Sonstige Equinux tizi Mobile TV 3.7V 1000mAh Compatible Battery

Sonstige Equinux tizi Mobile TV — 3.7V Li-ion Replacement Battery

This 3.7V, 1000mAh Li-ion cell replaces the original battery in the Equinux tizi Mobile TV, a compact handheld digital television receiver. 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.

• Equinux tizi Mobile TV fitment: 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.
• Bench tested on actual hardware: 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.
• Fuel gauge recalibration after swap: 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.

Why the tizi shuts down suddenly before the battery reads empty

The 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.

Battery percentage jumping or freezing after cell replacement

The 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.
