Battery Performance – Charge Times -
Reconditioning
The following information is intended to provide an overview on the battery-driven
system operation times and charging intervals for the Z-PAK battery pack. There are a
number of variables that impact both the operating time and charge time, that must be
taken into consideration when anticipating the performance of a specific battery.
Cart battery packs are "consumable" items, and as such should be expected to have a
gradual drop-off in performance (system operating time) over their life span. The
system operating time numbers listed in this document are in reference to a "new"
(optimum) battery.
Charging times will be significantly impacted by the temperature of the battery pack at
the time of the start of the charging cycle. The intelligent PIC device that manages the
charging process will disable, or reduce the rate of charge, as dictated by the battery
pack's current temperature.
The total time that will be required for a battery to reach a full state of charge is
impacted by a number of variables. These include:
1) Operating state of system (transducer in use: HV active)
2) Temperature of battery pack
3) Initial first-charge for Z-PAK:
Cart Battery Pack
Performance:
Typical system operation interval (on full charge): .......................... up to 1.5 Hours
Charging:
Rapid Charge Rate (5A): ................................................................. 5.0 hours (total)
Step #1: .......................................................................................... 3.0 hours – main
charge
Step #2: .......................................................................................... 2.0 hours – final
top-off charge
Trickle-Charge Rate (i.e., hot battery state) .................................... 16.0 Hours (worst-
case)
Recondition & Full Charge State:
Optimum (battery in cool state, and initial charge level near full) .... 8.0 Hours (total)
