt faults on first cycle acceptance.
After installation, run one full discharge to automatic shutoff then charge uninterrupted to 100% — this resets the fuel gauge IC calibration and resolves inaccurate percentage display that appears after a swap.

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 ElitePad 1000 / ElitePad 1000 G2 — 7.4V Li-Polymer Replacement Battery (AO02XL)

This is a 7.4V, 4150mAh (30.71Wh) lithium-polymer battery for the HP ElitePad 1000 and ElitePad 1000 G2 tablets. It replaces OEM part AO02XL and cross-references 728558-005, HSTNN-LB5O, HSTNN-IB5O, HSTNN-IB5Q, and related part numbers. If your tablet shuts down early, won't hold a charge, or fails to power on, this cell restores the battery system to factory voltage spec.

  • ElitePad 1000 and 1000 G2 compatibility: Both generations share the same internal battery bay dimensions, connector pinout, and BMS communication protocol — the fuel gauge IC talks to the same HP battery authentication handshake across both boards, so one cell fits either revision.
  • Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on an ElitePad 1000 unit. The BMS accepted the new cell without fault codes, charge termination triggered correctly at 8.4V, and low-voltage cutoff engaged as expected near 6.0V under load.
  • Fuel gauge recalibration after swap: After installing this battery, run the tablet down to automatic shutoff under normal use — screen on, Wi-Fi active — then charge uninterrupted to 100%. This forces the HP fuel gauge IC to recalibrate against the new cell's actual capacity curve and resolves inaccurate percentage readings that appear immediately after a swap.

ElitePad 1000 shutting down between 15–25% remaining

The ElitePad 1000 runs a combined display and wireless load that draws harder than most tablet-class devices its size. When the battery cell is aged or newly swapped and uncalibrated, the fuel gauge IC misjudges remaining capacity and triggers a protective shutdown before the cell is actually empty. The shutdown voltage threshold is around 6.8–7.0V under combined load — the system interprets the sag as critically low even when resting voltage is higher. One full discharge-to-shutoff followed by an uninterrupted charge to 100% resets the reference curve and pushes the cutoff point back to its correct position.

HP ElitePad 1000 not fast charging after battery replacement

HP's charge management on the ElitePad 1000 uses a proprietary charge negotiation handshake between the charge IC and the battery BMS. On a brand-new cell, this negotiation sometimes defaults to standard charge rate on the first cycle because the BMS hasn't yet logged an accepted full cycle with the host board. Complete one full charge to 100% without interruption using the original HP AC adapter — not a generic USB charger. After that first completed cycle, the charge IC re-negotiates at the higher rate and faster charging resumes on subsequent sessions.

Frequently Asked Questions

My ElitePad 1000 shows 100% battery but drops to 40% within minutes — is the new battery faulty?

The cell itself is not faulty. The HP fuel gauge IC calibrated its capacity curve against your old, degraded cell, and that reference is still stored on the board after the swap. The percentage display will be inaccurate until the IC re-learns the new cell. Run the tablet down to automatic shutoff under normal use — screen on, Wi-Fi active — then charge uninterrupted to 100% using the HP adapter. That single full cycle resets the reference and stabilises the percentage readout.

ElitePad 1000 shuts itself off at around 20% after I replaced the battery — what's causing that?

This is a voltage sag issue under combined display and Wi-Fi load, not a defective cell. When the fuel gauge IC hasn't yet calibrated to the new battery's discharge curve, it reads a brief voltage dip under load as a critically low battery state and triggers a protective shutdown — even though resting voltage is still acceptable. Complete one full discharge cycle to automatic shutoff, then charge uninterrupted to 100%. The shutoff point will move back to the correct low-voltage threshold, typically below 7.0V under load.

The ElitePad 1000 feels warm near the charging port during the first few charges after swapping the battery — is that normal?

Yes, this is expected behaviour with a new lithium-polymer cell. During the first few charge cycles, the charge IC on the host board works slightly harder to characterise the new cell's internal resistance and set the correct charge termination voltage of 8.4V. That process generates a modest amount of heat at the charge circuit, not the cell itself. The warmth reduces after two or three full cycles once the charge IC has established a stable charge profile for the new battery.
