SUNJ battery has a fully sealed design, adopt stainless steel housing, and a wide operating temperature range, making the product safe for use in oil and gas drilling instruments, pipeline inspection instruments (PIG), such as drilling well depth measurement, oil pipeline inspection and other fields.
Downhole batteries are used in equipment with high power requirements under harsh operating conditions (high shock and vibration). These lithium batteries are typically used in extreme oil and gas extraction conditions where power cannot be interrupted.

Downhole batteries features

◆ High Energy Density and Longevity: Leveraging advanced Li-SOCl₂ battery technology, our batteries offer high energy density and extended service life. They maintain stable performance even in extreme temperatures, making them ideal for equipment with high pulse discharge requirements.

◆ Safety and Reliability: All batteries undergo rigorous safety testing, meeting international standards such as ISO 9001, ISO 13485, and UN38.3. Our stringent quality control in design and manufacturing ensures reliability in harsh environments.

◆ Smart Monitoring and Data Analysis: Equipped with intelligent battery management systems, our batteries provide real-time monitoring of key parameters such as capacity, voltage, temperature, shock, and vibration. Software analysis tools enable users to accurately track battery usage and downhole conditions.

◆ Customized Solutions: SUNJ Battery offers full lifecycle customization, from battery design and manufacturing to recycling. Our technical team collaborates with customers to develop the optimal battery solution based on specific application requirements.
