Check your current battery before ordering

Confirm the model label on your existing pack matches one of the listed Dell part numbers. Verify that your laptop chassis is a Latitude 14 5420, Latitude 15 5520 or Precision 15 3560; other Dell series use different connectors and mounting points. Ensure the original battery voltage reads 15.2V so the replacement will communicate correctly with the system firmware.

Sustained use and cycle life

The lithium-ion cells are rated for up to 500 full recharge cycles while maintaining usable capacity. Under continuous load the pack delivers steady 15.2V output without the voltage sag seen in aged or lower-grade cells. UL, CE, FCC and RoHS certifications confirm the battery meets safety standards for prolonged daily operation in office or field environments.
