Hello and thanks for great site!
i have a 6 volts,12ah lead acid battery which it's state of charge(soc) at 100% is 6.37 volts
in other hand, i have a circuit that runs with 5 volts and it's current consumption is 100ma
by connecting this circuit to the battery, how can i calculate after one hour, how much battery voltage will be ?
any help would be greatly appreciated

 

hi ms,
Welcome to AAC
The usual way is to check the graphs for that type of battery.
This image is for a 12v SLA, just divide the Voltage by 2.

The plots are for a battery in new/good condition.

BTW: you should not connect a 6V bty directly to a 5v circuit.

 

Thank you for your reply,
yes, i use diodes or regulator for keeping circuit voltage on 5 volts
now i have another question
is it right to say that due to circuit current consumption value(100ma), after one hour battery current will be 11.99?(12-0.1)?
and if this is true, can we divide 11.99 to 12, (11.99/12=99%) to get battery charge percent after one hour?
