    "Cells" are the basic power storage components inside laptop batteries.

    A 12 cell battery will provide power twice as long as a 6 cell battery.

    e.g. If a 6 cell could power your laptop for 3.5 hours then a 12 cell would power your laptop for 7 hours.

    It's how the battery is physically assembled.

    The battery will have some number of lithium cells connected in series to match the voltage of the laptop, eg. 3 cells for a nominally 11.1V battery.

    They can either be big, high capacity cells or it can have say, two or three sets of cells connected in parallel. That keeps the same voltage but higher capacity again, the same as with big cells but more small cells are easier to fit in the battery casing.

    The only thing that matters with different versions (assuming they are all rated as compatible with your computer) is the Amp-Hour (Ah) capacity of the battery.

    A larger AH rating gives longer run time on the battery; eg. a 3.6Ah would give 50% longer runtime than a 2.4Ah. Some are rate in milliamp hours; mAh, so 3600mAh = 3.6Ah.

    simple answer:

    more cell battery has more longer it will last

    from my experiance on a HP laptop 6 cell lasts about 3.5 hours on single recharge and 9 cell lasts about 5 hours depends upon usage.

    i am currently using my laptop for web surfing and for watching YouTube

    Performance will be identical, but more cells translates to more battery life. The more cells you have, the longer you can stay away from the plug.

    all the info u need to buy a new battery for ur laptop is the model number.

    As far as i know, a 6 cell battery has 6 1 volt cells. So its a 6 volt battery. 8 cell would be 8 volt. 12 cell would be 12 volt. More cells hold more power. So a bigger battery lasts longer. But you should check the specs for your laptop to see what the biggest it can take is.

    The question from the reader is a great question for it gets to the heart of battery manufacturing and begins to unravel the power of a battery. The answer is simply: 12 cells. But what does the answer mean and how does the number of cells relate to the overall value of a battery? Let’s find out…

    What is a Battery and How Does it Create Energy?

    A battery is a device that converts chemical energy into electrical energy. Batteries have two electrodes, an anode (the negative end) and a cathode (the positive end). Collectively the anode and the cathode are called the electrodes. What is positve and what is the negative terminal? It would be great to simply say that the anode is negative and the cathode is positive, however, that is not always the case. Somtimes the opposite is true depending on battery technology.

    In between the battery’s two electrodes runs an electrical current caused primarily from a voltage differential between the anode and cathode. The voltage runs through a chemical called an electrolyte (which can be either liquid or solid). This battery consisting of two electrodes is called a voltaic cell.

    Therefore batteries in effect create electrochemical energy. In order to convert chemical energy into electrical energy there is a chain of events that have to occur prior to the creation of electrical energy. Key to the creation of electrochemical energy in batteries is that electrical energy is injected into two chemicals in a solution. Electricity is introduced into a battery via a charger. The charger acts as a conduit of the pushing electrons that are forcing their way into the chemical lithium. This charge process involves intercalation: the joining of a molecule (or molecule group) between two other molecules (or groups). Intercalation is the process of ions being pushed by electrical current into solid lithium compounds. Lithium is one of the chemical components used to create electrical energy in batteries. Lithium compounds have minuscule spaces between the crystallized planes for small ions to insert themselves from a force of current. Ionizing lithium loads the crystal planes to the point where they are forced into a current flow. Intercalation replenishes, in effect, lithium but the net result of ionization is the ultimate depletion of the lithium reactive property. You could say if you use it you will lose it!

    What Type of Lithium Cell is Used in Laptops

    Now this brings us to battery cells and our original question from the reader. Lithium based battery cells are good but there are a variety of lithium based battery cells. For example the lithium based cell identified as 18650 is one of the most common battery cell on the market for laptops. 18650 is manufactured by many manufacturers including many private branded companies to public companies like LG, Sony, Sanyo, Samsung, Panasonic.

    18650 is a 3.6V cylindrical Li-Ion cell. 18650 has no memory effect (distinguish between digital memory effect) and longer storage life than NiMH battery cells. 18650 is light weight and has a high energy density. It is in effect perfect for building batteries for laptop and other portable power devices.

    The additional technical specifications for the 18650 battery cell include:

    Nominal Voltage Average 3.7 V – the concept of nominal voltage is that voltage range exists depending on the number of cells in the battery.

    Nominal Capacity - 2200 mAh (above 2200 the stability of lithium based cells is called into question)

    • Max. Charging Current - 2.4 Amps Max.

    • Max. Discharging Current - 4.6 Amps max.

    • Dimensions (DxH) 18.3 mm (Max 18.4) x 64.9 mm (Max 65.1)

    • Weight 46.5 g (1.64 oz)

    Internal Impedance Internal Impedance: less or equal to 90 ohms

    Cycle Performance is 80% of initial capacity at 300 cycles

    Now as stated above the reader asked how many cells were in the Toshiba Satellite M105-S3041 Laptop Battery? The battery is rated at 10.8 volts and a capacity of 8800 mAh.
