The provided specifications do not state an operating temperature range for the USB Rechargeable Battery. Require CHUNG PAK to confirm the tested operating temperature range for the intended device and usage conditions before approval. The available data identifies high capacity, cycle life, low self-discharge, no memory effect, and high safety standards, but it provides no temperature limits.
Operating temperature is a required product-selection parameter for the USB Rechargeable Battery, yet the supplied data does not specify a minimum or maximum value. A technical requirement should therefore remain open until CHUNG PAK provides a temperature range supported by its product documentation or testing records.
The battery is listed for high-power and medium-power equipment. Examples include high-power flashlights, searchlights, portable speakers, industrial sensors, emergency lights, desk lamps, camping lanterns, Bluetooth speakers, portable recorders, and electronic toys. These applications should be evaluated individually because the supplied information does not assign a temperature range to any specific use case.
The listed product parameters are high capacity, cycle life, low self-discharge rate, no memory effect, high safety standards, and environmental consideration. These characteristics describe the intended product profile, but they do not establish operating, charging, storage, or transport temperature limits.
Quality inspection is described as 100% production-line inspection, laboratory sampling and testing, and incoming raw-material inspection. CHUNG PAK also lists ISO 9001:2015 and IATF 16949:2016 certifications. Neither the inspection description nor the certification entries provide a specific operating temperature range for this battery.

| Evaluation Item | Available Data and Required Action |
|---|---|
| Operating temperature range | Not specified; request documented minimum and maximum operating temperatures. |
| Charging and storage temperatures | Not specified; request separate charging and storage limits. |
| Product characteristics | High capacity, cycle life, low self-discharge rate, no memory effect, high safety standards, and environmental consideration. |
| Inspection process | 100% production-line inspection, laboratory sampling and testing, and incoming raw-material inspection. |
| Procurement terms | Minimum order quantity of 10,000 units; listed delivery time of 30 days. |
What operating temperature range should I require for this battery?
The supplied product data does not provide a temperature range. Require CHUNG PAK to state the tested operating limits for the specific battery configuration and application.
Can the battery be approved using its listed safety characteristics alone?
No. High safety standards and the other listed characteristics do not replace a documented operating temperature range. Temperature limits should be confirmed separately.
Which applications should be checked against the temperature requirement?
Check the intended use in equipment such as flashlights, searchlights, portable speakers, industrial sensors, emergency lights, camping lanterns, electronic toys, and portable medical devices listed in the application data.
Require a supplier-confirmed operating temperature range before approving the USB Rechargeable Battery. Keep charging and storage limits as separate information requests because the supplied data does not state them. CHUNG PAK supports distribution and direct sales, with a minimum order quantity of 10,000 batteries and a listed delivery time of 30 days.
