Batteries are not measured in Amps, but rather as Amps they can emit in an hour. The standard home unit for battery power is AH our Ampere Hour.
At 12 volts the amps in your battery are then described in Ampere Hours or Amps per hour.
From that we get that if the battery was plugged into a 12v device that drew 225 amps, your battery would run out in 1 hour.
Similarly if it was connected to a device requiring 112.5 amps it would take 2 hours to run down.
Wikipedia has stated that this is an approximation, that at really high currents (measured in how many Amps you are currently using) the battery life is shorter than expected and that the Ampere hour is generally supposed to consider a 20 hour cycle of discharge
(therefore meaning lower amps per hour)
This brings the battery back to it's "normal" drainage pattern.
@ 12v and 11.25A your battery would take 20 hours to drain.
What else can I help you with?
How many volt amps in 12 volt battery?
Depends on the battery. It is listed on the battery as Cold Cranking Amps (CCA).
How many amps and volts in a car battery?
modern cars use a 12 volt battery. Amps depends on the battery. Common sizes range from 500-800 cold cranking amps.
How many amps are in 40 volt amps?
Multiply the vots by the amps to find the volt-amps. Or divide the volt-amps by the voltage to find the amps.
How long to charge a 12 volt battery at 2 amps?
It takes between 8 and 12 hours to charge a 12 volt battery at 2 amps. The actual time will depending on how much charge is in the battery initially.
How many watts does my 12 volt 2 amp battery charger draw?
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
How much volt ampher usedneed to charge 6 volt battery?
That would depend on the size of the battery, you want the amps of the charger to be reasonably proportional to the capacity of the battery.
What is the amperes of the 300 volt battery for the GMC Hybrids?
240 amps AC
How many amps are in a 9volt battery?
It varies from one 9 volt battery model to another. The typical Alkaline 9 volt battery you find in many toys and smoke detectors has 565 mAh (Milliampere Hours) of power. A Zinc Carbon model has 400 mAh. A Lithium has 1200 mAh. There are 1,000 mili amps in 1 amp.
How long does it take to charge a 12 volt battery at 1.5 amps?
8 hours
How do the current produced by 1.5 volt flashlight cell and a 12 Volt car battery compare?
They don't. Car batteries produce 100's of amps of current. a 1.5Volt flash light battery produces milli-amps at best.
Do you charge a battery for a tractor on 6V 2amps or 12V 6 amps?
6volts 2amps for 6 volt battery, and 12 volts 6amps for a 12 volt battery. Don't charge a 6 volt battery on the 12 volt setting or it will explode!!!!!!!!! you're ok going the other way though.
What charger do you need for a 24 volt battery?
The formula you are looking for is I = W/E. Amps = Watts/Volts. 300/24 = 12.5 amps. A good charger with an output of 15 amps will do the job nicely. The time that it will take to charge the battery will depend on the amp/hrs of the connected battery and the state of discharge that the battery is in when charging starts.
