The SUNJ battery adopts a fully sealed design, with a stainless steel shell that is sturdy and durable, and has a wide working temperature range, making the product safe and suitable for oil and gas drilling instruments, pipeline inspection instruments (PIG), such as oil well depth measurement and oil pipeline inspection in mining.

SUNJ's batteries are used in devices that require high power under harsh usage conditions (high impact and vibration). These batteries are typically used in extreme oil and gas extraction conditions where power cannot be interrupted.
