It fits the B1200, B1202VU, B1223TU, B1255TU, and over 100 additional Presario B1200 variants. OEM part numbers covered include 454001-001, 447649-251, HSTNN-DB53, HSTNN-OB53, and 447649-321.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePresario B1200 platform fit:\u003c\/strong\u003e\n    Every model in this series runs the same 14.4V power rail with an identical connector and BMS handshake protocol. That shared architecture means one cell works across the full B1200 lineup without modification or adapter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a Presario B1200 chassis and monitored BMS communication throughout charge and discharge. The protection circuit responded correctly to both overcharge cutoff and low-voltage shutoff without tripping spurious fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e\n    After fitting this battery, run the laptop on battery power until it reaches hibernate-cutoff, then charge uninterrupted to 100% without interruption. 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\"\u003eBIOS reporting poor battery health immediately after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Presario B1200 BIOS reads health data stored in the battery's EEPROM and compares it against the old cell's charge history. A fresh cell carries no discharge history, so the BIOS flags it as degraded or unknown on first boot. This is not a fault with the replacement cell — it is a mismatch between the EEPROM baseline and the new cell's state. Run one full discharge-to-hibernate then a complete uninterrupted charge; the BIOS rewrites the learned capacity baseline and the health warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts off at 20–30% charge shown on the status bar\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The gauge is still using the old cell's parameters, so it miscalculates remaining capacity and triggers a low-battery shutdown while meaningful charge is still available. The cell itself is not defective — the IC simply needs two or three full discharge-to-charge cycles to re-map the curve. After those cycles, the reported percentage at shutdown should drop to 3–5%, which is the normal BMS low-voltage cutoff threshold for this chemistry.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410865061978,"sku":"BWCS-HTB1200HB-1","price":77.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410865094746,"sku":"BWCS-HTB1200HB-2","price":89.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410865127514,"sku":"BWCS-HTB1200HB-3","price":99.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HTB1200HB-1.webp?v=1779581402","url":"https:\/\/batteryweb.com\/products\/compaq-presario-b1200-replacement-battery-144v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
