6 Key Factors to Consider<\/h2>\n\t\t\n<\/div>\n
\n \t\t\t

Choosing the right battery cells requires understanding these critical parameters. Each factor impacts performance, cost, and reliability of your final product.<\/p>\n\t\t\n<\/div>\n\n<\/div>\n

\n
\n
\n \t\t\t\u26a1<\/span>\n\t\t\t\t\t

Capacity (mAh\/Wh)<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

Determines how long your device can run. Measured in milliamp-hours (mAh) or watt-hours (Wh). Higher capacity = longer runtime, but also larger size and weight.<\/p>\n\t\t\n<\/div>\n\n<\/div>\n

\n
\n \t\t\t\ud83d\udd25<\/span>\n\t\t\t\t\t

Discharge Rate (C-Rate)<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

Indicates how fast the battery can deliver power. Measured in C-rates (1C = full capacity in 1 hour). High-drain devices need higher C-rates (10C-50C). Consumer devices typically use 1C-3C.<\/p>\n\t\t\n<\/div>\n\n<\/div>\n

\n
\n \t\t\t\ud83c\udf21\ufe0f<\/span>\n\t\t\t\t\t

Operating Temperature<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

Battery performance varies with temperature. Standard range: -10\u00b0C to +60\u00b0C. For extreme environments, consider low-temperature or high-temperature variants. JHY offers -20\u00b0C to +80\u00b0C options.<\/p>\n\t\t\n<\/div>\n\n<\/div>\n

\n
\n \t\t\t\ud83d\udccf<\/span>\n\t\t\t\t\t

Form Factor & Size<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

Choose between polymer (flexible, ultra-thin 0.4mm), cylindrical (18650, 21700, 26650), or prismatic cells. Consider space constraints and mechanical requirements of your design.<\/p>\n\t\t\n<\/div>\n\n<\/div>\n

\n
\n \t\t\t\ud83d\udd04<\/span>\n\t\t\t\t\t

Cycle Life<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

Number of charge-discharge cycles before capacity degrades to 80%. JHY cells offer 2000-3000+ cycles. Medical devices need higher cycle life (5000+ cycles) for reliability.<\/p>\n\t\t\n<\/div>\n\n<\/div>\n

\n
\n \t\t\t\ud83c\udfe5<\/span>\n\t\t\t\t\t

Certifications & Standards<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

Medical devices require ISO 13485. Consumer electronics need UL\/CE. Industrial applications may need RoHS, REACH compliance. JHY holds all major certifications.<\/p>\n\t\t\n<\/div>\n\n<\/div>\n\n<\/div>\n\n<\/div>\n\n<\/div>\n
