No maintenance: batteries do not need to add water during the entire life of fluid.

High reliability and long service life, special sealing structure and flame retardant case, does not produce in the course of electrolyte leakage defects.

Weight, volume, high energy, the internal resistance of small, high output power.

Small self-discharge, 20 °C under the monthly self-discharge rate is not greater than 2%.

Man charged the factory, no flow of electrolyte transport safety.

No charge balance, as resistance of individual cells, capacity, consistency of quality float voltage to ensure that the battery during use, no need to balance charge.

Solid copper terminals, easy to install connections, conductive ability.

Computer-aided design and computer control the main production process to ensure consistency of product performance and meet design standards.
