It slots directly into the 968's battery bay and restores power to a phone that has seen capacity fade or a dead cell. Dimensions are 64.60 × 43.95 × 5.10mm — verify your bay size before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMTC 968 fit:\u003c\/strong\u003e\n    The 968 runs a single-cell 3.7V nominal rail. This cell matches that voltage and physical footprint. The connector pinout carries the thermistor line the phone's charge IC uses to monitor cell temperature during charging.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on a smartphone test rig. The BMS held charge termination correctly at 4.2V and did not trip the low-voltage cutoff prematurely under a simulated screen-plus-modem load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fast charge disable:\u003c\/strong\u003e\n    On first use after installation, turn off fast charging for one full discharge-charge cycle. This lets the fuel gauge IC recalibrate its coulomb counter against the new cell's discharge curve before high-current charging pushes into an uncalibrated cell.\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 968 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 968's fuel gauge IC stores a charge curve calibrated to the original cell. After a swap, the stored curve no longer matches the new cell's actual voltage-capacity relationship. When modem transmission or screen brightness spikes current draw, the cell voltage drops faster than the gauge expects — the phone reads 25% but the cell is already near cutoff. The fix is one complete discharge to auto-shutdown, then a full charge to 100% without interruption, which forces the coulomb counter to resync to the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMTC 968 not powering on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLithium-ion cells self-discharge in storage, and if a new cell drops below roughly 2.5V, the BMS enters lockout mode and blocks charging to prevent thermal runaway on a deeply discharged cell. The phone shows nothing on screen and appears completely dead. Connect the charger and leave it for 15–20 minutes without pressing the power button — the charge IC trickle-charges the cell back above the BMS re-enable threshold, typically around 2.8–3.0V. Once the phone shows a charging icon, normal charging can resume.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404337512538,"sku":"BWCS-OT995SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404337545306,"sku":"BWCS-OT995SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404337578074,"sku":"BWCS-OT995SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OT995SL-1.webp?v=1779369779","url":"https:\/\/batteryweb.com\/products\/mtc-968-replacement-battery-37v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
