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.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eElitePad 1000 and 1000 G2 compatibility:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eElitePad 1000 shutting down between 15–25% remaining\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 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.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHP ElitePad 1000 not fast charging after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eHP'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.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426037465178,"sku":"BWCS-HPE100SL-1","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426037497946,"sku":"BWCS-HPE100SL-2","price":60.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426037530714,"sku":"BWCS-HPE100SL-3","price":67.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPE100SL-1.webp?v=1779930219","url":"https:\/\/batteryweb.com\/products\/hp-elitepad-1000-replacement-battery-74v-4150mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
