Q: Where can I find the battery part number?

Shut down the laptop, unplug power, remove the battery (if removable), and read the label printed on the battery itself. That part number is the best way to confirm compatibility.

Q: Are different battery voltages interchangeable?

No. You must match the voltage on your original battery. Note: 10.8V equals 11.1V, and 14.4V equals 14.8V.

Q: Can I use my laptop model number instead of the battery part number?

You can use a laptop model number to narrow it down, but the battery part number is more precise. One laptop model can support multiple battery types, so the printed battery part number is best.

Laptop Battery FAQs How To Find The Correct Battery?

How do I know if a laptop battery will fit my device?

The most reliable method is matching the part number printed on your original battery. Also confirm the voltage and compare the battery shape and connector position with the product photos and specifications.

Where can I find the battery part number?

Shut down the laptop, unplug the power adapter, remove the battery if it is removable, and read the label printed directly on the battery. This part number is the best way to confirm compatibility.

Are different battery voltages interchangeable?

No. You must match the voltage shown on your original battery. Note that 10.8V equals 11.1V, and 14.4V equals 14.8V, but other voltage differences are not compatible.

What should I compare before ordering a replacement battery online?

Compare the original battery’s part number and voltage first, then check the size and shape, connector type and location, latch position, and orientation against the product photos and specifications.

Can I use my laptop model number instead of the battery part number?

You can use the laptop model number to narrow down options, but the battery part number is more precise. A single laptop model can support multiple battery types, so matching the printed battery part number is best.

What quick settings can help extend laptop battery life?

Enable Battery Saver or Power Saver mode, reduce screen brightness, close unused apps and browser tabs, turn off Wi-Fi or Bluetooth when not needed, and avoid heat by keeping the laptop vents clear.

Choosing the correct replacement battery or adapter is critical for safety, performance, and compatibility. DrBattery.com carries over 120,000 compatible models and part numbers for major laptop brands. Follow these steps before placing your order:

1. Check Your Device Information

Look at your device’s owner’s manual or label on the bottom of your laptop. Both should show the brand and exact model number.
If you are buying an adapter, confirm the model number, input voltage, and current listed on your device label.

2. Verify the Original Battery Part Number

Always shut down your laptop before removing the original battery. On the battery label, you will find a part number. This part number is the most reliable way to ensure compatibility.

3. Recognize Common Part Number Formats

Major manufacturers use standard codes. Here are some examples:

HP / Compaq:
123456-001

Sony:
PCGA-BP12, VGP-BP1

Dell:
312-1234, 1234P

IBM / Lenovo:
02K1234, 08K1234

Toshiba:
PA1234U-1BRS

4. Compare the Physical Details

Check the size, connector type, latch position, and orientation of your original battery. Compare these details with the product photos on our website before ordering.

5. Watch Out for Voltage Differences

Some models have two different voltage options — for example, 11.1V vs. 14.8V. They are NOT interchangeable. Always confirm the voltage printed on your original battery.

A Li-Ion battery labeled 10.8V is the same as one labeled 11.1V.
A Li-Ion battery labeled 14.4V is the same as one labeled 14.8V.
