"Better" doesn't really say enough in this situation.
I'm assuming this is about a laptop that can be fitted with either a 6-cell or a 9-cell battery - in which case the 9-cell will let you run longer on battery, but will usually stick out a bit and make the laptop both bigger and heavier.
So 9-cell is good for runtime, but poor for carrying it around. Your choice.

Can you use a 9 volt charger for a 6 volt battery?
This is not advised! The 9-volt charger might have a current limiter so that nothing burns up, but it any case if left on it will destroy the 6 volt battery by overcharging. A 6-volt charger is not expensive.
Why can a car battery have an open-circuit terminal voltage of twelve volts but be unable to start the car and thus be considered dead?
A fully charged cell in a car battery produces 2.2 volts, there are 6 cells in a battery. That would make true open circuit voltage on a fully charged battery at 13.2 volts. So a 12 volt open circuit reading is a discharged battery. The battery can have enough chemical reaction to produce voltage but not enough potential or power to crank the engine. Think about a fresh 9 volt battery. It is big enough to produce 9 volts, but not enough to crank a car or even light the dome light dimly. A car battery wears out slowly from the time it is purchased. Eventually it doesn't have enough power or amperage left to operate the car.
A resistance of 10 ohms is placed across a 9 volt battery what current flows through the battery?
No current flows through the battery. There is a current through the external circuit. I = E/R = 9/10 = 0.9 amperes.
Explain the construction and working of a dry cell?
a dry cell has many uses. it is basically a battery. a dry cell can be used in torches, clocks, watches, etc. this is the exact definition of a dry cell (from Science Focis 2) "A dry cell is not completely dry, but contains a chemical paste instead of a liquid. As in a wet cell, a chemical reaction generates charge that will flow when the cell is connected to a circuit"
What is 10 plus 9 plus 7 plus 6 plus 6 plus 6 plus 5 equals?
It's a simple example of addition.The solution looks like this:10 + 9 + 7 + 6 + 6 + 6 + 5 = 49
What is the difference between a 6 cell battery and a 9 cell battery?
The 6 cell battery lasts about 2 to 4 hours, the 6 cell is a little smaller and a little cheaper. The 9 cell battery is a little larger, costs a little more, and lasts a little longer.
Is a lead acid car battery the same as a 9 volt alkaline battery?
No, a lead acid battery is a wet cell battery and a 9 volt alkaline battery is a dry cell battery.
How many cells does a 9 volt battery contain?
6 @ 1.5v each The 9 volt battery is a true battery, containing six cells of 1.5 volts each. Most storage devices that we call batteries(i.e. D-cell, AA-cell, AAA-cell) are not batteries, but cells.
How many hours does 56WHr 6 Cell Lithium Ion Primary Battery works with dell laptop mini 10?
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.
How many hours does 56WHr 6-Cell Lithium Ion Primary Battery works with dell mini 10 laptop?
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.
What experiment to determine if a D cell battery or a 9-volt battery has more energy?
you will have to get 2 batteries and compare it
What is 6 AAA batteries?
. There is an AA battery (technically it is a cell, not a battery) that is part of the series D, C, AA, AAA, AAAA. There are holders which hold 6 AA cells in series, creating a nominal voltage of 6 x 1.5 equals 9 volts, but with much more capacity and current capability then a nine volt battery.
When you on the cell phone after putting battery the cell phone shows the time 9 O'clock why?
generic problem for all cell phones
What You Should Know About a Notebook Battery?
The notebook battery is an important feature to consider when buying a new notebook. The type of notebook battery included by the manufacturer determines the laptop's battery life. Most notebooks come with a 6-cell battery, but a few notebooks come with a 9-cell battery. The higher the number of cells, the longer the notebook can function on its battery. Many laptop manufacturers allow you to upgrade to a higher-quality battery for an additional cost when buying a new laptop.
Can you use a 6 volt charger for a 9 volt battery?
No, the battery will be overcharged and battery damage will occur if it is done.
What is the voltage of a dry cell battery?
It depends on the type of dry cell If it is alkaline, 1.5v if it is lithium ion/pol, 3.7v if it is ni-mh of ni-cd, 1.2v if it is ni-zn, 1.6v if it is a AA/AAA/C/D from a supermarket, 1.5v
What are the differences between Cell and Battery?
The primary difference between a battery and a cell is that a battery can be composed of a number of cells. A cell can be a battery. Big flashlights sometimes use "D" cells or "D" batteries as a power source. But a car has a 12 volt battery (that sits at over 13 volts when it's fully charged) and it is composed of 6 individual cells. Generally, a cell delivers a certain voltage that is a function of what chemical reactions are taking place to generate the voltage. To get increased voltage one must add cells in series. The 9-volt batteries like the ones used in smoke detectors have 6 individual cells inside them.
