Long Cycle Life
The VTCBATT 574040 3.7V 1200mAh lithium polymer battery is engineered for durability and stable performance. It delivers excellent cycle life under standard 0.5C charge and 1C discharge conditions. The battery retains over 80% of its initial capacity after 500 cycles and supports a total cycle life of up to 1000 cycles. This long cycle life ensures consistent energy output and enables 2–3 years of operation without battery replacement, making it ideal for sealed or maintenance-free battery applications.
Temperature Performance
The VTCBATT 574040 3.7V 1200mAh lithium polymer battery can reliably and continuously discharge over a wide temperature range of -20°C to 60°C. This broad operating temperature range ensures that the battery can power your device in both low and high-temperature environments.
Discharge Rate Custom
The 574040 3.7V 1200mAh LiPo battery and other VTCBATT’s lipo batteries support flexible discharge rates of 0.2C, 0.5C, 1C, 2C, and up to 3C, allowing it to adapt to varying power demands. This wide range of discharge capabilities ensures stable output for both low-power and high-current applications, meeting diverse energy consumption requirements with reliable performance.
PCB with NTC Temperature Protection
The 574040 3.7V 1200mAh LiPo battery is equipped with a PCB integrated with an NTC (Negative Temperature Coefficient) thermistor for precise temperature sensing. As the temperature rises, the NTC resistance decreases, enabling accurate real-time temperature monitoring. This function allows the system to respond promptly to abnormal thermal conditions, significantly enhancing battery safety, reliability, and overall operational stability.
