A car battery provides 12 volts.
the reason a car battery can provide such high voltage is because it has six cells connected in series and connected in parallel (for safety). this style of connection is the same way that domestic power supply outlets found in homes and offices work. the important difference, however, is that while domestic power supply outlets only marginally exceed 110v, the current drawn from a typical domestic plug socket exceeds 100 amps! and if you add up all these currents (amps) drawn from all sockets at once, you get lots of amperes (a word we use to measure electric current) flowing through your wires which means much more voltage!
how many volts does a car battery need to start?
it's a pretty complicated question with a lot of variables, but most 12v systems will need about two volts or more to start, and about 10 volts or more to make a car engine run.
how many volts should a 12v car battery have?
-12.7 volts should be the minimum to start your engine after it has been off for an extended period of time, but if your battery gets under 12.6 volts you will want to investigate why you are using so much power and what might be draining the charge from the battery. a good way to estimate how many amps are being used is by multiplying voltage by current, by 10 amps per hour = 120 volts x .01 amp x10 hours = 1.2volts or 1211 minutes at 12volks or 20 hrs battery life life at 10 amp hours=12 volts x .002ampx20hours=410 minutes
timing information would also need to be included, as batteries can last
is 10 volts enough to start a car?
the answer to this question is a pretty simple “no,” and it's because cars don't start with electricity. cars use engines that burn gasoline in order to start up. this makes the 10 volts from a battery next to useless when it comes to trying to restart a car, which means you need somewhere around 120 volts of power coming from an outside source in order for your car engine to turn over again.
how many total volts is a car battery?
a car battery can have up to 216 volts. the highest voltage is usually at the starter because it's where the most power is needed.
