It replaces the original cell when the factory pack loses capacity or stops holding a charge. The battery installs directly into the Code 01 chassis and connects to the existing BMS circuit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCode 01 compatibility:\u003c\/strong\u003e\n    The Code 01 uses a three-cell Li-Polymer arrangement at 11.55V nominal. Swapping a cell at a different voltage or connector pinout causes the BMS to reject charging. This battery matches the original voltage rail and connector to avoid that rejection.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through full charge and controlled discharge passes. The BMS held cell balancing within expected range and the protection circuit tripped correctly at low-voltage cutoff without a premature shutdown.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge until the laptop hibernates, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap.\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 after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BIOS stores historical charge data in EEPROM from the original cell. When a new cell arrives, that stored data no longer matches actual capacity, so the system flags health as poor or unknown. This is a data mismatch, not a battery fault. Running one full discharge-to-hibernate then a full uninterrupted charge forces the BIOS to rewrite the learn-cycle data against the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down abruptly at 20–30% battery shown\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still calibrated to the old cell's discharge curve. The gauge reads 25% remaining, but the actual cell voltage is already dropping below the BMS protection threshold under CPU and display load. The BMS cuts power to protect the cell before the OS can trigger a graceful shutdown. Run two full discharge-to-hibernate cycles back-to-back — this forces the fuel gauge IC to remap its voltage-to-percentage curve against the new cell, and the shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409521967194,"sku":"BWCS-MDX250NB-1","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409521999962,"sku":"BWCS-MDX250NB-2","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409522032730,"sku":"BWCS-MDX250NB-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MDX250NB-1.webp?v=1779579941","url":"https:\/\/batteryweb.com\/products\/mechrevo-code-01-replacement-battery-1155v-7800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
