Multiple-Program Longevity Worksheet
Quick Method:
If multiple programs are routinely used, determine the battery-longevity projection for each program using the methods mentioned
above (including the 'Multiple-Area Battery-Longevity Worksheet' if needed). The battery-longevity projections for multiple programs
should be between the longest and shortest projections.
Detailed Method:
For a more specific estimate, one can calculate the time-weighted-average battery-longevity projection as follows:
1. Determine the battery-longevity projection for each program and estimate the number of hours per day of use for each program.
2. For each program multiply the expected battery longevity by the number of hours of use per day and then divide the result by 24.
Battery longevity program 1____ x ____ hours per day / 24 = _____
Battery longevity program 2____ x ____ hours per day / 24 = _____
Battery longevity program 3____ x ____ hours per day / 24 = _____
Battery longevity program 4____ x ____ hours per day / 24 = _____
3. Total the results:
This total is the battery-longevity projection for the multiple programs.
= _____
