It fits directly into the tizi chassis and restores power to the device when the original cell can no longer hold charge. Dimensions are 53.00 x 33.90 x 5.70mm — verify against your existing cell before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEquinux tizi Mobile TV fitment:\u003c\/strong\u003e\n    The tizi runs a single-cell 3.7V Li-ion pack tied directly to the receiver board's power rail. This cell matches that voltage rail and physical footprint, so the board sees the same nominal supply it expects.\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 passes and confirmed the BMS trips correctly at both the high and low voltage cutoffs — no runaway charge, no hard undervoltage lockout under normal draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    After installing a new cell, run one complete discharge down to the device's auto-shutoff, then charge uninterrupted to 100%. This lets the fuel gauge IC map its charge curve against the new cell rather than the degraded profile it stored from the old one.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the tizi shuts down suddenly before the battery reads empty\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe tizi receiver draws a burst of current whenever the tuner locks onto a signal or refreshes the display. An aged cell cannot sustain voltage under that brief load spike, so voltage drops sharply and the protection circuit cuts power — even when the charge indicator still shows 20–30%. A new cell with intact capacity handles the same current demand without the voltage cliff. After fitting this replacement, run one full discharge-charge cycle so the fuel gauge recalibrates and the shutdown threshold aligns to the new cell's actual discharge curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping or freezing after cell replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe tizi's fuel gauge IC stores a discharge model calibrated to the original cell's internal resistance and capacity. Swapping to a new cell immediately creates a mismatch — the gauge feeds the display a number based on the old profile, so readings jump, freeze, or read 100% long after the cell is partially drained. This is not a fault with the replacement cell. Force a full recalibration: discharge the device completely until it powers off on its own, then charge straight to 100% without interrupting. After that single cycle, the gauge reads against the correct curve and percentage reports stabilise.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409496211546,"sku":"BWCS-NK5CMX-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409496244314,"sku":"BWCS-NK5CMX-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409496277082,"sku":"BWCS-NK5CMX-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NK5CMX-1.webp?v=1779579814","url":"https:\/\/batteryweb.com\/products\/sonstige-equinux-tizi-mobile-tv-replacement-battery-37v-1000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
