It fits the Neo's battery bay directly and connects to the phone's charge and fuel gauge circuitry via the standard flex connector. Voltage and capacity match the OEM specification for this handset.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMTC Neo fit:\u003c\/strong\u003e\n    The Neo runs a single-cell 3.7V Li-ion architecture. This cell matches that voltage rail, physical footprint (65.23 × 41.98 × 5.21mm), and the connector orientation the Neo's BMS expects. No modifications 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, watching BMS handshake, cutoff voltage behaviour, and charge IC response at low state-of-charge. The cell accepted charge from 0% and held the full 1500mAh curve without BMS trip events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first installation, disable fast charging and run one complete discharge-to-charge cycle at standard rate. This gives the Neo's fuel gauge IC time to map the new cell's discharge curve before high-current charging pushes current 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\"\u003eSudden shutdown at 20–30% on the MTC Neo after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still reading the old cell's discharge curve. The new cell hits a voltage cliff — typically around 3.5V under modem or display load — before the gauge reads zero. The phone interprets this as a normal operating voltage and keeps running until the cell can no longer sustain the current draw. One full discharge-charge cycle at standard rate forces the coulomb counter to resync against the actual cell capacity and cutoff point.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMTC Neo not powering on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage. If this cell dropped below 2.5V per cell while sitting unused, the BMS enters lockout mode to prevent damage — and the phone won't respond to the power button. Connect the phone to a wall charger (not a PC USB port) and leave it for 15–20 minutes without pressing anything. The charge IC will trickle current into the cell until voltage climbs above the BMS re-initialisation threshold, after which normal charging resumes. If the charging indicator does not appear after 30 minutes, check that the wall adapter is delivering at least 5V 1A.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405131415642,"sku":"BWCS-HU8220SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405131448410,"sku":"BWCS-HU8220SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405131481178,"sku":"BWCS-HU8220SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HU8220SL-1.webp?v=1779369992","url":"https:\/\/batteryweb.com\/products\/mtc-neo-replacement-battery-37v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
