40 Wh replacement battery for Dell Latitude

This 40 Wh lithium-polymer pack replaces the original JK6Y6 cell in Dell Latitude 3410 and 3510 models as well as Vostro 5300 5301 5401 5402 5501 5502 machines. It delivers 3550 mAh at 11.25 V and fits the same three-cell form factor. The unit is new and certified to CE UL FCC and RoHS standards.

Capacity and cycle life for daily workloads

The 40 Wh rating supports typical office tasks and web browsing for several hours on a single charge. Rated for more than 500 recharge cycles, the pack maintains usable capacity across extended daily use. Heavy workloads such as sustained video rendering will deplete the reserve faster than light productivity.

The black lithium-polymer housing matches the original dimensions and connector layout for straightforward installation. Integrated circuit protection guards against overcharge over-discharge and short circuits. Compatibility excludes Dell Ins 7300 7306 7500 7506 2-in-1 Black variants so verify the exact model before fitting.

Questions about this item

Will the JK6Y6 40Wh battery fit alongside the original charger in my Dell Latitude 3410?

Yes, the JK6Y6 is a direct replacement for part numbers C5KG6, CF5RH and H5CKD, so it works with the original Dell charger supplied with the Latitude 3410.

How can I confirm the JK6Y6 3550mAh battery is functioning correctly after installation?

The laptop should power on without the AC adapter, show a charging icon when plugged in, and report a design capacity near 40 Wh in the BIOS or operating system battery report.

Does the JK6Y6 11.25V pack ship with installation tools or only the battery itself?

The package contains the JK6Y6 battery unit only; screwdrivers, opening picks and any adhesive strips required for the Dell Vostro or Inspiron chassis must be sourced separately.
