Product details
Among numerous backup power solutions, the GBS12/43.5B.B. battery stands out with its excellent reliability and adaptability. As part of the Zelus GBS series, this battery employs advanced gel electrolyte technology, which immobilizes the electrolyte by mixing sulfuric acid with silica fume to form a stable gel-like substance. This design fundamentally avoids common issues such as electrolyte evaporation, overflow, and the resulting corrosion problems in traditional flooded batteries, while also endowing the battery with stronger environmental tolerance. Its valve regulation system can safely discharge the internal gas generated, ensuring the safety of use.In terms of structure, it uses calcium to replace antimony in the lead plates, retaining the robust mechanical properties of lead-acid batteries while significantly reducing the gas evolution tendency, making the battery more stable and durable.
The nominal voltage of this battery is 12 volts, and its nominal capacity reaches 43.5 ampere-hours at a 100-hour rate, providing long-lasting power support for various application scenarios. With its compact size design (length 197 mm, width 165 mm, height 171 mm) and a weight of approximately 16.1 kg, it enables flexible deployment even in installation environments with limited space. The battery can be safely installed in horizontal or vertical positions, offering users great installation flexibility.Standard-configured Type I2 terminals ensure reliable connection. The battery case is made of durable ABS material and can be optionally equipped with flame-retardant ABS material meeting UL94 V-0 standards to meet application requirements with higher safety specifications.
The core advantage of the GBS12/43.5 battery lies in its deep cycle design and long service life. It can operate stably within a wide temperature range of -20°C to 55°C, adapting to various environments from severe cold to extreme heat. With its extremely low self-discharge rate, with monthly capacity loss below 2%, it ensures the battery remains fully charged even after long-term inactivity.The gel electrolyte completely fills the internal space of the battery, not only allowing generated heat to be smoothly transferred to the case for optimized heat dissipation, but also completely eliminating the possibility of electrolyte stratification, which is key to extending the battery's cycle life. Under normal use and maintenance, its expected float charge service life can reach 12 years, and the cycle life is as high as 2500 cycles, meeting the definition of a long-life battery by Eurobat.
Its powerful performance parameters make it an ideal choice for numerous critical applications. The maximum 5-second pulse discharge current can reach 640 amps, capable of meeting instantaneous high-power demands; while the maximum charging current of 8.7 amps supports efficient energy recharge. The internal resistance is only 8.0 milliohms, helps reduce energy loss and improve efficiency. These characteristics make the GBS12/43.5 battery very suitable for uninterruptible power supply systems, fire and safety alarm systems, emergency lighting and monitoring systems. In the fields of telecommunications facilities, medical equipment, street lighting and traffic lights, it provides uninterrupted and reliable power support. Meanwhile, it is also a powerful power source for mobile equipment such as golf carts and floor cleaning equipment, and plays an indispensable role as an important energy storage unit in renewable energy systems such as solar and wind energy.
