Our advanced technology enhances MWD/LWD battery solutions.
SUNJ battery offers complete, high performance battery packs designed to meet your specifications.
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.
Using high-quality lithium or alkaline cells specifically designed for the oil and gas industry, we produce downhole battery packs for these systems:
· Measurement While Drilling (MWD)
· Logging While Drilling (LWD)
Downhole Battery Packs Highlights
· Premium lithium/thionyl chloride cells designed for high-temperature performance
· Components engineered to withstand the full temperature range of the battery
· Precision-controlled internal welds and soldering for reliability
· Optimized use of epoxies, encapsulants, heat shrink, and casings tailored to application needs
· Advanced assembly methods for extreme conditions including high heat, vibration, and shock
· 100% new, high-grade components
· Fully tested and certified to UN Manual of Tests and Criteria
