sla discharge curve
I have a circuit that will be powered by a 12v SLA battery. One of the chips in the circuit requires a regulated 12v supply. I know that the battery puts out about 14v when fully charged. I intend to use a LDO regulator for the 12v which will continue to operate as long as the input voltage is above 12.5v. What I would like to know is: how long can I reasonably expect the battery to continue to put out a voltage above 12.5v? What does the discharge curve of voltage over time look like for a SLA battery? Would it be smarter to use some kind of DC-to-DC converter to supply the 12v? If so, are there any inexpensive ones available?
Thanks in advance.
