It slots into the same bay, uses the same connector, and communicates with the same BMS interface as the factory cell. Capacity figures are taken directly from product data — not extrapolated from web sources.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e15-h000 and 15-S000 platform fit:\u003c\/strong\u003e\n    These two series share the same battery bay dimensions, connector pinout, and BMS handshake protocol — which is why a single cell covers both. The 274.00 × 39.35 × 20.60mm form factor matches the original enclosure exactly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge-discharge cycle on a 15-S100 unit. The BMS accepted the new cell without fault codes, charge termination triggered correctly at 100%, and voltage held steady across the cycle with no unexpected cutoffs.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle on the Presario platform:\u003c\/strong\u003e\n    After fitting this battery, run the laptop on battery power until it hibernates at the low-voltage cutoff, then charge it 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.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Presario 15 BIOS flags a new battery as poor health\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Presario 15 platform stores learned battery data in EEPROM — charge capacity, internal resistance, and cycle count — from the old cell. When a new cell goes in, the BIOS compares its readings against that stored baseline and immediately marks health as degraded. This is not a fault with the replacement cell. One complete discharge-to-hibernate followed by a full uninterrupted charge gives the BIOS enough data to overwrite the old EEPROM values. After that single calibration cycle, the health indicator returns to normal on most units.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFuel gauge showing wildly different percentages across the first few cycles\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on these notebooks estimates state-of-charge by comparing real-time voltage against a learned discharge curve from the previous cell. A brand-new cell has a slightly different voltage-to-capacity curve, so the IC reports inaccurate percentages — often jumping 10–20% in either direction. This self-corrects after two to three full discharge and charge cycles as the IC recalibrates against actual cell behaviour. If the gauge is still erratic after four cycles, check that the battery is reaching a terminal charge voltage of 16.8V before the charger cuts off.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409804034138,"sku":"BWCS-HPV140NB-1","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409804066906,"sku":"BWCS-HPV140NB-2","price":109.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409804099674,"sku":"BWCS-HPV140NB-3","price":118.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPV140NB-1.webp?v=1779580992","url":"https:\/\/batteryweb.com\/products\/compaq-presario-15-h000-replacement-battery-144v-2450mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
