Z55H 3.85V Rechargeable Lithium-ion Coin Cell
The original Zenipower Z55H batteries in this model suffer from premature electrochemical breakdown, often caused by firmware-induced thermal runaway during charging. This degradation increases the cell's internal resistance, leading to rapid voltage sag and the symptom of the battery 'draining' within minutes. Replacing the individual coin cell restores the energy density required for the earbuds to maintain long-term power stability.
