Dr. Battery laptop battery 3600 mAh 15.2 V for Dell Inspiron 13 7300 2-in-1

Battery replacement for select Dell Inspiron

This Dr. Battery Professional Series unit replaces the original Dell 3-cell lithium-polymer pack rated at 15.2 V and 3600 mAh. It fits multiple Inspiron 13, 14 and 15 models plus Vostro 13 and 14 chassis. The battery targets professionals and everyday users who need dependable mobile power without buying a new laptop.

OEM-grade cells and integrated protection

Built with OEM-grade cells, the pack delivers stable voltage output and long cycle life for consistent runtime. On-board circuitry guards against over-charge, over-discharge, overheating and short-circuit events, protecting both the battery and the notebook during daily use and transport.

Straightforward swap with part-number check

Installation follows the standard Dell bottom-cover removal process; the pack slides into the original bay and reconnects to the existing cable. Most issues arise when buyers order without confirming their original part number — such as 7T8CD, 9077G, H5CKD or TXD03 — and voltage, leading to an incompatible fit.
