Problem
Two batteries from the same nominal model have different health levels, causing unpredictable runtime between otherwise identical production days.
Solution
Root Cause / Diagnostic:
Li-ion batteries degrade at different rates based on storage temperatures, charge cycles, and manufacturing batches. Pairing an old degraded battery with a fresh pack leads to vastly different runtimes, catching camera operators off guard.
Actionable Fix:
1. Label every battery with unique serial numbers and purchase dates; track battery health percentages using intelligent smart chargers.
2. Group batteries into matched production pairs with comparable internal resistance and cycle counts.
3. Retire batteries whose maximum capacity has dropped below 80% of original nominal watt-hour ratings.
Pro Tip:
Use numbered colored tape bands on batteries: green for fully charged and tested, red for discharged, and yellow for degraded backup packs.
