Choosing the right laptop battery is not always as simple as picking the brand name. Many laptops from the same brand can use different batteries, even if they look similar from the outside. A Dell laptop battery, HP laptop battery, Lenovo laptop battery or Acer laptop battery may come in several shapes, sizes, voltages and connector types depending on the exact model.
If your laptop battery is no longer holding charge, draining quickly, swollen, or showing “plugged in, not charging”, the first step is to identify the correct replacement battery before you buy one.
Start With Your Laptop Model Number
The easiest place to start is your laptop model number. This is usually printed on a sticker underneath the laptop, inside the battery compartment, or on the original box or invoice.
You may see something like:
HP Pavilion 15
Dell Inspiron 3501
Lenovo ThinkPad T480
Acer Aspire 5
Asus VivoBook 15
When searching online, it is better to search for the full model number instead of only typing “HP laptop battery” or “Dell laptop battery”. For example, searching for “HP Pavilion 15 laptop battery” gives much better results than just “HP battery”.
PartMasters can help you find replacement laptop batteries by brand and model, which is useful if you are not sure which battery fits your laptop.
Check the Battery Part Number
The most accurate way to identify a laptop battery is by checking the battery part number. This is printed on the battery itself. If your laptop has a removable battery, you can usually take it out and look for a code on the label.
Battery part numbers may look like:
HS04
LA04
JC04
L15M4A02
A41-X550A
PA5185U
WDX0R
MR90Y
These numbers are often more useful than the laptop model because the same battery can sometimes fit several laptop models. When buying a replacement laptop battery online, the part number helps make sure you get the correct one.
Check the Voltage and Capacity
Laptop batteries also have technical details printed on the label. The most important ones are usually voltage and capacity.
Voltage may be shown as 10.8V, 11.1V, 14.4V, 14.8V or similar. Capacity may be shown as mAh or Wh, such as 2200mAh, 4400mAh, 48Wh or 56Wh.
The replacement battery should match the correct type for your laptop. A battery that looks similar but has the wrong voltage or connector may not work properly. This is why it is important to compare the details carefully before ordering.
Removable Battery or Internal Battery?
Older laptops often have removable batteries that clip in from the outside. Newer laptops usually have internal batteries fitted inside the laptop casing.
If your battery is removable, it is usually easier to identify and replace. If your laptop uses an internal battery, you may need to open the laptop to check the battery part number. If you are not comfortable doing this, it is better to ask a technician or send the model details to a laptop parts supplier.
PartMasters supplies both removable and internal laptop batteries for different laptop brands and models.
Make Sure the Shape and Connector Match
Laptop batteries are not universal. Even two batteries with similar specifications may have different shapes or connector positions. Before buying, compare the replacement battery with the original battery wherever possible.
Check:
The shape of the battery
The position of the connector
The screw holes, if it is an internal battery
The battery part number
The laptop model compatibility list
This is especially important for internal laptop batteries, where a small difference in shape can stop the battery from fitting correctly.

What If You Are Not Sure?
If you are not sure which battery you need, do not guess. Buying the wrong laptop battery can waste time and money, and in some cases it may not fit at all.
The best option is to send your laptop model number, old battery part number, or a clear photo of the battery label to someone who works with laptop parts regularly.
