Unfortunately it is generally not possible to measure static electricity with a multimeter because the input impedance is too low.

Voltage and internal resistance do not correlate with capacity and fail to predict the end of battery life effectively, especially with Li-ion and lead acid systems. The truth lies in the chemical battery. A digital measurement alone is subject to failure because the chemical symptoms are not represented.
Accurate measurement of battery charge and capacity is essential for ensuring reliability, longevity, and efficiency. Mismanagement of batteries can lead to shortened lifespans, unexpected downtimes, and higher operational costs.
Battery charge, also known as the state of charge (SoC), indicates the current energy level in the battery compared to its full capacity. It is typically expressed as a percentage and helps determine how much longer a battery can operate before needing a recharge.
