Battery level Indicator. Design Note 35


thumb
Usually we use a battery level indicator along with rechargeable battery to monitor the voltage level. If the Lead Acid battery is deeply discharged below a particular voltage level ,Memory effect develops and the battery never attains full charge later. So it is necessary to monitor the safe voltage level in the battery. A 12 volt Lead Acid battery shows 13.8 volts in fully charged condition and it should not deep discharge below 9 volts. If it happens, immediate charging is required to maintain the health of  battery.
