Match the part number and electrical specification—not only the laptop brand.
A replacement laptop battery should match the exact laptop model or supported battery part number, connector, voltage, cell layout and physical shape. Similar-looking batteries can still be incompatible.

Frequently asked questions
Can I buy a battery using only the laptop brand and screen size?
No. Use the exact laptop model and preferably the battery part number printed on the existing battery.
Is the same voltage enough to confirm compatibility?
No. Part number, connector, shape, mounting points and laptop support also matter.
Can the store promise a battery runtime?
Runtime varies with capacity, health, screen brightness, workload and power settings. Ask for the available test information for the exact unit.
