Battery Life Calculator ( 3 Variant)

Basic Calculator

Battery Capacity

Load Current

Battery Life: -- hrs

Formula

\[ B_l = \frac{B_c}{I_l} \]

Where:
\(B_l\) = Battery lifetime (hrs)
\(B_c\) = Battery capacity (mAh)
\(I_l\) = Load current (mA)

Battery Capacity

Time Awake

Current Awake

Time Sleep

Current Sleep

Battery Life: -- hrs

Formula

\[ B_l = \frac{B_c}{\frac{I_a t_a}{t_a + t_s} + \frac{I_s t_s}{t_a + t_s}} \]

Where:
\(B_l\) = Battery lifetime (hrs)
\(B_c\) = Battery capacity (mAh)
\(I_a\) = Current when awake (mA)
\(I_s\) = Current in sleep mode (mA)
\(t_a\) = Time awake (s)
\(t_s\) = Time sleep (s)

Battery Life: -- hrs

Formula

\[ B_l = \frac{B_c}{\frac{I_s t_s}{T} + \frac{I_t t_t}{T} + \frac{I_c t_c}{T} + \frac{I_p t_p}{T}} \]
where \(T = t_s + t_t + t_c + t_p\)

Where:
\(B_l\) = Battery lifetime (hrs)
\(B_c\) = Battery capacity (mAh)
\(I_s, I_t, I_c, I_p\) = Currents (mA)
\(t_s, t_t, t_c, t_p\) = Time in each mode (s)
