Purchasing a Cameron Sino Survey Battery
The CS-TES351XL is a new compatible Cameron Sino replacement battery for the verified Testo 350K Analyzer and other devices listed below. It provides 11.1V, 6800mAh and 75.48Wh in Li-ion chemistry. Match both compatible models and OEM references before ordering.
What are mAh and Wh?
mAh expresses battery capacity and Wh describes its stored energy. Runtime depends on the actual device, charging, age and conditions. Do not substitute a voltage, connector or battery chemistry solely on the basis of similar capacity.
Quality & Performance
Cameron Sino manufactures replacement batteries for compatible instruments and equipment. This is a compatible replacement battery, not an original Testo battery. Performance depends on equipment condition and proper charging.
Factory Fresh
iTEKcanada sources new Cameron Sino replacement batteries through the manufacturer supply chain. Production dates and exact shelf life vary by batch and are not guaranteed unless separately confirmed.
