FAQ
1. Which battery is suitable for cold storage equipment?
Selection depends on minimum operating temperature, load current, required runtime and charging conditions. UltraXel offers NCM and LiFePO₄ cells and custom battery packs for cold storage AGVs, emergency lighting and barcode scanners.
2. Can your batteries operate at −40°C?
Selected cells support discharge down to −40°C. For example, HL18650V delivers approximately 70% of its nominal capacity at −40°C under specified test conditions. Actual runtime depends on equipment power consumption and cutoff voltage.
3. Can the batteries be charged inside a cold room?
Selected UltraXel cells support charging down to −20°C under specified conditions. Charging current and temperature limits depend on the cell model. Pack-level temperature monitoring, charging controls or heating may be required for cold storage applications.
4. How long do cold storage batteries last?
UltraXel wide-temperature batteries are designed to provide 5+ years of service life in extreme environments. Actual service life depends on the cell model, charging frequency, depth of discharge, and operating conditions.
5. How do I determine the required battery capacity?
Provide the equipment’s power consumption, continuous and peak current, minimum operating voltage and target runtime. Battery sizing should account for low-temperature capacity, conversion efficiency and aging margin.
6. Can you customize cold storage battery packs?
Yes. UltraXel supports cell selection, series-parallel configurations, PCM/BMS, NTC sensors, wiring, connectors and enclosures. Share your equipment specifications, operating temperature, charging conditions and available installation space for an application review.
