i just got a battery and it says 12 volts 5 amps how many amps per hour can it put out is it 5 ?

something like that.

Batteries are rated in Amp-Hours, not Amps per hour.
Batteries are made differently, so the only real way to tell your battery's ACTUAL capacity is to either trust the rating printed on it, or measure it over time, with an ammeter.
I have a 12V Deep Cycle that is rated at 96 AH, which means that when it was brand new, and had a fresh charge, it could provide 1 AMP for 96 hours, or 2 AMPS for 48 hours, or 3 AMPS for 32 hours....etc.
Amps are simply a measure of current draw. Your battery will give you as many amps as you draw from it, as long as it can physically handle (without exploding or melting) the discharge until it is drained.
Hope this helped, and Good Luck.

amp is a rate.
1 amp means one Coulomb of electrons will flow past a point each second.
Asking how many amps per hour you are getting from a battery is like asking how many miles per hour can a car go each hour. it makes no sense.
I think maybe you are thinking of amp-hours which is the energy a batter can supply. To find this you take the current times how long it can supply it. This is completely independent of voltage or amperage.
Say you had a 20amp our battery. If it is supplying 5 amps it will last for 4 hours, but if you are only drawing 1 amp it will last for 20 hours.
So really what it comes down to is your question makes no sense and even if you meant how many amp-hours is the battery there would be no way to tell that from the information you gave.
Your 5 amp rating means your batter can supply 5 amps without overheating or having a serous voltage drop. You can get more out but the more you draw the lower the voltage will drop.

The concept of amps per hour is meaningless. But ampere-hours is meaningful, particularly for a battery. Storage batteries often show ampere-hour ratings. If the battery claims to be good for 5 ampere-hours (not unreasonable for a small lead-acid battery), it can deliver 5 amperes for one hour.

Your battery can supply 12V,5A load supply for 5 hours.

Depends on what you're using it for ... low power or high power consumption !!
