池の周囲温度による寿命の変化特性を折線で近似
して記憶させるＲＯＭと、密閉形鉛蓄電池の周囲
温度を検出する温度センサーとを有し、前記温度
センサーによつてその周囲温度を検出し、該温度
における寿命の変化特性に対応したパルスを前記
ＲＯＭから出力させ、前記パルスをカウントし、
該カウント数が一定値に達するごとに表示信号を
送出するとともに該カウント数が所定値に達した
時に音声による寿命予告信号を送出するカウンタ
ー部を備えたことを特徴とする電源装置。 The battery includes: a ROM that stores an approximation by a broken line of the characteristic of change in the life of a sealed lead-acid battery due to ambient temperature of a sealed lead-acid battery that is charged with a constant floating charging voltage; and a temperature sensor that detects the ambient temperature of the sealed lead-acid battery; Detecting the ambient temperature with a temperature sensor, causing the ROM to output pulses corresponding to the change characteristics of the life at the temperature, and counting the pulses;
A power supply device comprising a counter section that sends out a display signal every time the count number reaches a predetermined value, and sends out an audio service life notice signal when the count number reaches a predetermined value.
