The leakage current of a battery can be measured by the battery test equipment. However, existing battery simulators are not accurate for small capacity Lithium coin batteries (such as 10 μA measurement accuracy in the dynamic model battery simulator of Keithley 2281S).
Therefore the leakage current of the Lithium coin battery should be acquired in μA level to precisely estimate the state of charge (SOC) of the battery for utmost using harvested energy in indoor applications. The leakage current of a battery can be measured by the battery test equipment.

The average leakage current generated during a 4.6 V (vs. Li/Li +) potentiostatic hold at 45°C with a 90:5:5 (LiNi 0.5 Mn 0.3 Co 0.2 O 2 :C45:PVDF binder) positive electrode a graphite negative electrode in coin cells. In red the coin cell had two Celgard 2325 separators and in blue the coin cell had only one Celgard 2325 separator.
An experimental method to measure leakage current by applying a known charge current in μAs to a stabilized post-charge battery to observe the sign of the battery terminal voltage change is proposed. When the applied charge current is larger than the leakage current, a positive sign (terminal voltage increase) can be observed.
A precise leakage current measurement procedure has been proposed as a successive approximation search algorithm , where the measurement period and the number of iteration are pre-determined constants. The charge current is adjusted [1 − sign × (½) n] times for each search procedure.
