Replacement battery for Dell XPS 14 15 17

This 9-cell lithium-ion pack delivers 11.1V and 90Wh of capacity. It fits Dell XPS models including 1591 L501x L502x L401x L701x 3d L702x L721x J70w7. The unit is brand new from the manufacturer and rated for about 500 recharge cycles over its lifespan. Built-in overcharge and discharge circuit protection helps safeguard the laptop.

Certified safety and drop-in fit

The battery carries CE FCC and RoHS certifications confirming compliance with recognized safety standards. It replaces original Dell part numbers 312-1123 312-1127 453-10186 J70W7 JWPHF WHXY3 without requiring modifications. No extra cables, software or mounting hardware are included in the package. Installation follows the standard battery swap procedure for the listed XPS chassis.

High-capacity runtime for daily workloads

The 90Wh rating provides extended runtime compared to lower-capacity alternatives, supporting typical office tasks, web browsing and media playback through a full workday. Heavy sustained loads such as rendering or gaming will deplete the charge faster and may require access to mains power sooner. Users needing multi-day autonomy without charging should consider carrying a spare pack or external power bank.

Questions about this item

How many charge cycles can the 9-cell 11.1V 90Wh battery deliver before it needs replacement?

The battery is rated for about 500 recharge cycles over its life, so plan on a replacement once you approach that figure.

What is the first limit reached when the battery runs continuously at full load?

The 90Wh capacity sets the runtime ceiling; once the stored energy is depleted the laptop will shut down or throttle.

Does the 9-cell pack run hotter or draw more power than the original 6-cell during all-day use?

It uses the same 11.1V lithium-ion chemistry with overcharge and discharge protection, so heat and power draw stay comparable to the factory pack.
