After a few years, a laptop battery must be replaced. How long it takes for you to replace your laptop battery depends on the brand, quality and use of the laptop battery. Here you will find information about how to replace a laptop battery, how you know it needs to be replaced and what to look out for when replacing the battery.
When do you need to replace a laptop battery?
If the laptop indicates it
Based on the condition of the battery, your laptop will indicate over time that the battery must be replaced. You will usually receive the message ‘Consider replacing the battery’. This message is based on the remaining maximum capacity of the battery and the number of charging and discharging cycles that the battery has had. When you receive this message, you can assume that the battery really needs to be replaced.
If the battery only lasts a very short time
A battery usually lasts less and less. This is because the capacity is slowly declining, but also because the laptop is generally less efficient. This is due, for example, to background software that loads the processor or dust in the laptop that loads the cooling, which means that it consumes more power. If the battery lasts less and less, check if the laptop is dust-free and if unnecessary background software is running. It can also be worthwhile to enable power saving of the laptop through the power management. If all this does not help, the battery needs to be replaced.
If the battery has lost a lot of capacity
The remaining capacity of the battery can be read with software from the manufacturer of the laptop. Some manufacturers do not provide this software as standard. For example, you can use Battery Care to measure capacity. If the capacity of your battery has fallen very far, it may be worth buying a new battery so that you can use your laptop for longer without power.
If the battery is no longer recognized
If the battery or laptop battery used to work well but is no longer recognized, it has failed in most cases. This may be due to wear or, for example, to a current peak that has caused a cell to fail. In this case you can try to remove the battery from the laptop and place it again. In some cases the battery will work again. If the battery does not do anything anymore, it is advisable to replace it. In this case, Windows often displays a red cross through the battery icon at the bottom right of your desktop.

Which battery should I purchase if I am going to replace my laptop battery?
It is best to search on the basis of a part number on the laptop battery or on the basis of the model number of your laptop. Laptop manual booklets always guide users to purchase suitable accessories such as AC Adapter, Battery, Hard drive, RAM etc. You can also use the handy brand navigation with which you can get an overview of all available laptop batteries for your laptop model based on brand, series and model.
Many laptop batteries have a part number. You will often find this at the top left of the laptop battery. An example of Acer is AS10D3. An example of HP is MU0.
You will usually find the laptop model on the bottom of the laptop on a sticker. Usually it is preceded by Model. An example of a laptop model is, for example, N551JQ (Asus), 15-g085nd (HP) or V5-571G (Acer). You can enter this model in the search function or you can find the right battery for your laptop model via the brand navigation.
All batteries are nowadays lithium-oin or lithium-polymer. You no longer have to pay attention to this because older, alternative battery materials are no longer in circulation and are no longer sold for laptops.
So pay attention to the following points when you want to replace your laptop battery:
- The part number of the battery or model number of the laptop is on the site
- The voltage corresponds – 7.4V-7.6V is equal – 10.8V-11.1V is equal – 14.4V-14.8V is equal
- The capacity of the battery – this determines the battery life in hours and minutes
- The shape on the image corresponds to your battery
