2. Ready Figure 62 Increase of impedance showing aging of batteries and defects Generally the overall Impedance of your accumulators should not increase more than 5 per year if you keep it in a controlled climate and with an ideal charger If temperature is not stable many discharges or false charging operations occurred than this increase will be faster and your battery life will be shortened Generally the impedance curve in BACS should show an almost horizontal line so you should not see any major change for 90 of the battery life unless there is a problem In the picture above you can see that accumulators which are OK do not show any significant increase while others do have this effect and rise faster than the others The absolutely measuring value numeric value RI in milliohm does not describe the state of an accumulator directly Because the manufacturers of the accumulators are measuring the RI with different measuring devices the values are comparable only if identical measuring devices were used and the environmental data temperature accumulator voltage were the same Since this is almost never the case the absolutely measuring values in milliohm which are determined from BACS are not always comparable with the data from the manufacturer Exception The HIOKI measuring device Battery Hightester model 3554 determines almost identical measuring results at correct handling like BACS but these models only O
