The only way to do that with a voltage meter is outlined in my last post.
If you are out and about in a tear waiting 12 hours to check state of charge is a non starter.
That said you can with experience gain a little insight to the batteries condition.
Lets say that under a proper full charge test as outlined in last post that 12.8 is fully charged then 12.3 is 50% (roughly speaking)
If under load the meter is showing 12.2 ish switch all loads of for 10 mins and then measure it should recover enough to give you a clue say it goes up to 12.4 in that time then you have some usage left yet.
Supremely accurate? no, but an indication and better than most battery abusers do.
