Product Description
The ONEXPLAYER Mini Pro shipped in two main CPU configurations — Ryzen 7 5800U and Ryzen 7 6800U — both housed in the same 7-inch chassis and using the same battery cavity. The original pack, P/N LR386387-3S, is a 3-cell series Li-ion assembly rated at 11.55V nominal and 48.51Wh total energy, which works out to approximately 4200mAh at pack level.
Repair depot data from 2023–2025 shows this is one of the more consistently reordered handheld gaming battery SKUs in Western markets. Users running sustained gaming or emulation workloads typically see measurable capacity loss within 18–24 months, which keeps aftermarket demand steady across North America, Europe, and Japan.
