The Tianneng TNEP12-66 battery is a sealed VRLA-AGM battery designed for deep discharge and applications involving frequent charge cycles. It is intended for electric bicycles and scooters, tricycles and motorcycles, as well as other devices that require an uninterrupted power supply. At 50% DoD, it delivers 1,100 cycles.

Its patented design makes efficient use of the battery’s active materials and internal space. The plate grid reduces internal resistance and helps ensure a uniform electrochemical reaction, while the grid alloy provides corrosion resistance. The safety valve reduces water loss during charging and discharging and improves sealing. The battery requires no water or acid top-ups during use.
