Battery Runtime Tips & Best Practices
Accurate Load Calculation
For accurate runtime calculations, measure actual device current consumption under real-world conditions. Manufacturer specifications may not reflect actual usage patterns or environmental factors.
Temperature Effects
Battery runtime decreases significantly in cold temperatures. Plan for 20-50% reduced runtime in cold conditions, and consider battery heating for critical applications in extreme cold.
Aging Considerations
Account for battery aging in long-term planning. Battery capacity typically decreases by 20% after 500-1000 cycles depending on chemistry. Regular capacity testing helps track degradation.
