  • Product Details

W-TEL-GFM valve-regulated lead-acid battery is a high-capacity battery of

new model that is developed with the latest modern technology. Its performance can meet the

standard given in YD/T799-2002 and IEC. This product has many advantages, such as, safe and

reliable seal, high specific energy, low resistance, low rate of self-charge, good charge receptivity,

long cycle life, high seal reaction efficiency. There is no redundant electrolyte in normal use, and no acid smog spray. With easy usage and maintenance, it is intended for service in telecom system, UPS, fire alarming and security system, emergency light system, mobile measuring equipment, power supply system, apparatus and instrument, military facilities, railway transportation and auto control equipment.

Lead-Acid system features

1.Battery case and lid are made of high-strength ABS in a compact structure, characterized by the good resistance to impact and vibration.

2.Grid plate is made of special lead-based multi-element alloy, having virtues of low resistance, and good corrosion-resistance for a long cycle life of battery.

3.New process of plate production are applied to improve the utilization of active material.

4.Ultra fine fiberglass separator with low resistance is used to achieve a good performance in discharging with large current.

5.High-purity electrolyte and special additive are used to reduce the internal resistance of the battery.

6.Multi-layer seal technology and special seal glue are applied to ensure the safety and reliability of battery with no leakage and no acid smog spray.
