Product Description
The GPD WIN Mini is a compact Windows handheld built around AMD Ryzen 7000-series processors. Its battery sits in a tight thermal envelope — which puts strict demands on cell consistency, internal resistance, and packaging dimensions. The 4139D5 is the OEM-designated battery for this platform, and sourcing a poorly spec’d replacement is a fast way to trigger thermal warnings or shortened runtime in the field.

Features & Advantages
✅ Exact-Fit OEM Dimensions
The 4139D5 is a 3S1P Li-ion pack built to the original GPD mechanical envelope. Connector pinout and housing geometry match the mainboard socket directly — no adapter, no modification needed during installation.
✅ Stable 44.24Wh Usable Capacity
Rated at 3810mAh / 44.24Wh at 11.61V nominal. Under continuous load typical of Ryzen 7 7840U gaming scenarios (15–20W TDP), this translates to roughly 2–3 hours of active use — consistent with OEM factory spec.
✅ 3-Cell Li-ion Construction
Three high-consistency lithium-ion cells in series. Cell matching at the pack assembly stage keeps voltage balance within ±20mV, which directly affects cycle life and BMS behavior. Low-grade packs with mismatched cells degrade noticeably after 50–80 cycles.
✅ Grade-A Cell Sourcing, Batch-Level QC
Each production batch goes through capacity grading and internal resistance screening before assembly. This matters for B2B buyers who are fielding units to end customers — you don’t want variance-driven warranty callbacks.
✅ B2B Direct Supply — No Intermediary Markup
We supply direct from the production facility. Sample orders are available for evaluation before bulk commitment. Lead time for standard stocking quantities is quoted per order volume — contact us for a factory price sheet.

FAQ
Q1: What devices is the 4139D5 battery compatible with? A: The 4139D5 is the OEM-designated battery for GPD WIN Mini 2023, 2024, and 2025. It is not cross-compatible with other GPD models such as the WIN 4 or WIN Max 2, which use different packs with distinct voltages and connector pinouts.
Q2: Is the 4139D5 a direct drop-in replacement — no modification required? A: Yes. The physical dimensions, connector type, and BMS communication protocol match the original GPD mainboard. Standard swap with a Phillips screwdriver; no soldering or firmware changes needed.
Q3: What is the expected cycle life of this battery? A: Under normal use conditions (charge to 80–100%, discharge to 10–20%), a Grade-A cell pack typically holds above 80% of rated capacity after 300–500 full charge cycles. Actual lifespan varies with charge habits and ambient temperature.
Q4: Do you offer samples before bulk orders? A: Yes. Sample units are available for engineering evaluation and QC testing before you commit to a bulk purchase. Contact our sales team with your target quantity for sample pricing and lead time.
Q5: What is the MOQ and typical lead time for bulk orders? A: MOQ and lead time depend on order volume and whether stock is available from our current production run. We’ll quote both figures when you submit an inquiry. Standard stocking orders ship within a competitive window from our factory.
Q6: Does the battery require a break-in cycle after installation? A: It’s good practice to run 2–3 full charge/discharge cycles after initial installation to allow the BMS to calibrate state-of-charge readings accurately. This is standard procedure for any new Li-ion pack and is not unique to this model.
