I drained by accident my car's battery. When I connect it now to a multimeter it shows 3V. I connected the battery already to a trickle charger and I would like to know for how long I should charge it, so that I don't damage it by overcharging. E.g. can I measure with my multimeter a voltage or current level reached and then know that I have to stop the charging? Also, can I use my multimeter to calculate in advance the charging time? Tnx

Quantities I know:
- The trickle charger's output is 13.0V and 10A
- the dead car battery showed 3.0V before charging
- the battery has a capacity of 60Ah

**EDIT:** I made a mistake with measuring the current of the charger. The right current (or at least the one stated on the charger itself) is not 0.3A, but 10A
