There's really no telling, as it'd depend on the size of the battery as well as on the chemistry.
This is a measure of battery capacity. It relates to how long a battery can produce a certain amount of current. For example, a fully charged 1500 mAh battery can provide 100mA for 15 hours (or 50 mA for 30 hours or 200 mA for 7.5 hours, etc.) The battery rating is the capacity for a new battery. After many charge/discharge cycles, you will start to see a reduced capacity.Related note: The capacity of a battery doesn't relate to the maximum current you can draw from the battery - that depends on several factors including the type of battery, its size and construction. For example you might be able to safely draw 15 Amps from a hobby style 1500 mAh Lipo (Lithium Polymer), but don't try to get 15 Amps out of 1500 mAh AA Nicads.
Ah means Ampere hours. A 4 Ah battery can release 4 amps for one hour, or 1 amp for 4 hours, or 0.5 amps for 8 hours, or 8 amps for 0.5 hours.
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.
It is the discharge rate of the battery rated in ampere hours. Yours could be any combination from 10 amps for 1 hour up to 1 amp for 10 hours. eg. 5 amps for 2 hours, 2.5 amps for 4 hours.
It is a rating for the capacity of the battery to power a load. A battery rated at 15 amp/hrs has the ability to power a load of 15 amps for 1 hour, or 1 amp for 15 hours, or any combination of the two numbers. Example, 2 amps for 7.5 hours, 3 amps for 5 hours or 5 amps for 3 hours etc.
Volts, amp hours an cold cranking amps.
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.
Ah is amp hours. It describes the capacity of the battery. A bit like the size of a fuel tank. The 12 Ah battery can deliver 12 amps for one hour, 24 amps for 1/2 hour or 6 amps for two hours. Or any other combination of time x amps that makes 12. The 35 amp hour battery is almost three times the capacity of the 12 amp hour battery.
8 hours
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.
It's wrong. Batteries charge at a rate given in Amps. Amps per hour means the charging rate is increasing. Battery capacity is often stated in units of ampere-hours, which means that so many amps are needed in 1 hour, or half so many amps in two hours etc.
To convert milliampere-hours (mAh) to amperes (A), divide by 1000. Therefore, a 1500 mAh battery has a capacity of 1.5 amperes.
