Recently, I change my stock battery to a maintenance free battery. I heard that my ride (Lancer 2006)s battery needs 55-60 Amp but I install a MF battery of 70 Amp. It was a direct fit in and replacement of my old stock battery. Are batteries are higher Amp bigger in size? Any side effect to the.

Car battery amps per hour.

If a battery is rated as 100Ah, it will produce 100 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 50 Amps, 4 hours at 25 Amps, and so on. Find out how to test and charge a car’s battery here.
A rule of thumb is that for a 1 hour discharge rate (i.e. drawing 10 amps from a 10 amp hour battery, or 1C) you will only get half of the rated capacity (or 5 amp-hours from a 10 amp-hour battery). Charts that detail this effect for different discharge rate can be used for greater accuracy.
This battery is putting out 400 amps. No wonder batteries make good stick and wirefeed welders. This is the important test for a car’s starting battery. It’s made to deliver high currents but not for very long. This is a good test to use while scavenging for batteries. If a battery doesn’t pass, it might just need charging.

On the top of the battery, there are some important numbers to know. Cold Cranking Amps (CCA): This number is important if living in a cold climate. It indicates the amount of amperage the battery is capable of delivering zero degrees Fahrenheit for 30 seconds.
BatteryStuff Tech 17 watts / 12.5 volts = 1.36 amps. 9 of these lights will pull 12.24 amps per hour. running 8 hours is a total of 97.92 amps. The calculator recommend a battery with ~ 200 AH, which is still over 100 lbs of weight. Inverters can add on average 15% inefficiency to the power draw.
The C rating tells you how many amp hours the battery can provide for a very specific period of time. For instance, at C/5 a battery might safely provide 26.8 amp hours. This means that is supplies 26.8 amps in the duration of 5 hours without dropping off. Meanwhile, the same battery may safely provide 36 amp hours for a period of 100 hours.

Generally, a car battery pulls approximately 400 amps for small vehicles to start and more than 1000 amps for the large ones. That is why the car manufacturers provide bigger amps in the car battery than it needs to start. The amps in the car battery should always remain close to 00.00 to prevent it from damaging.
A heated rear window will use up 48 amps in about 12 hours. Battery charges provide different amps. The typical charger charges your battery at about 2 amps. That means that the charger will increase your battery power by about 2 amps for each hour that it is connected. At the speed of 2 amps per hour, it will take the charger about 24 hours to.
The amperage capacity of a car battery is measured in two different ways: amp hours or cold cranking amperage, or CCA rating. The measurements mean two different things. Most automobile batteries have a capacity of between 45 and 50 amp hours. For most passenger cars, the battery CCA will fall between 400 and 600.

This arrangement lets flakes off of the lead sulfate plates collect on the bottom for a longer time due to charge / discharge cycling before the lead scrap heap shorts the cell plates and stops battery action. A 120ah ( amp-hour ) battery can deliver 1 amp for 120 hrs OR 2 amps for 60 hrs OR 3 amps for 40 hrs OR 4 amps for 30 hrs OR 6 amps for.
If a battery’s ampere-hour is 100Ah, this tells you the battery can deliver 5 amps of power for 20 hours. If you used 10 amps per hour, it would last for 10 hours, and so on. Discharge period used for Ah rating.
The best car battery charger is one that provides a fairly fast number of amps per hour for the initial portion of the charging, and then switches over to a slower number of amps per hour for the finishing of the charging, and then lowers the amps provided even more so that it can maintain the charge of the battery without causing damage to the.

A AA battery has a 2,200 mAH. A larger example, such as a lantern battery, has a capacity of 11,000 mAH or 11 AH. Car batteries have capacities of a few hundred AH. In addition to the larger overall capacity, a car battery has lower internal resistance than small consumer batteries, so it delivers large amounts of current on demand.
C-rate of the battery. C-rate is used to describe how fast a battery charges and discharges. For example, a 1C battery needs one hour at 100 A to load 100 Ah. A 2C battery would need just half an hour to load 100 Ah, while a 0.5C battery requires two hours. Discharge current. This is the current I used
A battery with a capacity of 1 amp-hour should be able to continuously supply current of 1 amp to a load for exactly 1 hour, or 2 amps for 1/2 hour, or 1/3 amp for 3 hours, etc., before becoming completely discharged. In an ideal battery, this relationship between continuous current and discharge time is stable and absolute, but real batteries.

An amp-hour — properly “ampere-hour” — is a unit of measure describing electrical charge capacity. If a battery is said to have “20 amp-hours of capacity,” it means that it can hypothetically discharge one amp of current for 20 hours, 20 amps for one hour, or any combination of amps and hours that equal 20 amp-hours.
This means that a battery has a 100 A.H. capacity if it is discharged over 20 hours, or at about 5 Amps-per-hour (100 A.H. / 20 hours = 5 Amps DC). However, this same battery would last only one hour if the discharge rate was 50 Amps-per-hour (50 Amps DC x 1 hour = 50 A.H.) because of the high rate of discharge.
Automotive car batteries vary in capacity but a large automobile propelled by an internal combustion engine would have about a 50 ampere hour battery capacity. Since one ampere hour can produce 0.336 grams of aluminium from molten aluminium chloride, producing a ton of aluminium requires transfer of at least 2.98 million ampere hours.
