BLU Life Max C946504365L Replacement Battery 3.8V 2950mAh

BLU Life Max L0110UU / L0110EE — 3.8V Li-Polymer Replacement Battery (C946504365L)

This 3.8V Li-Polymer cell replaces part number C946504365L in the BLU Life Max smartphone (models L0110UU and L0110EE). Capacity is 2950mAh (11.21Wh), matching the original cell specification. It restores calling, messaging, and app performance lost to a degraded original battery.

• Life Max L0110UU and L0110EE compatibility: Both model variants share the same battery bay geometry, connector pinout, and BMS handshake protocol — one cell covers both. The 94.90 × 65.80 × 4.14mm footprint fits the housing without modification.
• Bench tested on actual hardware: We ran this cell through charge, load, and BMS communication checks on the Life Max platform. The BMS handshake authenticated correctly and protection cutoffs triggered at expected thresholds under both low and high draw.
• Fuel gauge recalibration on first use: On first install, disable fast charging and run one full discharge-to-charge cycle before re-enabling it. The fuel gauge IC in the Life Max calibrates its coulomb counter against the cell's discharge curve — skipping this step lets the IC push fast-charge current into an uncalibrated cell, which can cause early charge termination.

Sudden shutdown at 20–30% on the Life Max after a cell swap

This is a voltage cliff problem, not a capacity problem. The Life Max's modem and display together draw enough current that a new, uncalibrated cell can sag below the BMS cutoff voltage before the OS reads 0%. The fuel gauge IC still holds an old discharge curve in memory from the previous cell. One complete discharge-charge cycle rewrites that curve to match the new cell, and the shutdowns stop. If shutdowns continue past two full cycles, check that cell voltage at rest is above 3.7V — below that, the cell may have been over-discharged in storage.

BLU Life Max not powering on after sitting in storage with the new battery installed

Li-Polymer cells shipped at storage charge (roughly 3.6–3.8V) can drop below 2.5V per cell if left unpowered for weeks inside the device — the phone's standby draw continues even with the screen off. Below 2.5V, the BMS locks out to prevent cell damage and the phone will not respond to the power button. Connect the phone to a wall charger — not a USB port — and leave it for 20–30 minutes before pressing power. If the charge IC detects a recoverable voltage, it will trickle-charge the cell back above the BMS unlock threshold, which sits at approximately 2.8V on this platform.
