KingSener RYXXH 11.1V 38WH Laptop Battery for Dell Latitude 12 5000 11 3150 3160 E5250 E5450 E5550 M3150

Drop-in replacement for Dell Latitude 11

This 11.1V 38WH lithium-polymer pack fits Latitude 11 3150 3160 and Latitude 12 5000 models including E5250 E5450 E5550. It matches part numbers RYXXH 09P4D2 9P4D2 05TFCY 0YD8XC so installation requires no adapter or firmware change. The black cell block sits in the original bay and locks with the existing latch.

Runs cool with no moving parts

Solid-state chemistry means zero fan noise and no mechanical wear during daily charge cycles. The 38 watt-hour capacity delivers typical office runtime without increasing the pack thickness or weight beyond the factory design. Normal use sees the battery stay at ambient temperature while the laptop manages its own thermal profile.

Replaces swollen or end-of-life original packs

Owners of the listed Latitude models whose factory batteries no longer hold charge can restore full mobility with this unit. It is not suited for users who need extended capacity beyond 38WH or who require a hot-swap secondary battery since the chassis supports only one internal pack.
