The Voxtel M320 is a compact early-2000s handset with a slim battery bay — dimensions are 50.00 × 38.00 × 4.80mm, matching the original cell footprint. When the original cell degrades and the phone starts shutting down unexpectedly or won't hold a charge, this replacement restores normal operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVoxtel M320 fit:\u003c\/strong\u003e\n    The M320 uses a slim single-cell Li-ion pack with a low-current charge circuit typical of early-2000s GSM handsets. The connector orientation and cell thickness are matched to the original battery tray — no case modification needed.\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 the bench, confirming the BMS holds cutoff correctly at the low-voltage threshold and that the charge IC accepts the cell without triggering a fault condition.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    After fitting this replacement, run one complete discharge down to automatic shutdown, then charge uninterrupted to 100% before normal use. The Voxtel M320's fuel gauge IC was calibrated to the original cell's discharge curve — skipping this step leaves the percentage readout inaccurate for the first several cycles.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Voxtel M320 shuts down suddenly at 20–30% battery remaining\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAn aged Li-ion cell develops higher internal resistance. Under the load of a GSM transmit burst — even a brief call connection — terminal voltage drops sharply below what the phone's protection circuit considers safe. The phone reads this voltage dip as a near-empty cell and cuts power immediately, even though the fuel gauge shows 20–30% remaining. Replacing the cell eliminates the resistance problem, but the fuel gauge will still misread until it completes one full calibration cycle from 100% charge to shutdown.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone shows incorrect battery percentage after fitting the new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Voxtel M320's fuel gauge IC stores a discharge model built on the old cell's behaviour — it has no automatic way to detect a new cell was installed. Until recalibrated, percentage readouts will jump or plateau at values that don't match actual capacity. Run one full discharge to auto-shutdown, then charge to 100% without interruption. After that cycle, the fuel gauge resets its internal reference points against the new cell's actual discharge curve and percentage accuracy stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404167020634,"sku":"BWCS-BLS210SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404167053402,"sku":"BWCS-BLS210SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404167086170,"sku":"BWCS-BLS210SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BLS210SL-1.webp?v=1779369251","url":"https:\/\/batteryweb.com\/products\/aeg-voxtel-m320-replacement-battery-37v-800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
