yes it does i have done a experiment and energizer last longer that duracell
Energizer battery.
V is the batteries rated voltage. Ah is the amp-hour of the battery. This is a rating of how many amps it can supply for a given period of time. For example a 600 Ah battery with a 100 A load means that the battery should last 6 hours.
The second one should roughly last twice as long as the first one. You can't really say how long as it depends what you are using the computer for, but whatever you are doing the second one will always last about twice as long.
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.
arround 1 hour just joking around 7 hours at medium brightness and low volume.
A 600 mAh battery can produce 75 mA for about 8 hours. If it is called upon to deliver 600 mA, it will last somewhat less than one hour. This is because ampere-hour ratings for batteries are, by standard agreement, normalized to an eight-hour rate. The actual rating is only a comparative rating, so you could properly say that a 900 mAh battery, for instance, will last 1.5 times longer than a 600 mAh battery.

Its more like Duracell. But Ravyonc is better sorta
Duracell
The Kodak Original Nickel Battery is the longest lasting because its made specifically.
AA energizer
For a set rate of power drain and the same battery chemistry, the biggest battery will last the longest. In this case, the 'C' size.
nokia mobile phones
energizer
The newest and longest lasting are the lithium Ion batteries.
I dont know, but I would like to. My hypothosis is that the lithium is going to last the longest because, it is bigger, newer, and has the most voltage.
One battery is probably just as good as another, but a battery that will last longer in cold weather is the AC Delco Super Heavy Duty battery. The more cranking amps a battery has the longer it is going to last when the car doesn't want to start right away.
Sony has the battery extending CD players that last much longer than competitors.
