Two variants require visual check

Dell ships two different batteries for the same model numbers and they are not interchangeable. Buyers must compare the physical shape and connector layout of their existing battery with the product photos before ordering. Installing the wrong variant will prevent a proper fit and electrical connection.

CE and RoHS certified with one-year cover

The pack carries CE and RoHS marks confirming compliance with European safety and environmental standards. A one-year replacement warranty covers defects in materials or workmanship. No additional software, cables or tools are bundled with the battery.
