Recommended Depth of Discharge by Battery Type

Battery Type Recommended DoD Maximum DoD Cycle Life at 80% DoD
Lithium-ion 80% 100% 2000-5000 cycles
Lead Acid 50% 80% 300-1000 cycles
Gel 50% 80% 500-1500 cycles
AGM 50% 80% 500-1500 cycles

Understanding Depth of Discharge

  • DoD is the percentage of battery capacity that has been discharged
  • Higher DoD reduces battery lifespan
  • Regular deep discharges can significantly shorten battery life
  • Keep DoD within recommended ranges for optimal performance
  • Consider temperature effects on battery performance

Tips for Battery Longevity

  • Stay within recommended DoD limits
  • Maintain proper charging practices
  • Keep batteries at moderate temperatures
  • Regular maintenance and monitoring
  • Use appropriate charging equipment
