How to Remove Laptop Battery and Identify References/Specifications

You will need to perform a simple and easy disassembly of your laptop. You will need to recognize the battery, its capacity and specificities to replace it with the same battery or one that is 100% compatible with your laptop.

There are different ways of accessing the battery depending on the type of laptop you have:

Laptops with a Removable Battery

These are becoming less common since newer laptops tend to be more compact but if your laptop has a removable battery, follow this simple procedure to remove the battery:

  • Disconnect your PC from any AC outlet and turn it off.
  • Turn your computer over and find the latches that hold the battery
  • Open the latches and remove the battery

Laptops Without a Removable Battery

Since the latest generations of laptops are very compact, the batteries are often directly attached to the chassis and not easily accessible. Here is a common procedure to access the battery for this type of laptop:

  • Disconnect your PC from any AC outlet and turn it off.
  • Turn your computer over and remove the various screws present (on the bottom case).
  • Using a standard screwdriver or a card, gently wedge open the space separating the bottom case of the laptop from the keyboard.
  • Beware; when you attempt to separate the keyboard from the bottom case, a cable connects the two. You will need to delicately disconnect one of its connectors before separating.
  • The battery is usually located under the keyboard, along your screen and is also connected by a cable.
  • Unplug the cable, remove the old battery, replace it with the new one and then carefully repeat the steps in reverse to reassemble the computer.

A lot of information is printed directly on the battery as to its type, model, capacity and voltage.

Today the majority of batteries in consumer electronics are lithium polymer (Li-Po) or lithium- ion (Li-Ion).

In addition to the type battery, there are three things to note:

  • The voltage (in Volts or V): The nominal voltage of the battery which is the number of Volts that your laptop requires to function must be the same in the new battery.
  • The capacity (in milliampere-hour or mAh): represents the autonomy of your laptop, the higher the mAh of the battery the longer your battery will stay charged (higher autonomy).
  • The power (in watt-hours or Wh): Wh is the product of the two previous values (mAh X Volts), it indicates the power of the battery. You can use a battery with more power (Wh) than the original one as long as it has the same voltage rating and is compatible with your laptop.

As for the capacity of the battery, if a high capacity battery exists that fits your model, nothing prevents you from using it to increase your autonomy.

Warning, increasing power capacity (mAh) too much is not recommended. Your charger may not be able to recharge it, or it just may take a very long time (ex.10 hours instead of 2).
