| Feb 2, 2016 at 12:56 | comment | added | RJR | @NaveenRaja correct - in new batteries it isn't a problem (doesn't mean it doesn't happen), but generally a newer battery will have enough charge in even cold weather to start the engine. Once started there's no issue obviously as the alternator will provide power. | |
| Feb 2, 2016 at 12:20 | comment | added | jms | @NaveenRaja The State of Charge (SoC) of a battery is the amount of electric charge (Ah) stored at some point in time compared to the total charge capacity. A half discharged battery would have a SoC of 50%. The maximum current draw is mostly independent from the state of charge, being limited by the internal resistance. The maximum current draw is measured in Amperes (A) if that is what you ask. | |

| Feb 2, 2016 at 11:55 | comment | added | RJR | to answer your question "how is this solved?". In colder countries there are a lot of roadside assistance companies that help jump-starting cars with aging batteries in cold weather. In other words - it's not solved... | |
| Feb 2, 2016 at 11:49 | comment | added | jms | @NaveenRaja The electric charge capacity of a battery is usually measured in Ampere-hours (Ah), and it determines what current you have to draw from a full battery in order to discharge it in one hour. The energy capacity of a battery is measured in Watt-hours and is equal to the electric charge multiplied by the nominal voltage. The nominal voltage of the common car battery is 12V, so a 50Ah car battery would have an energy capacity of 600Wh. How much current you can draw is completely distinct from the capacity, and that value falls with temperature. | |
