It fits the Professional 105CLB, 105EM, and 105GCB among others sharing the same battery bay. Dimensions are 38.02 × 38.00 × 5.65mm — verify these against your existing cell before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e105-series platform fit:\u003c\/strong\u003e\n    The Professional 105 line shares a common battery footprint across its variants. Same voltage rail, same connector orientation, same BMS handshake requirements — one cell covers the full 105 range listed in the compatibility data.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on 105-series hardware. The BMS accepted charge normally, voltage held steady at load, and cutoff thresholds triggered as expected at both ends of the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    On first use after installation, disable any fast-charge option for one complete discharge-charge cycle. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before high-current charging runs into an uncalibrated state estimation.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Professional 105 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC in the 105-series stores a learned discharge curve from the original cell. When you fit a new cell, that stored curve no longer matches real-world voltage behaviour. The OS reads an estimated state of charge from a model calibrated to a degraded or differently-aged cell, so percentages appear inflated or deflated. One full discharge to automatic shutdown followed by a full uninterrupted charge resets the coulomb counter and brings the gauge back in line.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops below the modem or display load threshold faster than the fuel gauge predicts — a voltage cliff the IC wasn't expecting. At 750mAh, the 105's cell is small, and transient current draw from radio activity or screen-on events can pull voltage down sharply. The BMS trips the output before the percentage counter reaches zero. Run one full calibration cycle and the IC adjusts its cutoff model; if shutdowns persist below 3.2V under load, the cell needs inspection.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409488085082,"sku":"BWCS-NK6PSL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409488117850,"sku":"BWCS-NK6PSL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409488150618,"sku":"BWCS-NK6PSL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NK6PSL-1.webp?v=1779579815","url":"https:\/\/batteryweb.com\/products\/mobiado-professional-105-damascus-replacement-battery-37v-750mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
