TIANNENG deep cycle Battery TNEP12-28 12V 28Ah (C20)

The Tianneng TNEP battery series is of AGM technology, specially designed for motive power applications, such as electric bicycles/scooters, electric tricycles, electric motorcycles and other devices that require an uninterrupted power source. The TNEP series represents TIANNENG's most reinforced products and holds over 45% of the electric two-wheeler market in China. 

The TNEP battery series are specially designed for deep discharge with a unique patented design. Thanks to this advanced technology, they achieve exceptional performance, with discharge cycles reaching up to 800 at 50% DoD (Depth of Discharge). This durability makes them ideal for applications that require frequent and intense use, ensuring reliability and long-term performance.

Features and Advantages

• VRLA Maintenance-Free Technology, with no need for water or acid addition during use.

• Long lifespan with 800 cycles at 50% DoD (Depth of Discharge) and excellent recovery capability after deep discharge.

• Patented design for the maximum utilization of active materials as well as the internal space of the battery, offering 5%-10% greater capacity compared to similar products on the market.

• The exceptional structure of the plate grid reduces the internal resistance of the battery and ensures that the electrochemical reaction occurs uniformly across the entire plate.

• Due to its unique alloy, the grid has high corrosion resistance, which increases the battery's lifespan.

• The safety valve reduces water loss during the charging/discharging process and improves its sealing.
