1. Features: The unique formula of Pb-Ca-Sn-Al alloy is used as the grid material, which is resistant to overcharge and over-discharge.

Long storage and service life, minimal self-discharge, and long-lasting and reliable performance.

Precision manufacturing process and strict quality control ensure that the battery is consistent and suitable for different application environments.

Fully sealed and maintenance-free design, no maintenance is required during use.

2. Material: The plate materials are more stable and have the most complete lead-calcium battery plate models.

3. Technology: The sealed maintenance-free technology makes the battery seal better, without daily maintenance, and the bumpy state prevents liquid leakage.

4. Volume: The battery is small in size and has a wide range of applications in life.

5. Application field:WBD GS series (0.4Ah~28Ah) VRLA batteries are designed with AGM(Absorbent Glass Mat) technology and for general application purpose, such as UPS, Emergency lights, Alarm system, Security, Toys,Solar System, Telecom and electrical utilities. With 5 years design life, the batteries comply to the most popular international standards, such as IEC896-2, BS6290-4, Eurobat Guide.
