Original pack:<\/strong> Dell Type D2VF9<\/strong>, 43Wh<\/strong>, 11.1V<\/strong><\/li>\n
Model fit:<\/strong> Inspiron 15 Series 7548<\/strong>, Regulatory Model P41F<\/strong><\/li>\n
Battery style:<\/strong> Internal, screw-mounted (user-replaceable with care)<\/li>\n
Runtime:<\/strong> Varies with workload\/brightness; restoring a fresh 43Wh pack typically brings back \u201cas-new\u201d runtime<\/li>\n<\/ul>\nCheck stock & warranty \u2192<\/a><\/p>\n<\/section>\n

How to confirm compatibility<\/h2>\n
\n
Shut down<\/strong> the laptop and unplug the AC adapter.<\/li>\n
Remove the bottom cover (see tool list below) to access the battery label.<\/li>\n
Verify the label shows Type D2VF9<\/strong> and 11.1V<\/strong> nominal voltage.<\/li>\n
Match the Type<\/strong>, Voltage<\/strong>, and connector<\/strong> when ordering a replacement.<\/li>\n<\/ol>\n
Tip: Always match voltage printed on your original pack; don\u2019t mix 11.1V and 15.4V families.<\/p>\n<\/section>\n
