Lithium-Ion Replacement Battery
The electrolyte within the lithium-ion cells has decomposed into gas due to prolonged exposure to high heat and constant high-voltage states (overcharging). This expansion is a chemical failure that cannot be reversed and compromises the internal separators, creating a risk of thermal runaway. Replacing the battery assembly is the only safe and effective repair for this failure mode.
