BoYata MN79H 55Wh 11.55V Battery 2 in 1 accessory

Replacement Battery for XPS 13

The BoYata MN79H is a 55Wh 11.55V lithium-ion pack built to replace the original cell in Dell XPS 13 Plus 9320, XPS 9320, XPS 13 9340, 9345 and 9350 2024 models. It matches part numbers 2FVJM, J7H5M, 0J7H5M, NXRKW and 0NXRKW. The three-cell unit carries UL, CE, FCC and RoHS certifications and includes short-circuit, overheat and overload protection. Buyers who need a higher-capacity pack or a battery for a different laptop line cannot use this model.

Installation Requirements

The battery fits inside the existing chassis and connects to the motherboard with the original connector. You must open the rear cover to verify the installed battery model before ordering. After fitting the pack, secure the connector firmly and charge with the laptop’s standard power adapter. The design frees you from sourcing a separate external charger or docking station. Builders who prefer a user-swappable module without tools or who need a second battery for hot-swap operation will not find that capability here.

Sustained Operation Behaviour

The 4524mAh cell delivers stable current and low self-discharge during extended work sessions. EPYOBW testing confirms true rated capacity under continuous load rather than only in short bursts. Condition the new pack by discharging to five percent, then complete three to four full charge cycles to wake the chemistry. Users who routinely run the laptop at maximum processor and graphics load for many hours without mains power may see reduced runtime compared with light productivity use.
