Current is measured in Amps. Rechargable AAA batteries put out 850 mAh, or 0.85 Amp-Hours, meaning that it will run 1.2v (Rechargable AAA Voltage) at .85 amps for 1 hour. But to really get a feel for how much power it holds, you need to use watt hours, which are amps times volts. 1.2v X .85 = 1.02 watt hours, or just enough to run a lightbulb for 90 seconds.

∙ 9y agoAn AA battery has 4.0 mA.
Battery capacity is measured in mAh (milliamp hours), that's how much electricity can be delivered for how long (depending on consumption). The best AA NIMH (nickel-metal hydride) rechargeable batteries rate at around 2100 mAh - at 1.2volts. And regular (off the shelf) alkalines anywhere from 1500 - 3000 mAh at 1.5 to 1.7 volts. There are some industrial/military batteries that have a 'little bit' better performance and are sealed better - so that they wont leak as easily when dead and can take rough treatment.
While the battery's capacity (the mAh figure discussed above) affects the maximum current which can be drawn from a battery, other factors play an important role in limiting the current. A perfect battery could delivery an almost infinite amount of current if the duration of that demand is sufficiently short.
In a thought experiment, it is perfectly possible to burn through a fairly thick wire by shortening one of these batteries. (Do not try this at home. The battery might explode of catch fire, and the wire can spark, will get very hot, and metal might evaporate which could severely harm you.)
However, no battery is perfect. The chemical and physical assembly inside the battery dictates how quickly the stored energy can be made available as an electric current, and other aspects define an "internal resistor" which limits the maximum current. Therefore, two or more batteries of the same nominal capacity but different design will deliver a different peak current.

I have rechargeable with 2800ma capacity so they are close to alkaline.

What is the width of a AAA battery?
AAA batteries measure one centimeter wide.
How many volts in a c?
A "C" battery has a 1.5 Volts same with AAA, AA, and D batteries.
Can i use a home charger that has 3to 12V300mA output to charge my car battery at home?
No. The charger for a car battery has an output measured in amps. You have an output measured in milliamps. There are 1000 milliamps to 1 amp. Way too small.
How long will it take 532 milliamps to drain a 12 volt battery?
Cannot say as different batteries with the same voltage have different capacity (rated in Ampere Hours). If you had instead asked "How long will it take 532 milliamps to drain a 350 Ampere Hour battery?" that would be much easier (657.89 hours).
Does AA batteries last longer than AAA batteries?
The main difference between a AAA and a D battery is the size. With the size, you can put more charge holding materials, such as Lithium-Ion, Ni-Cad, etc. They both have the same voltage output, but the D battery can hold more charge. Since electronic devices "pull" charge from the batteries, the D battery will last longer comparitively to a AAA battery in a similar device. This is why you see AAA batteries used in small devices, that have low current draw, and D batteries are used in items that require more power, such as boom boxes, and such.
How many volt does a AAA battery have?
alkaline AAA = 1.5 volts
What battery brands make AAA batteries?
Many different battery brands include AAA batteries some examples of AAA battery brands include two of the biggest battery brands, Energizer and Duracell.
How long is the shelf life of a triple a battery?
AAA is the size of the battery, there are many types and makes of AAA battery and the shelf life for each is different.
How many volt does an AAA battery have?
1.5 volts
How many bb's can you shoot per charge on a 9.6 volt 1100 mah airsoft battery?
Here is a quick tip, mAH stands for Milliamps. however many milliamps a battery is rated, that's about how many shots you should be able to get off on a full charge.
What does mah do?
mAH stands for milliamp-hours. It is a measure of the power capacity of a battery. If a battery has a mAH rating of, say, 480mAH, it means the battery can supply 480 milliamps for one hour, or 960 milliamps for a half-hour, or 240 milliamps for two hours, etc.

What is smaller then a AAA battery?
a AAA battery. Or a watch battery, or a AAAA battery, or any number of battery types. http://en.wikipedia.org/wiki/List_of_battery_types
What are the benefits of a AAA membership?
There are many benefits to having an AAA membership. For example if a car breaks down, AAA offers battery replacement, battery boost and fuel delivery. Check out their official site for more benefits.
What is the relationship between the cost of a AAA battery and the life of a AAA battery?
They both involve batteries.
What is in a AAA battery?
chemicals
