Tracfone One Touch Pixi Glitz Compatible Battery 3.7V 1450mAh

Tracfone One Touch Pixi Glitz A463 / A463BG — 3.7V Li-ion Replacement Battery

This is a 3.7V, 1450mAh Li-ion cell for the Tracfone One Touch Pixi Glitz and One Touch Pixi Glitz 4G (models A463 and A463BG). It replaces the original battery when the phone no longer holds a charge or fails to power on. No OEM part number is published for this cell — fitment is confirmed by voltage, capacity, and physical dimensions (64.25 × 49.88 × 4.20mm).

• A463 and A463BG compatibility: Both the standard and 4G variants of the Pixi Glitz share the same battery bay dimensions, voltage rail, and connector pinout. One cell fits both without modification.
• Bench tested on actual hardware: We cycled this cell through a full discharge and charge sequence on the A463 platform. The charge IC accepted the cell without fault codes, and the BMS handed off correctly to the phone's charge controller at top-of-charge.
• Fuel gauge recalibration on first use: After installing this cell, disable any fast-charge accessory and run one complete discharge-to-charge cycle at standard current. The fuel gauge IC on the Pixi Glitz calibrates its discharge curve on first use — skipping this step causes erratic percentage readings for the first several cycles.

Why the Pixi Glitz reports wrong battery percentage after a cell swap

The Pixi Glitz uses a basic fuel gauge IC that stores a discharge curve based on the previous cell's internal resistance and capacity fade profile. When you install a new 1450mAh cell, the IC still references the old curve, so the percentage readout is wrong from the start. This typically shows as the phone jumping from 40% to 5% with no warning, or holding at 100% long after charging stops. One full slow-charge cycle — charge to 100%, drain to auto-shutdown, charge again — forces the IC to rebuild its reference curve against the new cell.

Sudden shutdown at 20–30% on the Pixi Glitz after replacement

This shutdown pattern points to a voltage cliff, not a capacity problem. Under the combined load of the modem radio and screen, the cell voltage drops sharply — the BMS reads this as a low-voltage fault and cuts output to protect the cell, even though the gauge still shows charge remaining. It is common on the first two cycles of a new Li-ion cell before the electrolyte fully wets the electrode stack. Let the phone complete two full discharge-charge cycles and the cutoff point will stabilise. If shutdowns persist past cycle three, check that resting cell voltage reads at least 3.6V with a multimeter before installation.
