FOCUSTEC 11.4V 42Wh replacement battery

This 3-cell lithium-polymer pack delivers 11.4 volts and 42 watt-hours of capacity. It is built as a direct replacement for a wide range of Dell Inspiron 13, 14, 15 and 17 models across the 5000 and 7000 series, plus select Vostro 3480, 3490, 5468, 5471, 5568 and Latitude 3490 units.

Check your exact model number before ordering

Dell uses several different battery designs within the same marketing series such as Inspiron 15 7000 or Vostro 15 5000. Verify the part number printed on your original battery or consult the service manual to confirm this 11.4V 42Wh unit matches your chassis. The connector layout and physical dimensions must align with the specific sub-model listed in the compatibility data.

Replaces a worn or failed original Dell pack

When the factory battery no longer holds a useful charge or triggers a capacity warning, this new 42Wh cell restores full mobile runtime. It is rated for up to 500 recharge cycles over its service life. The upgrade is worthwhile when the laptop otherwise meets your needs but is tethered to an outlet due to degraded capacity. It is not for users needing higher capacity than 42Wh or a different voltage.

Questions about this item

Does the FOCUSTEC 11.4V 42Wh battery ship with any tools or cables, or must I buy them separately?

The battery is supplied as a standalone 3-cell lithium-polymer unit; no screwdrivers, cables or additional hardware are included in the package.

My Dell Inspiron 15 7000 has several sub-models — how do I confirm the 42Wh version is the correct one?

Match your exact model number — such as 7560, 7569, 7570, 7573, 7579, 7580 or 7586 — against the compatibility list; only those listed are supported.

What does the 42Wh rating actually deliver in daily use on a compatible laptop?

The 42 watt-hour capacity typically provides several hours of mixed workload runtime on supported Inspiron 13, 14, 15 and 17 models, varying with screen brightness and applications.
