how many amps for a 12 volt battery?
107307
How many amps does a 12-volt car battery have? A typical car battery with 12 volts rating has a capacity of 48 Ah. It means that when fully charged, the battery can deliver one amp for 48 hours, two amps for 24 hours and so on.

A 12-volt battery could take up to 12-24 hours to charge fully. When recharging your battery, remember that if it gets too hot while you're charging it, you need to stop charging.

A 12-volt, 1 amp-hour (abbreviated Ah) battery and a 6-volt, 2Ah battery each store 12Wh, but the voltage is usually a critical parameter for a battery, and once a voltage is selected, the capacity can be specified by the amp-hour rating.

To charge a 12 volt and 200 age battery unit about 2400 watts to make it charge fully. In average day quick at about 5 hours of sunlight if you have 100 Watts solar panel then in a whole day from a single panel will get 500 watts.

Amp-Hours and Watts Defined So, if a battery provides 10 amps of current for 10 hours, it is a 10 amps × 10 hours = 100 Ah battery. A watt (W) is a measure of power, with 1 watt representing one joule (a unit of energy) per second. So, if a light bulb uses 60 watts, it requires 60 joules of energy per second.

Examine the battery casing for written clues. Most batteries have the voltage and maximum current stamped into the plastic case or printed on a label. ... For example, a battery showing "12V" and "50A" is a 12-volt battery with a maximum current capacity of 50 Amps.

You need to connect an amp meter in series with the coil and 6 volt battery. A 6 volt coil will draw 4 amps. If you have an accurate ohm meter, reading across the posts of a 12 volt coil should be about 3 ohms. A 6 volt coil is about half of that.

A 12V lead-acid battery will not be damaged by overcharge if the voltage is kept low enough to avoid electrolysis, and the charging current is kept below 0.2C (5 times less than the Ah capacity). ... If it can put out more current than the battery can take then the battery may overheat.

For a 12V system, if you need to replace 100A/h of charge to your batteries each day, and you have 8 sunlight hours in each day you will need... 1200WH / 8H = 150W of solar panels. In reality it is recommended that you always overrate your requirements by at least 20%, therefore you would need 180W of solar panels.

For a 12 volt, leadacid battery, the voltage measured between these two points should be between 11 and 13 volts. The closer the voltage is to 13 volts, the closer the battery is to being fully charged. The closer the voltage is to 11 volts, the closer the battery is to being “dead”.

When the battery is not being charged and not delivering charge to a load, this is the rule of thumb. For a 12 volt, leadacid battery, the voltage measured between these two points should be between 11 and 13 volts. The closer the voltage is to 13 volts, the closer the battery is to being fully charged.

Typically, the larger the battery, the higher the amp rating. The internal chemistry of the battery will also affect the amp rating. Most car batteries have a capacity between 550 and 1000 amperes.

So therefore if the draw on the battery is very high eg 12v x 100,000 amps ( I would like to see the construction of this battery) = 1,200,000 watts. Eg when you start your engine your starter motor will draw a lot of electricity ( a starter motor is vertically a dead short.)

The typical furnace will draw about 8 amps of power. It is a good idea to have solar or generator power to supplement the charging of your batteries when not connected to shore power. The 12 volt battery system in your RV runs many of your electronics on your Camper, RV, or Travel Trailer.

Starting the engine will require 250 amps for a half second, and the most current a 1.5-volt AA battery can produce is 10 amps. Given the above, you'd need to start with a string of eight AAs to get your necessary 12 volts.

Depending on the voltage of your electrical system, you may need to connect batteries together to create a bank at 12, 24 or 48V. Using a higher voltage is also a useful way of reducing voltage loss over longer distances or reducing the size of charge controller you need.

The 16 amps maximum for 18 gauge wire is a conservative estimate for several feet of wire. In your case with only 12" the 18 gauge wire will easily handle more than 16 amps.
