Battery BM4Y Xiaomi Mi 11i / Poco F3 / RedMi K40 / K40 Pro

⚠️ Lithium-ion battery — for qualified professionals only
  • Before fitting: never install a battery that is swollen, punctured, deformed or without legible labelling.
  • Diagnose the device first: no new battery on a short-circuited, corroded or unrepaired board.
  • Exact reference only — a neighbouring model, even if it fits, is improper use.
  • After fitting: full supervised charge cycle and temperature check.
  • Swollen battery: do not ship it (ADR class 9 dangerous goods) — open an RMA with photographs.
  • Consumable: capacity loss through use and ageing is not a defect.
Full installation rules and liability regime — Schedule 3 of the GTCS
