The power and longevity of a battery is noted by its Amp Hour (Ah) rating. Basically, this denotes how long a battery will put out an amp of power if it isn't recharged.
A car battery is one of the basic issues behind most of these dilemmas. This is because the car battery pulls out greater amps and it ruins the battery life in no time. Leaving any interior car appliance ON is the vital reason for battery draw. A multimeter might be a great idea to diagnose how many amps a car battery draws. In theory, with a perfect conductor you are looking at over 2000 Amps. With their test, they saw 1700 Amps. And these are just 33 Amp Hour batteries, small compared to most cars. These are UPS batteries!
- A car battery could pack a pile of intricate specifications from Voltage, Reserve Capacity (RC), Pulse Hot Cranking Amps (PHCA), or Marine Cranking Amps (MCA). Yet in order to check how many amps on a car battery, we should round up to three indicators only: CA (Cranking Ampere), CCA (Cold Cranking Ampere), and the car battery's capacity.
- Look for the label on the side or top of your battery to find out the Ah your battery delivers, when it's fully charged and in good condition. For example, a deep cycle battery may have 12V 50Ah on the label, meaning it produces 12 volts and 50 amp hours. Step 2 Turn on the multimeter.

For example if a battery is rated as, say 50Ah, it will be able to provide 50 amps for 1 hour. This does not necessarily mean a battery will last only one hour, because it will last 2 hours if it's asked to produce only 25 Amps, 5 hours at 10 Amps, and so on.
But the most power intensive part of the car, the starter, may draw 400 amps in the instant you turn the key! Sequence diagram with multiple actors &. Which is why you can run the battery down in 5-10 minutes of cranking if it doesn't start immediately.
Batteries are also rated according to their Cold Cranking Amps (CCA), which denotes the peak power they have to turn over the engine and get it started in cold weather.

This is why it's worth taking note of these two figures, because there's little point in having a powerful battery with lots of cold cranking amps just to deliver the 250 amps a little four cylinder motor needs to turn over. On the other hand though, a 3/4 ton diesel truck needs massive amounts of power to crank, thanks to the high compression and huge pistons, so often have a pair of batteries just to get going.

What drains a battery
Car Battery Amps Or Volts
Various situations and conditions can cause you vehicle's battery to become low or discharged. At lower temperatures, the chemical reactions in a battery slow down and produce less power for a given time, which can make a marginal battery unable to start the car. Also in winter the engine is harder to turn over in the first place because the oil is thicker, and the metal actually shrinks microscopically making everything tighter. Plus the fact that systems such as the ventilation, rear window defroster, and (if your car has them) heated seats, are all in more frequent use, and people make shorter trips starting the car more frequently
It pays to garage your vehicle, if you can, to keep it warm, and in extreme conditions use an automatic charger to kep the battery at max power. A low amperage charge will also keep the battery warm and stop it from freezing so readily in sub zero conditions.
Also, make sure you turn off the heated seats and windows once they've done their jobs, because if they're all switched on when you turn on the ignition they can quickly deplete your battery to the point that it hasn't enough power to start the engine.
it's a good idea to take your vehicle for a slightly longer journey (at least 30 minutes or so) once a week just to give the battery a much-needed chance to recharge.
