Key Factors in Battery Selection
Not all batteries are created equal. Pay close attention to these specifications to find the right match.
| Specification | What to Look For |
|---|---|
| Model Number | This is the most critical identifier. Find it on the original battery’s label (e.g., L0XS2A0, PA-1650-05). |
| Compatibility | Ensure the battery is listed as compatible with your specific laptop make and model (e.g., Dell Latitude 5490, HP ProBook 450 G5). |
| Voltage (V) | Must match your original battery’s voltage (e.g., 11.1V). Using the wrong voltage can damage your laptop. |
| Capacity (mAh/Wh) | A higher mAh (milliamp-hours) or Wh (Watt-hours) rating generally indicates a longer battery life. |
| Chemistry | Most modern laptops use Lithium-Ion (Li-ion) batteries. Ensure the chemistry matches. |
How to Find Your Laptop’s Battery Model
- Check the Old Battery: Power down and remove the battery. The model number is almost always printed on a sticker on the battery itself.
- Check System Information (Windows): Type “System Information” in the Start Menu. Under “Components” -> “Battery,” you may find the battery name.
- Check Your Laptop’s Manual: The user manual or specification sheet often lists the supported battery model.
