In terms of battery longevity, this product delivers outstanding performance. Under rigorous laboratory testing, the battery maintains a highly reliable capacity retention rate even after more than 500 deep charge and discharge cycles (100% DOD). This means that even with a full charge every day, your device will still maintain strong battery life after several years of use. Furthermore, it boasts an extremely low self-discharge rate and no memory effect—allowing you to charge and use it at any time—which significantly extends the service life of your end equipment and saves you long-term battery replacement costs.

Engineered to adapt to diverse regions and complex operating environments worldwide, this battery possesses a broad operating temperature range. Whether in freezing outdoor winter conditions or scorching high-temperature work environments (such as a dash cam inside a car during summer), it maintains stable chemical activity and current output. The excellent thermal resistance and advanced aluminum-plastic film packaging technology effectively prevent the battery from swelling, leaking, or suffering sudden performance drops under extreme temperatures, fully safeguarding your device's power security.
