Laptop Battery Cell – Price, Replacement, and Capacity

May 26, 2022   Pageview:59

A laptop is only as useful as its battery. We enjoy the portability because you don't have to be connected to a direct power source all the time.

However, laptop batteries have one problem, just like any other rechargeable battery. They depreciate in terms of capacity and power output.

Your battery will no longer give you the services you expect when that happens. It cannot hold enough power to run for a few minutes.

What can you do then? You will have to replace it. Repairing batteries is often not a very good idea. That leaves you only with the option of replacement.

In this guide, we will try to help you understand this more. We will be discussing the price, replacement, and capacity of a laptop battery.

Laptop Battery Cell Price

Laptop batteries come at different prices. Some are expensive, while others are quite cheap. No matter, you will always find a battery that suits your needs.

The most expensive laptop battery can cost more than $100. The cheapest can cost less than $20.

Here are some of the factors that determine a laptop battery price.

Battery Type

There are several chemistries in the battery market. Most laptops use NiCad and Li-Ion batteries.

NiCad batteries are among the oldest batteries. There are not many left, but you can always find some.

Also, there are NiMH batteries. These are the least expensive of all laptop batteries. Also, NiMH batteries are becoming fewer and fewer on the market.

Just because they are cheap, it does not mean they are useless. Certain applications are quite suitable for such batteries. For instance, if you don't travel a lot and have a direct power source near, you can buy a NiMH or NiCad battery.

Lithium batteries are the most popular type today. The batteries are more powerful, durable, and generally safer than other batteries. As such, you can expect them to be quite expensive.

Even within the lithium family are other smaller subgroups. For instance, we have LiPo batteries, which are better than standard Li-ion batteries. You can expect them to cost a little higher.


Capacity is the amount of energy a battery can store. It is measured in mAh. The higher the rating, the longer the battery can last.

In other words, a battery with a higher capacity will last longer. This means you can enjoy more use time from the battery.

Some replacement batteries come with a higher mAh rating than original brands' batteries. They are still fully compatible with your device, making them a great option.

Batteries with a higher capacity are priced higher. But the price is nothing compared to how much the battery performs. It's, therefore, better to invest in one.


Voltage is another crucial factor to consider when buying laptop batteries. And as you may have imagined already, it affects the price.

Voltage can be defined as the battery's volume of electricity to your laptop. Batteries differ largely in voltage. And many people often confuse it with capacity.

The higher the voltage, the more expensive the battery. It only means you will get more power whenever your laptop needs it. The battery will not strain even under the hardest conditions.

Your Device

Sometimes, the device has more to do with the battery you get than itself. Laptops that are not very common on the market don't have many spare parts. That means even finding a replacement battery is a bit hard.

Other laptops, like Apple laptops, are very delicate when it comes to replacement parts. This means you cannot choose just any battery. Such things can make the batteries very expensive.

You need to research the best battery for your laptop carefully. It's better to buy an expensive one than get one that will end up damaging the machine.


Laptop Battery Cell Replacement

The weakening of batteries over time is one of the biggest frustrations laptop users face. The battery fails to hold a charge.

If your battery could hold a charge for more than two hours, it may reduce to only 20 minutes.

You will need a replacement battery.

Now note that replacement batteries can be quite expensive. Also, there are certain things you will need to know before replacing a laptop battery. Consider the following:

Li-Ion Battery

Lithium batteries can be quite dangerous. You need to be very careful around them because they carry a risk of fire and explosion.

Such batteries will only be operated using charging recommended charging circuits. Misconnecting a li-ion battery in the wrong device is dangerous.

A punctured li-ion battery may produce poisonous smoke. You should find the safest way of dealing with such issues when they occur.

Other Batteries

Batteries like NiMH and NiCad may not be as good in performance as li-ion batteries, but they are safer. These batteries are designed to offer a limited power supply. And they are cheaper.

However, they are not as popular as li-ion batteries. If possible, invest in an expensive replacement battery because it will save you more in the long run.

How to Replace a Battery in Your Laptop

Ensure the battery is fully drained, and then switch off your device.

Open the laptop battery seam with a screwdriver. This might take some time since the cells are often glued together.

You should see four to eight cells in the battery.

Cut the plastic covering carefully using a knife. Make sure you are not exposing the battery. Connect the wires to detach the battery from its charging tray.

Insert the new cells into the plastic case. Put them in the battery tray and restore the wires.

Reassemble the battery and connect it back carefully.

Now you have replaced the battery cells successfully. You can enjoy the new power.

Laptop Battery Cell Capacity

Capacity in a battery means how much electric charge the cells can hold. It is measured ampere-hours. 1 Ah = 10000 mAh. Capacity specifies the capability of the battery to give power to the device.

If you know the capacity and voltage of a battery, you can easily calculate its energy. The operating voltage of a Li-ion battery remains fairly the same over its lifetime. But capacity deteriorates over time.
