Product details
Among numerous backup power solutions, the GB12/70B.B. battery stands out with its excellent reliability and deep cycle performance. As a member of the Zelus GB series, this battery adopts advanced gel electrolyte technology, forming a gel-like and immobile substance by mixing sulfuric acid with silica fume. This unique structure almost completely eliminates the common electrolyte evaporation and overflow phenomena in traditional flooded batteries, thus effectively avoiding the corrosion problems caused by this and significantly enhancing the battery's ability to withstand extreme temperatures, impacts, and vibrations.Its valve adjustment system can safely discharge the gas generated internally, ensuring the stability of use. Unlike traditional wet unsealed batteries, in the GB series batteries, calcium replaces antimony in the lead plates. This change significantly reduces the gas evolution rate while retaining excellent mechanical properties, making the battery more durable.
The GB12/70 battery has a nominal voltage of 12 volts. Its capacity varies depending on the discharge rate: the nominal capacity at a 20-hour rate is 70 Ah, while at a 10-hour rate it is 65 Ah. The battery is designed to meet the needs of flexible installation and can be safely placed in horizontal or vertical positions. Its physical dimensions have been carefully optimized: length is approximately 259.5 mm, width is approximately 172.6 mm, height approximately 200.5 mm, total height approximately 217 mm, overall weight approximately 24 kg (equivalent to 52.91 lbs), making it easy to deploy in various spatial environments. The battery is equipped with standard I2-type terminals, ensuring stable and reliable connections.
In terms of performance, the GB12/70 battery is designed for deep cycle applications, aiming to provide maximum capacity and a long discharge cycle life. Under normal operating conditions, its expected service life can reach 12 years or achieve up to 2500 deep cycles, which meets Eurobat's definition of long-life batteries. Its patented safety valve can precisely control internal pressure, further extending the overall service life of the battery.In addition, the battery exhibits excellent high-temperature stability, mechanical strength, and low acid displacement characteristics. Its deep discharge performance is particularly outstanding, capable of meeting power requirements during critical moments.
With these technical parameters and functional details, the GB12/70B.B. battery has become an ideal power source for numerous key application fields. It is very suitable for uninterruptible power supply systems, fire protection and safety alarm systems, providing continuous power support for security. In emergency lighting and monitoring systems, it can ensure immediate activation when the main power is interrupted. Meanwhile, it is also a reliable backup power source for telecommunication facilities and various electronic medical equipment.For street lighting, traffic lights, golf carts, and floor cleaning equipment, it can provide stable power support. In the field of renewable energy, such as solar and wind energy storage systems, its deep cycle and durable characteristics make it an efficient energy storage unit.
