Automatic CR17450 Battery Production Line
In a clean, dust‑free modern workshop with controlled humidity and precision environmental systems, multiple automatic CR17450 battery production lines operate 24 hours a day to boost production capacity and energy efficiency. As a widely recognized standard size, all core materials used in the production process — including electrodes, separators, and electrolytes for 3.0 V lithium‑ion CR17450 battery — are mature and stable to ensure the highest levels of reliability, performance, and safety throughout the manufacturing process.
CR17450 Different current discharge curves (25℃)
This graph illustrates the discharge curves of a CR17450 battery tested at a constant ambient temperature of 25°C. It details the voltage response and total capacity yield across four different constant-current discharge rates: 100mA, 20mA, 5mA, and 2.5mA, all with a strict cutoff voltage of 2.0V. As expected, the data demonstrates that lower discharge currents (2.5mA and 5mA) maximize the cell’s usable capacity, pushing past 2500 mAh. Conversely, the higher 100mA drain rate results in a slightly lower total capacity of approximately 2100 to 2200 mAh due to internal resistance and voltage sag.
CR17450 Discharge curves at different temperatures (20mA to 2.0V)
This graph illustrates the discharge curves of a CR17450 battery tested at various ambient temperatures (-20°C, 0°C, 25°C, and 60°C) under a constant 20mA load with a 2.0V cutoff. The data clearly demonstrates the direct relationship between operating temperature and battery performance. At elevated temperatures (60°C), the cell exhibits a higher operating voltage plateau and maximizes capacity yield, approaching 2500 mAh. Conversely, sub-zero environments (-20°C) increase internal resistance, resulting in a lower initial voltage plateau (approximately 2.6V) and a reduced total capacity yield of roughly 1900 to 2000 mAh.
CR17450 Pulse Discharge Characteristics at Various Temperatures (0.9A)
This graph details the pulse discharge performance of a CR17450 battery across three distinct ambient temperatures (-20°C, 25°C, and 60°C). Unlike continuous drain tests, this evaluates the cell under a heavy, intermittent load: a 0.9A (900mA) draw for 3 seconds, followed by a 27-second rest period. The x-axis represents the total frequency (number of cycles) achieved. The data indicates that at 25°C and 60°C, the battery easily sustains a high voltage plateau (between 2.6V and 2.8V) for over 2500 cycles. At -20°C, the high-current pulse combined with cold-induced internal resistance causes a notable voltage drop (averaging around 1.8V), yet the cell still successfully delivers approximately 1800 to 1900 cycles before depletion.
Title: CR17450 Discharge Characteristics: Fresh vs.
This graph illustrates the capacity retention and voltage stability of a CR17450 battery by comparing a fresh cell against one subjected to accelerated aging (stored at 60°C for 200 days). Both cells were discharged at a constant 20mA to a 2.0V cutoff. The data demonstrates exceptional shelf-life characteristics. Even after prolonged exposure to elevated temperatures, the aged cell exhibits only a marginal drop in its operating voltage plateau and retains the vast majority of its original capacity, yielding approximately 2300 mAh compared to the fresh cell’s ~2400 mAh. This minimal degradation highlights the battery’s robust internal chemistry and long-term storage reliability.
