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.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLive 2 and Live 2 LTE compatibility:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the Kruger\u0026amp;Matz Live 2 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis 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.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone shows wrong battery percentage after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 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.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392098009178,"sku":"BWCS-KMZ410SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392098041946,"sku":"BWCS-KMZ410SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392098074714,"sku":"BWCS-KMZ410SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KMZ410SL-1.webp?v=1779143748","url":"https:\/\/batteryweb.com\/products\/krugermatz-live-2-replacement-battery-38v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
