BatteryMark BatteryMark uses a combination of hardware and software to measure the battery life of notebook computers under real-world conditions (the hardware used in BatteryMark is the same ZDigit II device required by version 1.0). BatteryMark exercises a different bit software workload engines for processor, disk, and graphics tasks. BatteryMark mixes these workloads together and adds periodic breaks in the work that reflect the way users pause while working. BatteryMark 2.0 works with Advanced Power Management (APM) under Windows 95.
