What it is

The POWER-FENG SE04XL is a lithium-polymer replacement battery rated at 41.58Wh and 5400mAh with a 7.7V output. It is built for the HP Pro X2 612 G2 and matches part numbers SE04XL, HSTNN-DB7Q, 860724-281, 860724-2C1 and 860708-855. Buyers needing a different voltage or a higher capacity for another device will not be served by this unit.

Behaviour under load

The 5400mAh cell delivers a steady 7.7V supply during extended work sessions rather than a brief peak. Internal protection circuits guard against over-charge, over-discharge and short-circuit events so the pack maintains stable output through a full day of typical use. Systems that demand a higher watt-hour rating or a different cell chemistry will not run correctly on this battery.

Thermals and power

Li-polymer construction keeps internal resistance low, so the pack stays cool during normal charge and discharge cycles with no audible noise. The black casing fits the original battery bay without adding bulk. Users who require active cooling, a higher voltage rail or a ruggedised enclosure for extreme environments should look elsewhere.
