-20°C to 60°C
Operating Range
Engineered for cold-weather discharge. Maintains capacity in sub-zero temperatures where standard Li-ion cells lose 30-50% performance.
500+
Cycles
Premium 18650 cells rated for 500+ full charge-discharge cycles. Built for season-after-season reliability in heated apparel.

How Long Does a Heated Jacket Battery Last?
Runtime depends on battery capacity (Wh) and heat level selected. Formula: Runtime (hours) = Battery Energy (Wh) ÷ Power Draw (W). Here's what to expect from common configurations:
| Battery (7.4V) | Energy (Wh) | Low (5W) | Medium (8W) | High (12W) |
|---|---|---|---|---|
| 2600mAh | 19.2 Wh | ~3.8 hrs | ~2.4 hrs | ~1.6 hrs |
| 5000mAh | 37 Wh | ~7.4 hrs | ~4.6 hrs | ~3.1 hrs |
| 7500mAh | 55.5 Wh | ~11 hrs | ~6.9 hrs | ~4.6 hrs |
| 10000mAh | 74 Wh | ~14.8 hrs | ~9.3 hrs | ~6.2 hrs |
| 14400mAh | 106.6 Wh | ~21 hrs | ~13.3 hrs | ~8.9 hrs |
Actual runtime varies by heating zone count, ambient temperature, and garment insulation. Low/Med/High power draw based on typical 3-zone heated jacket. Contact us for runtime calculations specific to your product design.

ISO 9001Heating Battery FAQ
What voltage battery do heated jackets use?▼
Most heated jackets and vests use 7.4V DC batteries. This provides optimal heat output while keeping the battery compact and safe for wearable use. Some lower-power heated accessories like pillows use 5V USB output instead.
What is the MOQ for heating battery OEM?▼
MOQ starts at 500 units for standard OEM models with custom logo. Custom ODM with new connector types or capacity tuning: 1,000-2,000 units. Sample turnaround: 3-7 days for standard, 10-15 days for custom.
Can you match our existing heated jacket connector?▼
Yes. WOWOHCOOL supports custom connector matching including DC barrel connectors (3.5mm, 5.5mm), magnetic pogo pins, and proprietary connectors. Send us your existing battery or connector sample and we'll match it exactly.
What is the operating temperature range?▼
WOWOHCOOL heating batteries operate from -20°C to 60°C, making them suitable for extreme cold weather heated apparel applications. Discharge performance is optimized for low-temperature environments where standard Li-ion cells lose 30-50% capacity.
How long does a 7.4V 5000mAh heated jacket battery last?▼
A 7.4V 5000mAh battery provides 37Wh of energy. On a typical 3-zone heated jacket: approximately 7.4 hours on low (5W), 4.6 hours on medium (8W), or 3.1 hours on high heat (12W). Actual runtime varies by heating zone count, ambient temperature, and garment insulation.
Can heated jacket batteries be taken on airplanes?▼
Yes. All WOWOHCOOL heating batteries are under 100Wh (the largest 14400mAh model is approximately 106Wh at maximum — we can configure capacity to stay within the 100Wh IATA carry-on limit). UN38.3 certified with full MSDS documentation for airline compliance. Batteries under 100Wh are permitted in carry-on luggage without pre-approval.
What certifications do heated clothing batteries need for Amazon?▼
Amazon US requires UL certification (UL 2054 or UL 1642) for lithium batteries sold on their platform. Additionally, UN38.3 is needed for shipping, and FCC for the product listing. WOWOHCOOL provides CE/FCC/RoHS as standard and assists with UL certification application and testing coordination.
