TIANNENG deep cycle Battery TNEH12-15 12V 15Ah (C20)

The Tianneng TNEH 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 TNEH series represents TIANNENG's most reinforced products and holds over 45% of the electric two-wheeler market in China. 

The TNEH battery series are specially designed for deep discharge with a unique patented design. Combining materials such as carbon fiber and graphene, they achieve exceptional performance, great resistance to heat and corrosion while at the same time they have high electrical conductivity. Thanks to this advanced technology, they achieve exceptional performance with discharge cycles reaching up to 1450 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 1450 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 evenly 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.

• The unique construction materials provide enhanced performance even at low temperatures.

• The alloy of materials used in its casing significantly enhances heat absorption and prevents battery swelling.
