A 5Ah battery is rated to be able to sustain a 5A load for one hour. From there you can figure out how long it will last with your load. The number in the Ah rating is always what it's rated to last to one hour.
one hourAh, Ampere Hour or Amp Hour all describe the same characteristic of a battery – how long it will last when connected to the item it is powering. This is often referred to as the 'capacity' of a battery. The measurement is often misunderstood as, for example, “a 5Ah battery will power a 5 amp device for one hour”.
A simple definition of amp hours would be the amount of amperage that the battery pack can deliver for one hour. A 5.0 amp hour battery will give you 5 amps for an hour. Unlike voltage, this is not a fixed figure. You can draw a higher amperage from a battery and get less run time.
Yes, it can be used and how the exchange would look like. If you are using a 4Ah battery and heading towards the 5Ah would mean that your application could run up to 25% longer. In contrast, if you want to change from 5Ah to 4Ah, this means your electric device will run up to 20-23%.
12AH means it can deliver 12 Amps for 1 hour, or some ratio in between such that current times time (in hours) = 12 before it goes dead. So the 12AH battery can deliver 500W for 1.152 Hours.

Similarly, a 5 amp-hour battery will give you 5 hours of runtime at a 1 amp load. With a 5 amp draw, that 5Ah battery will give you an hour of runtime. A 1Ah battery will give you 12 minutes of runtime under that same 5Ah load (under simplified conditions). Higher power tools will go through battery charge quicker.
approximately 120 hoursThe watts/volts are equal to the amps per hour. A tiny device such as led lighting of power 1.2 watts running on a 12volt power source will use 1.2W/12V = 0.1 amps. Therefore, a 12ah (amp-hour) battery will last for approximately 120 hours.

According to the author, NiCD batteries fail completely because they're shorted out by "crystal dendrite growth," an accretion that can apparently be blasted away with a quick jolt from a welder attached to a high-voltage source.

How often should it be replaced? There are no maintenance requirements for a valve cover gasket. It only needs to be replaced if it leaks. If the valve cover gasket is old, it's also often replaced when doing a major engine repair.
Melted wax does not evaporate, only the scent dissipates, so make sure to remove the used wax from your warmer before adding a new cube If using Happy Wax melts, 2-3 wax melts generally yield about 8 hours of fragrance. You are welcome to reuse the wax as many times as you want until the fragrance dissipates.
20 minutes to half an hour most to take each wheel off in turn Balance and weight each wheel ion the machine then replace each wheel in turn on your. Vehicle. That is for an average car. Once the car is IN the shop, it typically takes about fifteen to twenty minutes.
