It replaces OEM part numbers BTR-8915 and BLI-994-8. Capacity is 5.92Wh — matched to the original cell specification for this handset.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCDM-8915 fitment:\u003c\/strong\u003e\n    The CDM8915 uses a single-cell 3.7V Li-ion pack with a dedicated connector keyed to this form factor. Both listed OEM part numbers share the same voltage rail and physical footprint — this cell fits both variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the cell through charge and discharge cycles on the CDM-8915 platform. The BMS accepted the charge controller handshake on the first cycle, and protection circuitry triggered correctly at low-voltage cutoff — no false trips under call or screen load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first install, disable any fast-charge mode and run one complete discharge-to-charge cycle. The phone's fuel gauge IC calibrates its coulomb counter against the new cell's discharge curve — skipping this step causes the percentage readout to drift or jump erratically for the first several days.\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 CDM-8915 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still running the discharge curve from the old, degraded cell. When the new cell hits a voltage point the old curve didn't map accurately, the OS reads a false zero and cuts power. The phone shuts down even though usable charge remains. One full discharge-to-charge cycle forces the coulomb counter to relearn the new cell's voltage-capacity curve, and the shutdowns stop. After calibration, the cell should hold voltage above 3.6V at the point the phone previously cut out.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone feels warm near the battery during the first charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh Li-ion cell has slightly higher internal impedance than a cell that has been cycled several times. The charge IC pushes current into that higher impedance, and the heat is a normal byproduct of the first cycle — not a fault. Warmth should stay moderate and reduce noticeably by the second charge. If the phone becomes hot to the touch or the charge IC shuts down mid-cycle, stop charging and check that the connector is fully seated — a partial connection forces the IC to work harder and raises current draw on the contact points.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405156876378,"sku":"BWCS-AU8915XL-1","price":23.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43405156909146,"sku":"BWCS-AU8915XL-2","price":26.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43405156941914,"sku":"BWCS-AU8915XL-3","price":28.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AU8915XL-big.webp?v=1779370315","url":"https:\/\/batteryweb.com\/products\/audiovox-cdm-8915-replacement-battery-37v-1600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
