The Tianneng TNE12-125 battery uses AGM technology and is a sealed VRLA battery. It is designed for applications with frequent charge and discharge cycles and does not require water or acid to be added during use.

Its patented design makes efficient use of the internal space and active materials. The plate grid helps reduce internal resistance and ensure a uniform electrochemical reaction, while its alloy provides corrosion resistance. The safety valve limits water loss during charging and discharging and improves sealing.
