How many cells in the battery?

Question from reader: "How many cells in the Toshiba Satellite M105-S3041 laptop battery? Toshiba Satellite M105-S3041 technical evaluation and 10.8 V 8800 mAh lithium-ion battery.

Question from a reader who is a big question to come to the heart and the manufacture of batteries, the battery begins to unravel. The answer is simple: 12 cells. But what does it mean and how they react to the number of cells onThe total value of the battery? Let's find out ...

As the battery will operate to create energy?

The battery is a device, the chemical energy into electrical energy. Electrochemical energy storage battery to a chain of events that has, before the creation of electricity. Electricity is introduced into the battery via a charger. Charger serves as a channel for the electrons pushing their way into the chemical lithium. This fee covers the process ofIntercalation, where the electrons crystallize in combination with other molecules in the small gap between the lithium lithium levels. Electrons are flowing mainly ionization of lithium, the burden of network layers, where they are forced to. Topping intercalation, in fact, lithium, but the result is ionization of the possible exhaustion of the reactive properties of lithium.

But what is good for the lithium batteries, lithium is very reactive metals.Lithium has a very high electrochemical potential. In some cells, the electrochemical potential of lithium five times higher than the corresponding size of lead-acid cell and three times higher than alkaline batteries. Lithium Lithium is smooth, flexible fit in tight formations (perfect for small projects in PDA cells. Laptop, camera, etc. ..).

What type of lithium cells in laptops

Now we come to the battery cells and our originalQuestion from a reader. Li-ion battery cells are good, but there are other cell lithium battery. If the lithium cell is identified as one of the 18,650 most common cell battery on the notebook market. 18,650 manufacturers produced many, many private companies, public branded companies such as LG, Sony, Sanyo, Samsung and Panasonic.

18,650 is a 3.6V cylindrical Li-ion battery. 18,650 No-memory effect (the difference between digitalMemory effect) and a longer shelf life than NiMH battery. 18,650 is lightweight and has a high energy density. It is just perfect for building batteries for laptops and other portable electronic devices.

Additional technical requirements for 18,650 battery packs:
Average nominal voltage of 3.7 V - the concept of voltage is the voltage, depending on the number of battery cells.
Nominal capacity - 2200 mAh (above the 2200 stabilityLithium cells is controversial)
Maximum load current - 2.4 amperes max.
Max Discharge Current - 4.6 amps max.
Dimensions (d / h) 18.3 mm (max. 18.4) x 64,9 mm (max. 65.1)
Weight 46,5 g (1.64 oz)
Resistance resistance: less than or equal to 90 Ohms
Cycle efficiency is 80% original capacity at 300 cycles

Well, as already mentioned, asked readers how many cells in the Toshiba Satellite M105-S3041 laptop battery? The battery is rated at10.8 volts and a capacity of 8800 mAh.

As I mentioned above the nominal voltage average is 3.7V. Some manufacturers may use 3.6V and some may use 3.7V. In the case of a laptop battery with 10.8V the nominal voltage rating used is 3.6V. Thus if we divide 10.8V by 3.6V we get 3. Thus 3 cells in a series. We also know that the batteries capacity is 8800 mAh. We know the nominal capacity is 2200 mAh. Therefore if we divide 8800 mAh by 2200 mAh then we get 4 in parallel.

Therefore, we have: 3 cells in series, parallel multiplied by 4 cells are in a total of 12 cells.
