To know how many amps your battery can output, you have to know two things about it – the terminal voltage of the battery in comparison to the ambient or “mating” voltage and its internal impedance.
to get a rough estimate, use this formula: ((when car is running/charging )* (miles traveled) * (1.6)) / (hours driven) = watt-hours = ah x hrs driving = days worth of driving). this will be an approximate number and it may not account for things like cold conditions because we don't yet have a set number for cold weather.
how many amps are in a 12-volt car battery?
it depends. most cars have either a 6-volt or a 12-volt system, but the amps will vary from one to the other. a 6-volt system usually has a battery with a capacity of 55 – 66 amp hours while a 12-volt car battery can hold between 27 and 60 amp hours. and you always want to make sure it's charged up!
a full charge should give your car enough power for about 20 miles, though if you're going on long trips, don't forget your jumper cables to help give you that extra oomph in case things go wrong. nowadays, people rely much more on hybrid vehicles which use both gas and electric engines to run, picking up their energy from
how many amps is a fully charged car battery?
a fully-charged car battery usually has an approximate charge of 12 volts or more.
a car battery's voltage typically runs at around 12 volts, but the higher the temperature (either inside your car or outside) the lower it will drop. for this reason, it is advised to have either a/c refridgeration for summer months and heaters for winter months before you go long distances without recharging your battery on hand. alongside that, many people think that simply continuing to disconnect and reconnect their terminals will also reset the voltage on their batteries – but remember never attach any metal flathead screws to any part of your battery as there are sparks involved in doing so!
i hope this answered all your questions about
is a car battery 2 amp or 10 amp?
technically, the correct terminology for the ma level of electric power is amps, not ampers. amps are abbreviations of “amperes”. the difference between amps and ampers is on one side so small that it would be even more incorrect to say “2 amp or 10 amp” than it is to say “2 amp or 2.0132511350132510463234123123 amps.” for reference, there's a calculator on wikipedia you can use if you want an accurate conversion from volts to ohms which will list out multiple resolutions from milli-ohms up through mega-ohms. ohm's law states that voltage equals current multiplied by resistance (in units of ohms).
should i charge my battery at 2 or 10 amps?
it's a common myth that charging your battery at a greater amp will shorten the life of the battery. this is not true. the only thing that determines how long a battery will last is its total number of charge cycles, which has nothing to do with the amps it was charged at. the truth is that you should be more worried about overcharging your phone, so if you have an indicator on your phone let it sit for 10 hours before unplugging it from the charger – other wise it could turn off during sleep and never finish charging!
