Note: Run times are typical at 25°C (77°F). Add the values given in the "10 plus adder" column to the values given in
the "10" column for each Battery pack installed above a total of 10. Example: When 13 Battery packs are installed, the
recharge time is typically less than 24 + 2.4 + 2.4 + 2.4 = 31.2 hrs. The run time for this system at full load is typically
greater than 4.0 + 0.5 + 0.5 + 0.5 = 5.5 hrs.
