Kruger&Matz Live 2 Replacement Battery KM00231 3.8V 2200mAh

Kruger&Matz Live 2 / KM0410 — 3.8V Li-ion Replacement Battery (KM00231)

This is a 3.8V, 2200mAh Li-ion cell built to fit the Kruger&Matz Live 2, Live 2 LTE, KM0410, and KM0413 smartphones. It replaces OEM part numbers KM00231 and BL-5N-I. If your phone no longer holds charge, shuts down unexpectedly, or won't power on, this cell addresses the degraded original.

• Live 2 and Live 2 LTE compatibility: Both the standard Live 2 and the LTE variant share the same battery bay dimensions, connector pinout, and BMS handshake — 81.95 × 57.70 × 4.30mm physical footprint with identical voltage rail at 3.8V nominal.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the KM0410 platform. The BMS accepted the cell without triggering overcurrent cutoff, and the charge IC completed a full cycle to 4.2V without thermal events.
• Fuel gauge recalibration on first use: After installation, disable fast charging for the first complete discharge-charge cycle. The fuel gauge IC on these phones calibrates its coulomb counter against the cell's discharge curve — running a full slow cycle before high-current charging prevents the gauge from locking onto an inaccurate state-of-charge baseline.

Sudden shutdown at 20–30% on the Kruger&Matz Live 2 after a cell swap

This is a voltage cliff issue, not a faulty cell. When the modem fires a data burst or the screen brightness peaks, the instantaneous current draw pulls the cell voltage below the BMS cutoff threshold — even though the reported percentage suggests charge remains. A new cell has not yet had its internal resistance characterised by the fuel gauge IC, so the reported percentage and actual deliverable charge are misaligned. One full slow discharge-charge cycle lets the coulomb counter map the new cell's actual discharge curve. After that cycle, shutdowns at 20–30% typically stop.

Phone shows wrong battery percentage after replacement

The fuel gauge IC on the KM0410 and KM0413 stores a learned discharge curve from the old cell. When a new cell goes in, that stored curve no longer matches the actual cell chemistry state, so percentage readings jump or stall — commonly freezing near 50% or dropping from 30% to 0% with no warning. This is not a hardware fault. Drain the phone fully until it shuts off on its own, then charge uninterrupted to 100% without removing the charger. That single full cycle resets the coulomb counter reference points and restores accurate percentage reporting.
