A cheap battery holder cost me 3 weeks #Shorts

Description

Nearly three weeks of discharge data compromised by an unlikely culprit: the battery holder. A cell showed 1.5V at rest but collapsed to ~0.5V under load, not a bad battery, but a cheap holder bleeding power across the connection. The fix: redesigning the fixture for clean, consistent contact.
