変化は有効であるが、最近の密閉形鉛電池では困難であ
るばかりか比重測定自体が多大の時間を要する問題があ
る。The reason that it is difficult to accurately perform the above-mentioned conventional life estimation is that a lead-acid battery for trickle or float use always has a voltage applied since the voltage is always applied. Deterioration state does not correspond. In addition, since the internal impedance measurement of the lead-acid storage battery is inherently low, especially the anode is lower than the cathode, so that the deterioration judgment is not largely changed and the judgment of deterioration is often seen. Although the specific gravity change is effective, it is difficult for recent sealed lead batteries, and the specific gravity measurement itself requires a lot of time.
