Direct replacement for Latitude 3340 3350 V131 Gen2

This 6-cell lithium-ion battery matches the original 11.1V 65WHR specification and fits Dell Latitude 3340, 3350 and V131 second-generation models. It restores full mobile runtime for users whose factory pack no longer holds a charge. The unit is brand new and built to the same electrical parameters as the OEM part numbers listed.

Stable output with certified safety circuits

Integrated protection circuitry regulates voltage and current during charge and discharge cycles, keeping the pack within safe thermal limits. Low self-discharge chemistry preserves stored energy when the laptop is left unused for weeks. CE, FCC and RoHS certifications confirm compliance with electrical safety and substance restrictions.

Ready to install with no extra tools

The battery ships as a single black 6-cell module that seats directly into the existing bay on compatible Dell chassis. No separate cables, brackets or driver discs are included because the original hardware accepts the pack natively. Users simply swap the old unit and resume work.

Questions about this item

How do I install the 6-cell 11.1V battery in my Latitude 3340 without damaging the latch?

Power off the laptop and unplug the charger. Slide the release latch to the unlock position, remove the old pack, align the new YFDF9 battery with the guide rails, press firmly until the latch clicks back into the locked position, then reconnect AC power for the first charge.

What replacement will this 5856mAh pack need over time?

The lithium-ion cells degrade with each charge cycle; when run-time drops below what your workload requires, order another YFDF9-compatible 65WHR pack matching part numbers such as 451-BBIZ or 3NG29.

What limit appears first during sustained use of this 65WHR battery?

Capacity fade is the first limit — after many cycles the 11.1V pack delivers less usable energy per charge, so run-time shortens before voltage stability or thermal protection becomes an issue.
