Products Information

Compared with traditional VRLA battery, self-maintenance VRLA has features as follow:

Long service life

Variety of rare earth element have been added to the internal grids, which will result in a 25% rise in service life. The enhanced grid will become somewhat immune to corrosion.

Green and environment protection

The laminated sealing tech will 100% insulate acid leakage of batteries and effectively prevent the acid fog from polluting environment.

High reliability

It adopts advanced assembly technology combining with precise quality management system to improve the shock resistance of the batteries and effectively avoid failures caused by cold solder or false solder or vibration during transportation and use.

Small internal resistance and high homogeneity

It adopts clapboards with special fine fibers to expand the reaction area of positive and negative plates, which greatly reduce the internal resistance of the batteries and avoid rising resistance caused by the reduction of fatigue durability during using.

It adopts (50-60KPS) assembly pressure to effectively minimize the abnormal increase of internal resistance of the batteries that is caused by the reduction of plate group pressure after acid filling

The high equality of internal resistance greatly improves the homogeneity of storage batteries in use.

Features and use of self-maintenance VRLA batteries

Low self-discharge

The use of analytically pure sulphuric acid electrolyte and reasonable arrangement of special additives can effectively reduce the self-discharge speed of the batteries.

High safety

The efficient safety valve made of imported rubber is durable, ageing resistant and corrosion resistant that can effectively ensure the safety of internal pressure of the products in use.

Strong temperature adaptability

It can be safely used between -30oC and 50oC.

Safe and easy for use and transportation

They are manufactured with full load of charges containing no dissociated electrolytes. There is no need of using packages for dangerous goods. And the land and water transportation meet the standards of international shipment.

Economical and practical

The extrmely high performance, long service life and low maintenance combined to make UTK batteris as the most economical and practical products for the users
