Enter values then press Calculate.

How we calculate

We add the usage values (in A) from your selections to get average current.

Battery Life
Device usage(mA) + Uplink (mA) + Role (mA) + Nodes Seen (mA) = Power_Usage
totalHours = battery_size / Power_Usage
Battery in days = totalHours / 24 (round down to the nearest whole day, hour and minutes)
