CHART A
Independent Laboratory Testing BCI 2-Hour Life
Group Size “27” Batteries East Penn Gel and AGM vs. Competitor
This chart compares the cycles run until the battery capacity dropped to 50% of
the 15th cycle’s capacity (on discharges at the 2-hour rate to a 10.5-volt cutoff).
CHART B
Charging Current vs.Charging Time
Shown is the current needed to charge a battery from 0% to 90% state of charge
in a given time. Or time required to change a battery from 0% to 90% state
of charge at a given current. For example, to charge an 8G8D (curve H) to 90% in
3.5 hours, 100 amperes are required; at 35 amperes, it would take 10 hours
