It slots into the original battery compartment and connects to the same contact points as the factory cell. No OEM part number is listed for this unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDroid Bionic platform fit:\u003c\/strong\u003e\n    The Bionic uses a removable single-cell 3.7V pack with a three-contact interface feeding both the charge IC and the fuel gauge IC. This cell matches that voltage rail and contact layout, so the phone's power management hardware reads it without modification.\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 Bionic platform and confirmed the BMS handshake completes without error. The charge IC accepted the cell and moved through trickle, CC, and CV phases correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installing this cell, disable fast charging and run one full discharge down to automatic shutdown, then charge uninterrupted to 100%. The fuel gauge IC on the Bionic calibrates its coulomb counter against that first full cycle — skipping it causes erratic percentage readings early on.\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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Droid Bionic's modem draws a sharp current spike when switching between LTE and 3G bands. A new cell with an uncalibrated fuel gauge IC may report 25% remaining while the actual resting voltage is already near the BMS low-voltage cutoff. When the modem spike hits, the instantaneous voltage drop crosses the cutoff threshold and the BMS disconnects the cell — the phone shuts off hard. One complete discharge-charge cycle lets the coulomb counter map the actual discharge curve of the new cell, and the shutdowns stop. After calibration, cutoff should align closer to 3.0V under load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone warm near the battery compartment during the first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell starts with higher internal impedance than a broken-in cell. The Bionic's charge IC pushes the same charge current regardless, and higher impedance means more heat dissipated in the cell during the constant-current phase. This is normal on cycle one and two and settles as the cell conditions. If the back cover is hot to the touch rather than warm, remove the charger and let the phone cool — then restart charging. By the third full cycle, surface temperature during charging should drop noticeably.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405092028506,"sku":"BWCS-MOB860SL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405092061274,"sku":"BWCS-MOB860SL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405092094042,"sku":"BWCS-MOB860SL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MOB860SL-1.webp?v=1779369970","url":"https:\/\/batteryweb.com\/products\/verizon-bionic-4g-lte-replacement-battery-37v-1550mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
