A rechargeable battery can be used for 110 hours supplying a current of 188 milliamps (mA). What is the capacity of the battery in amp-hours (Ah)?

Ampere-hours means amperes multiplied by hours. Similary, mAh means milliamperes, multiplied by hours.
Simply multiply the hours by the milliamperes. That will give you mAh. Then divide by 1000, to convert to Ah.

Can a 4400 mAh battery replace a 4700 mAh one?
Milliamps Hour (mAh) is important because it's the easiest way to distinguish the strength or capacity of a battery. The higher the mAh, the longer the battery will last. Batteries with different mAh ratings are interchangeable. If your battery is rechargeable then the mAh rating is how long the battery will last per charge. Milliamps Hour is 1/1000th of a Amp Hour, so a 1000mAh = 1.0Ah Think of a cars gas tank. Voltage is how much gas is being used, and mAh is the size of the gas tank. The bigger the gas tank (mAh) rating the longer the device will run. If your battery is rechargeable, then think of the gas tank as refillable (rechargeable).

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 does 300mah mean?
the 300maAH is volt rechargeable battery is the highest true capacity battery
How many volt can 1000mah diliver?
1000 mAh is the capacity of the battery. A single rechargeable cell would give 1.5 volts, regardless of its capacity.
How long will duracell rechargeable batteries last?
No set answer to that, it depends on the size/capacity of the battery and what it's powering.
How many hours does 1540 milliamps of power equal?
None. The time depends upon the capacity of the delivery system, eg a battery with a rating of 1200mah (1200 milliamp hours) means it holds enough charge to deliver 1 milliamp for 1200 hours; or it can deliver 2 milliamps for 600 hours, or 1200 milliamps (=1.2 amps) for 1 hour, or 3600 milliamps (= 3.6 amps) for 1/3 hour (= 20 mins), etc.
How long should an AA rechargeable battery last?
No set answer to that. It depends on the capacity of the battery and the power consumption of what it's connected to.
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).

Best Rechargeable Batteries for an Xbox 360 Controller?
Rechargeable batteries are almost crucial for Xbox 360 players, as the AA batteries seem to die fast. While there are many on the market to chose from, one of the best is the Sanyo Eneloop rechargeable battery. Breakthrough technology has allowed these NiMH rechargeable batteries the ability to increase electrical capacity, reduce self-discharge, and maintain longer charge cycles. Most Xbox 360 players notice that they are able to play games longer on a single charge, compared to other rechargeable batteries.
