You measure it with a clamp-on ammeter.
mAh = milliamp hours, which is battery capacity
That would depend on the actual battery's specifications. I've seen some D cells rated as low as ~2000 mAh. However a full true D cell should have a rating between 10,000 mAh and 15,000 mAh.
These figures represent capacities of use for batteries. If a device uses 50 mA an hour on a 800 mAH battery, the device would operate for 16 hours before depleting the battery. If the same device was connected to a 700 mAH battery, the device would operate for 14 hours before depleting the battery.
probably, yes. imagine putting twice a much AA's in your radio or whatever.
4400 mAh means that the battery can produce 4400 mA for one hour. Similarly, 7200 mAh means 7200 mA for one hour. In reality, these specifications are for a eight-hour rating, meaning that the 4400 mAh battery can produce 550 mA for eight hours but, comparatively, you can just ratio the ratings, so the 7200 mAh battery will last 60% longer than the 4400 mAh battery There's more to it than that, however, as you need to know that the laptop is designed to use either battery, otherwise the camparison is meaningless.
A: It certainly can provided the voltage output must are equal
A typical D battery has a power output of around 1.5 volts. The power output can vary slightly depending on the specific brand and type of battery.

the answer is c : 1400 mAH
Milliampere-hour is commonly written as mAh. It is a unit that is used to measure electric power.
it depends how the batteries are connected.if you put the batteries both in positive side up you probably have a 1.5 volt system.if you put one battery positive side up and one down you probably have a 3 volt system.Check to make sure before you connect anything because you can damage the the water pump by connecting it to the wrong voltage or by reversing polarity.if its a 1.5 volt system you have about 2000 milliamp/hours at you disposalin a 3 volt system you have about 1000 milliamp/hours at you disposalfind the the time in hours the water pump will run on a new set of batteries will last.1.5v 2000 mAh/1hour= 2000mAh 1.5volt power adaptor1.5v 2000 mAh/2hour= 1000mAh 1.5volt power adaptor1.5v 2000 mAh/3hour= 667mAh 1.5volt power adaptor1.5v 2000 mAh/4hour= 500mAh 1.5volt power adaptor1.5v 2000 mAh/5hour= 400mAh 1.5volt power adaptor1.5v 2000 mAh/6 hour= 334mAh 1.5volt power adaptor3v 1000 mAh/1hour= 1000mAh 3volt power adaptor3v 1000 mAh/2hour= 500mAh 3volt power adaptor3v 1000 mAh/3hour= 334 mAh 3volt power adaptor3v 1000 mAh/4hour= 250 mAh 3volt power adaptor3v 1000 mAh/5hour= 200mAh 3volt power adaptorRemember as Tim the Toolman would say more mAh is better.
Zinc-carbon AA =400-900 mah Alkaline AA = 1700-3000 mah :: I believe the above answer to be misleading/misguiding, the question is "How much mA does a single AA battery have?" not how many mAh. in mA a single AA batter will have about 3.6mA to 4.0mA it is important to distinguish mA from mAh, if one were to connect a device that required 4.0mA to a power source of 400-900mA this would likely destroy the device. mAh deals more with how long the battery life lasts.
Yes, Micromax canvas 2.2 is compatible with 10400 Mah power bank.
I just saw Rock Space power bank advertisement on rockspace.in they have 10000 mah,13000 mah and 20000 mah power banks ! in my opinion, its a value for money if we compare with others
About 2 hours.
The GMEGC 2600 mAh AA batteries are primarily used to power various electronic devices that require AA batteries, such as remote controls, digital cameras, flashlights, toys, and portable gaming devices. With a capacity of 2600 mAh, they provide a reliable and long-lasting power source, making them suitable for high-drain applications. These rechargeable batteries offer an eco-friendly alternative to disposable options, allowing users to recharge and reuse them multiple times.
That depends on the amount of power being drained from it.
