hi,
can i have safe battery backup ? I am using 6v 5ah battery as standby source. in my power supply circuit i have lm7808 and diode resistor and battery and lm2931 to get 5v constant output.
am attaching the schematic.
What happens if the power goes off for 2 days. Will the system start immediatel or how much time it ll take to start properly.
can any thing be done to this circuit such that even when the battery is flushed out completely, it doesnt pull the supply for long. the systems starts smoothly.
regards
