Laptop batteries: find the compatible replacement

A new battery can restore mobility to a laptop whose current battery runs down quickly, will not charge or has deteriorated. The catalogue is organised by brand and family, while the definitive match comes from the original battery part number.

How to choose the correct reference

Compatibility is not determined by the brand or device family alone. Before ordering, compare the following details with the battery or part already fitted:

• Full part number and alternative codes printed on the battery.
• Nominal voltage and capacity in Wh or mAh.
• Connector, pin count and cable position.
• Dimensions, shape, fixing points and position inside the laptop.

Buy after a clear technical check

Search by battery part number first. Then check the complete laptop model and every technical detail. A partial match does not prove compatibility, particularly where a laptop range has several internal revisions.

If you are unsure, use the exact reference printed on the original battery or component. Check the full device model and its specific variant as well. This prevents returns and avoids fitting a part that looks similar but is electrically incompatible.

Frequently asked questions

Where can I find the battery part number?

It is normally printed on a label on the battery. Access to an internal battery should follow the device manufacturer’s instructions.

What does capacity in Wh mean?

Watt-hours state the energy stored and help compare expected runtime between batteries of the same voltage and compatibility.

Check availability, price and delivery information on each product page. Make the final choice from the reference and specifications, not appearance alone.
