How can I confirm a replacement laptop battery will fit?
The best way is to match the part number printed on your current battery.
Then verify the voltage, and compare the battery shape plus connector location with the product photos and specs.
How can I find my laptop model on a Windows laptop?
If you are using a Windows laptop, you can find your laptop model using
System Information:
• Step 1: Press Windows + R to open the Run window.
• Step 2: Type msinfo32 and click OK.
• Step 3: In the System Summary section, find
System Model in the right pane.
This model information helps ensure you select the correct replacement battery.
Where do I find the battery part number?
Power off the laptop, unplug the charger, and remove the battery if it’s removable.
The part number is printed on the label on the battery itself—use that to confirm compatibility.
Can I use a battery with a different voltage?
In most cases, no—battery voltage should match the original.
Some labels are equivalent (10.8V = 11.1V, and 14.4V = 14.8V), but other voltage differences are not compatible.
What should I check before buying a replacement online?
Start with the original battery part number and voltage.
After that, compare size and shape, connector type and position, latch/clip placement, and orientation using product photos and details.
Can I search by laptop model instead of battery part number?
The laptop model helps narrow results, but the battery part number is more accurate.
One laptop model can use multiple battery versions, so matching the printed part number is recommended.
Any quick tips to improve laptop battery runtime?
Turn on Power Saver/Battery Saver, lower screen brightness, close unused apps and tabs,
disable Wi-Fi/Bluetooth when you don’t need them, and keep vents clear to reduce heat.
Picking the correct replacement battery (and adapter, if needed) matters for safety and performance.
Battpit stocks a wide range of compatible part numbers and models across major laptop brands.
Use the checklist below before you place your order:
1. Identify Your Laptop Model
Check the label on the bottom of the laptop or your system information for the exact model.
If you’re purchasing an adapter, verify the input requirements shown on your laptop label (voltage/current).
2. Match the Battery Part Number
Always shut down the laptop before removing the battery.
The part number printed on the battery label is the most reliable way to confirm the correct replacement.
3. Common Part Number Examples
Brands often use predictable formats. Here are a few examples to help you recognize them:
HP / Compaq: 123456-001
Sony: PCGA-BP12, VGP-BP1
Dell: 312-1234, 1234P
IBM / Lenovo: 02K1234, 08K1234
Toshiba: PA1234U-1BRS
4. Compare the Physical Fit
Double-check the overall shape, connector type and connector position,
plus the latch/lock location and orientation. Compare these with product photos before ordering.
5. Voltage Notes
Some laptops have multiple battery options with different voltages (for example, 11.1V vs 14.8V).
These are not interchangeable. Always match the voltage printed on your original battery.
Li-ion 10.8V is equivalent to 11.1V.
Li-ion 14.4V is equivalent to 14.8V.
