Question from a reader: "How many cells are in the Compaq Presario V5000 series Laptop Battery? The battery is for a Compaq Presario V5000 series and its technical ratings are 10.8 volts 8800 mAh, Lithium Ion."
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…
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: 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 Compaq Presario V5000 series Laptop Battery? The battery is rated at 10.8 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 X 4 cells in parallel equals 12 cells in total.

Upgrade my HP Compaq Laptop Battery from Ni-MH to Li-ion
Ni-Cd, Ni-MH and Li-ion HP Compaq Laptop Battery are all fundamentally different from one another and cannot be substituted unless the laptop has been pre-configured from the manufacturer to accept more than one type of battery chemistry. Please refer to your manual to find out which rechargeable battery types the laptop device supports or use our HP Compaq Laptop Battery Finder above to find all the compatible Laptop Battery for your device. It will automatically list all of the battery chemistries supported by your specific device. If your device does allow you to upgrade the battery from Ni-MH to Li-ion, you will typically get longer run times.
For example, if your laptop uses a NI-MH battery that is 9.6 Volts, 4000mAh and the new Li-ion laptop battery is 14.4 Volt, 3600mAh, then you will obtain longer run time with the Li-ion battery.

Example.
Li-ion: 14.4 Volts x 3.6 Amperes = 51.84 Watt Hours
Ni-MH: 9.6 Volts x 4 Amperes = 38.4 Watt Hours
The Li-ion is stronger and has longer run time.
How can I maximize the performance of my HP Laptop Battery?
There are several steps you can take to help you get maximum performance from your Laptop Battery:Prevent the Memory Effect - Keep the Laptop Battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-ion batteries which do not suffer from the memory effect.
Keep the HP Compaq Laptop Battery Clean - It's a good idea to clean dirty battery contacts with a cotton swab and alcohol. This helps maintain a good connection between the battery and the portable device.
Exercise the Battery - Do not leave the battery dormant for long periods of time. We recommend using the battery at least once every two to three weeks. If a Laptop Battery has not been used for a long period of time, perform the new battery break in procedure described above.
Battery Storage - If you don't plan on using the Laptop Battery for a month or more, store it in a clean, dry, cool place away from heat and metal objects. Ni-Cd, Ni-MH and Li-ion batteries will self-discharge during storage; remember to recharge the batteries before use.
What is the run time of batteryexpress.org.uk's Laptop Battery?
HP Compaq Laptop Battery have two main ratings on them: Volts and Amperes. Because size and weight of Laptop Battery is limited when compared to larger batteries such as car batteries, most companies show their ratings with Volts and Mill amperes. One thousand Mill amperes equals 1 Ampere. When buying a battery, select batteries with the most Mill amperes (or Ah). Batteries are also rated by Watt-Hours, perhaps the simplest rating of all. This is found by multiplying the Volts and the Amperes together. For example:14.4 Volts, 4000mAh (Note: 4000mAh is equal to 4.0 Amperes).
14.4 x 4.0 = 57.60 Watt-Hours
Watt-Hours signifies the energy needed to power one watt for one hour. This HP Compaq Laptop Battery can power 57.60 watts for one hour. If your laptop runs at 20.50 watts, as an example, this Laptop Battery could power your laptop for 2.8 hours.
