It covers OEM part numbers TLi017C1 and TLi017D1. If your Jitterbug Flip dies faster than it used to or won't hold a charge through a normal day of calls and messaging, this is the swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eJitterbug Flip and Lively Flip platform:\u003c\/strong\u003e\n    Both the 4043SJ and 4053 chassis share the same battery bay dimensions, connector pinout, and BMS handshake protocol. That's why one cell covers all four model numbers — the fuel gauge IC and charge management logic are identical across the lineup.\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 a Jitterbug Flip unit. The BMS accepted the charge current without fault codes, and the protection circuit tripped correctly at the low-voltage cutoff threshold — no thermal events, no mid-cycle interruptions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after install:\u003c\/strong\u003e\n    After fitting this cell, let the phone discharge fully to auto-shutoff once before recharging to 100%. The fuel gauge IC is still calibrated to the old cell's discharge curve. One full cycle corrects the coulomb counter and stops the percentage reading from jumping around or cutting off early.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Jitterbug Flip shuts down suddenly at 20–30% after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Jitterbug Flip's fuel gauge IC stores a learned discharge curve from the original cell. A new cell with a slightly different internal resistance profile hits a voltage cliff earlier than the IC expects under modem or speaker load. When the terminal voltage drops below roughly 3.5V under that load spike, the BMS cuts power to protect the cell — even though the reported percentage still looks fine. One full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% lets the coulomb counter re-map to the new cell's actual curve, and the premature shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone feels warm near the battery compartment on the first few charges\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new li-ion cell typically has higher internal impedance than a broken-in one. During the first one to three charge cycles, the charge IC pushes current into that higher-impedance cell, and more energy converts to heat than it will once the cell settles. This is normal and temporary — surface temperature at the back panel should stay below 40°C. If the phone feels hot to the point of discomfort after the third full charge cycle, check that the replacement part number matches TLi017C1 or TLi017D1 before continuing use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392067174490,"sku":"BWCS-OTS406XL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392067207258,"sku":"BWCS-OTS406XL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392067240026,"sku":"BWCS-OTS406XL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OTS406XL-1.webp?v=1779143561","url":"https:\/\/batteryweb.com\/products\/greatcall-jitterbug-flip-replacement-battery-38v-1750mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
