What amount of current should I use to charge a 12V car battery?
Another problem is that without current limiting a discharged battery may initially draw too much current out of the power supply, Your battery capacity is 80Ah, C/10=8A <= 10A, then maximum charging current is 8A. If capacity is 150Ah, C/10=15A > 10A, then stick with maximum 10A for charging current. Share. Cite. Follow

Common AGM Battery Limits: – Maximum discharge current – Maximum charging current – Recommendations from
multimeter
If the current is too high it will blow the fuse on the multimeter, or blow up the battery. Wikipedia says the Energiser AA battery has an internal resistance of about 0.15R at room temperature. This gives around 10A current. However, the internal resistance of the multimeter may now have an effect, reducing the current.

Maximum current draw from 12v sealed lead acid battery?
Even at 8A, the battery will be flat after half an hour. And be aware that lead-acid batteries don''t like being left flat. Once run down, they should be recharged as soon as possible, or they may be permanently damaged. *1C is a current numerically equal to the amp-hour rating of a battery. So for an 8Ah battery, 1C is 8A.
