Measurement of lead-acid battery internalresistance in charging mode

Method and the resultsof measurementof the internalresistance ofbattery duringitschargeanddischarge are described.It was establishedthat the internal resistance ofthe batteryin operatingvoltage range is almost equallywhencharging and dischargingand does not dependon the current.
