It slots into the original battery bay and connects to the same charge controller the factory cell used. Capacity is drawn from product data, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMini 210 and CQ20 compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, connector pinout, and charge controller handshake. A single cell spec covers both — the BMS talks to the same BIOS charge circuit across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on the Mini 210 platform and confirmed the BMS completed the BIOS handshake without fault codes. Charge acceptance ran cleanly from depleted to full across three consecutive cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle conditioning on the Mini 210:\u003c\/strong\u003e\n    After installation, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after swapping cells 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 battery health as poor immediately after swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Mini 210 BIOS reads health data stored in the old cell's EEPROM and carries that reading forward when a new cell is first installed. The new cell has not yet completed a learn cycle, so the BIOS has no fresh calibration data to display. This shows up as \"poor health,\" \"unknown,\" or a mismatched Wh rating in system info — none of which reflect the actual condition of the new cell. Run a full discharge-to-hibernate then a full uninterrupted charge to let the fuel gauge IC write new calibration data to the BIOS.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNetbook shutting down at 20–30% charge shown on screen\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 voltage curve. The displayed percentage lags the real state of charge, so the system hits the low-voltage cutoff while the gauge still reads 20–30%. It is not a fault with the cell — it is a calibration gap. Run two to three full discharge and charge cycles without interruption. After the third cycle, the gauge reading and actual cell voltage should align within a few percent.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410814271578,"sku":"BWCS-HPM210NB-1","price":52.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410814304346,"sku":"BWCS-HPM210NB-2","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410814337114,"sku":"BWCS-HPM210NB-3","price":68.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPM210NB-1.webp?v=1779581211","url":"https:\/\/batteryweb.com\/products\/compaq-mini-210-replacement-battery-108v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
