It fits the Nuvifone M10, M10E, and A10 — a GPS-integrated smartphone platform that combines active navigation with standard voice and data functions. Voltage and connector match the original spec exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eM10, M10E, and A10 compatibility:\u003c\/strong\u003e\n    All three models share the same battery bay geometry, 3.7V nominal rail, and contact layout. The SBP-23 part number covers the full platform. No adapter or modification needed — the connector seats the same way across all three variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the M10 platform. The BMS accepted charge from the device's internal charge IC without tripping overcurrent protection, and the fuel gauge IC began tracking the new cell's discharge curve from the first cycle onward.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installing this cell, disable any fast-charge mode and run one complete discharge-charge cycle before normal use. The M10's fuel gauge IC holds the old cell's discharge curve in memory. One full cycle lets it recalibrate against the new cell before high-current charging starts pushing into an uncalibrated state.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Nuvifone M10 shuts down suddenly at 20–30% charge remaining\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe M10 runs a GPS receiver and modem stack simultaneously — both spike current draw well above idle levels. An aged or degraded cell may show 25% state-of-charge on screen but cannot sustain voltage under that combined load. When the cell voltage drops below the BMS cutoff threshold during a load spike, the phone shuts off immediately regardless of what the percentage indicator shows. This is a cell-level voltage cliff, not a firmware bug. Replacing the cell resolves it — a fresh cell at 1200mAh capacity holds its voltage rail stable through those draw spikes.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the Nuvifone M10 sat unused for several months, the cell voltage may have dropped below 2.5V — the point where the BMS enters lockout to prevent damage. In lockout, the phone shows nothing on screen and appears completely dead. Connect it to a charger and leave it for 20–30 minutes without attempting to power it on. The charge IC will trickle current into the cell at a safe rate until voltage climbs above the BMS recovery threshold, typically around 2.9V, at which point normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405123223642,"sku":"BWCS-GAM10SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405123256410,"sku":"BWCS-GAM10SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405123289178,"sku":"BWCS-GAM10SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GAM10SL-1.webp?v=1779369992","url":"https:\/\/batteryweb.com\/products\/garmin-asus-nuvifone-m10-replacement-battery-37v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
