Many companies using mobile computers turn to high-capacity batteries to lengthen per-charge run times. This typically extends sustained operating times to less than eight hours—still less than a work shift. A battery change-out would still be required to keep most mobile computers up and running.
Obtaining sufficient battery life to enable a mobile computer to run for a full shift (with a significant safety margin) demands intelligent power management in addition to high-capacity batteries. There are five components to intelligent power management. Their implementation impacts not only run time per charge, but also the useful life of mobile computer batteries and management of the battery replacement process.
