- | For other than C/20 loads((flooded)): | + | Because of the Peukert effect, lead bank //measured// capacities are strongly affected by dicharge rate. Sample data below is for flooded lead acid.((Due to lower internal resistance AGM is less affected by discharge rate and lithium is barely affected at all.)) C/20 capacity is multiplied by the factor below to find projected capacity at given discharge rates. |
