no
A non-rechargeable wet cell battery.
No, an automobile battery is a wet cell battery not a dry cell battery.
one has more power
No, a lead acid battery is a wet cell battery and a 9 volt alkaline battery is a dry cell battery.
No, you can not charge a mobile battery using torch cell. <<>>> i think charger need and mobile the same. also battery.
A primary cell can't be recharged, for example am ordinary 'D' cell, while secondary cells are rechargeable, e.g. one of the cells in a car battery.
If we assume the same battery chemistry and quality, and the same drain, then the D cell will last longer than the AAA cell, as the bigger size means it'll hold a bigger amount of energy.
First off, a battery is what you get when you stick several cells together, so for the most common 1.5 volts the strictly correct answer is that they are cells, not batteries. The 9 volt rectangular thingies though, they are batteries. Primary vs secondary is about rechargeable or not. A primary is not rechargeable, so a Duracell would most likely be a Primary cell.
If we assume the same battery chemistry and quality, and the same drain, then the AA cell will last longer than the AAA cell, as the bigger size means it'll hold a bigger amount of energy.
It really depends on what kind of battery, what kind of laptop, what kind of processor and what you do with your laptop. Typical reliable answer for most new 6 cell battery is 3 hours at least, and 9 cell battery last 4-5 hours.
The battery life (assuming it is a primary cell) is determined by the Ampere-hour drawn from it. You cannot connect a 3.5V bulb directly to a 9V battery. The bulb will fuse.
