How to Find the Model of My Laptop Computer?

  1. Open the laptop and check the area near the keyboard first. Manufacturers commonly print the computer model (such as Aspire 4736G for a Acer computer) on or near the keyboard.
  2. Close the laptop and flip it over to read the back. Look for the laptop computer model name printed on the product tag, which also contains a bar code.
  3. Check the bottom of your laptop for a service tag or similar number. Log onto your laptop manufacturer's website, go to the support area and enter your service tag number. This will bring up complete data about the model name of the laptop, as well as the date of manufacture and warranty information.
  4. Click the "Start" menu, go to "Accessories" and then "System Tools" (applies to Windows systems). Select "System Information" to bring up a dialog box listing complete information about your laptop, including the "System Model."

How can I find my battery’s part number?

  1. Make sure the laptop is unplugged and turned off, and that the battery has cooled.
  2. Flip the laptop upside down. Push the battery latch to the left "unlock" position. While holding the latch in this position, slide the battery out of the computer.
  3. Look for the serial number that is printed on the label on the back of the battery. The serial number will be a combination of some letters and numbers that more conspicuous.
  4. For you convenience, please refer to the pictures below to see an example for a Aspire 4741G part number:

What is a "part number"?
A part number is a code the uniquely identifies an inventory item. The purpose of this code is to help us refer to that specific item without knowing additional information such as manufacturing machine, machine brand, inventory part size etc.

What is battery capacity?
Battery capacity can be described as the electrical energy content, which is usually expressed in milliAmpere-Hours (mAH). This is determined by the amount of electrical energy the battery has capacity to deliver – under stated conditions of temperature, rate of discharge and final battery voltage, all over a specific time period. As one might guess, the higher the battery capacity rating, the higher the MaH, and the longer the battery will last. Thus, for laptop computers and other portable devices that are used for long periods of time, batteries with higher capacities are preferred.

What is Volt?
A volt is a measure of electrical pressure or force. Referred to as “V” for voltage, different volts or voltages will be found in batteries of different chemistries. For instance, NiCd and NiMH batteries are nickel based, providing a cell voltage of approximately 1.2 V, while a Li-ion cell provides 3.6V/3.7V.
With that said, the voltage of two battery cells of the same chemistry is always the same. While their capacities may differ, the voltage always remains the same. Likewise, it is crucial that the voltage of a cell or a battery pack always mirrors that of the voltage requirement of the device in which it is used. If there is a difference between the two, the device will malfunction and enough malfunctions may also cause permanent damage.

Are Li-ion batteries affected by “Memory Effect”?
Quite simply, no – Lithium ion batteries are not affected by “Memory Effect.” Such an action would result in a drop in the capacity or voltage of a rechargeable battery. While Li-ion batteries are not impacted by “Memory Effect,” it does impact NiCd and NiMH because they are nickel-based. Thus, laptop users can become quite rustrated with unexpected downtimes.

What is self-discharge?
When a battery loses its charge when it’s not in use, it’s referred to as a self-discharge. If a battery sits without being used, it will lose its charge, and this self-discharge is at its highest following a full charge of a battery at full capacity. There are other factors that impact the rate of self-discharge, including temperature of where the battery is stored and even the humidity present. And this is true regardless of battery type or chemistry. Li-ion batteries have the lowest self-discharge rate – 5% to 10% per month; quite low compared to 20% of the NiCd, 30% of the NiMh.

What is cycle life of a battery?
When you calculate the number of times a battery can be charged and discharged before it fails, you are measuring battery life cycle. Thus, one battery cycle is defined as a full charge that is followed by a full discharge.

What is battery life?
Battery life, as one might suspect, is a measure of the number of battery cycles a battery can provide before it “dies” and needs to be completely replaced. Battery life varies between chemistries, but Li-Ion batteries generally provide around 500-700 charge/discharge cycles.

What precautious should be taken when storing laptop batteries?
Heat and metal objects do not act well with laptop batteries. Best practices include removing laptop batteries and storing them in a dry and cool storage space. When stored, batteries should be discharged to 40%. Prolonged storage of Li-ion batteries for more than three months is not recommended.

How can I find the laptop battery specifications?
There are several different types and sizes of laptop batteries. To determine what laptop battery you have, remove the battery from the laptop and look at the bottom or top of the battery.
As can be seen in the picture to the below this Acer battery shows that it's a Li-ion battery, has a model number of Li-ion, rating of 11.1V, 4400mAH/48Wh, Part number "AS10D71"

Does high capacity battery fit for my laptop? Like capacity of 6600mAh, 7200mAh, 7800mAh, 8800mAh.
Battery capacity can be different ie 4400mAh, 4800mAh, 5200mAh, 6600mAh, 7200mAh, 8800mAh or similar like this. It will still work in your computer without any problem. Higher capacity works for longer time(run time/discharge time) Only Some of the longer capacity batteries like 6600mah or 8800mah are bigger in size and sticks out of battery slot but they will still work in your computer.
