1. Non-cadmium design, environment-friendly: Chilwee Battery has adopted internationally leading technology-container formation non-cadmium production technology, which is in the leading position in the industry. It helps to save energy 28.5%, save water 90%, and non-discharge of waste water

2. Super Long Voyage Ability: The discharge time of Chilwee battery is prolonged. Active additive has been added in postive plates, so as to good consistency of the formated active material. This enables the battery has high charge/discharge efficiency, and the power output is elevated. Discharge time of Chilwee battery is prolonged

3. Strong Motive Power: Super thin plate design is adopted to increase the area of the plates macroscopic electrochemical reaction, which enables the battery has excellent large current discharge ability. Adopting cast-weld process to reduce the battery's internal resistance, and it improves battery charging acceptance capability. Battery's charge/discharge efficiency is high.

4. High Durability: The Chilwee battery has excellent cycle life which can reach 600 cycles @ 80% DOD. The battery banks has good consistency. Enhanced ABS material has been adopted on battery container and lid, and the battery is well sealed to prevent leakage.

5. High Reliability and Safety: Improved negative material prescription and increased micropoles structure at negative helps to improve a lot on low temperature charge/discharge performance. Low water loss rate, high temperature resistance, and the pressure value of Open/Close safety valve is accurate to prevent battery bulging. Safety valve and acid filter can efficiently prevent sparks splashed into battery to ensure safe operation.
