⚠️ 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.
