Product details
SH4.5-12 is a 12V integrated B.B. Battery VRLA battery from the SH series, with a power output of 108 to 168 watts per unit, providing stable and reliable energy support for various backup power systems. The battery case is made of sturdy and durable opaque impact-resistant ABS plastic, ensuring physical protection. The battery cover is firmly connected to the case and sealed at the terminal area, effectively preventing electrolyte leakage. The terminal design varies by specific model, with top-mounted terminals facilitating easy installation and connection.During the production process, the electrolyte is filled through six holes on the battery cover, followed by the installation of a dedicated pressure relief valve made of non-combustible materials, which significantly improves the product's fire and explosion safety rating.
In terms of internal structure, both positive and negative plates are coated with a special paste-like coating. Combined with advanced valve-regulated sealing technology, it becomes a truly maintenance-free battery that requires no water addition throughout its service life, contains no free acid, and ensures leak-proof safety. The battery has an extremely low self-discharge rate, with monthly capacity loss below 3%, and can still maintain full charge after long-term storage.Its flexible design allows installation in horizontal or vertical directions, greatly facilitating equipment integration, but invert use is prohibited.
The SH4.5-12 battery is optimized for high-rate discharge scenarios and can provide extremely high specific output power in short-term discharge modes. For example, under the condition of discharging to 1.3V per cell in 15 minutes, its discharge power ranges from 78 to 576 watts per battery. Therefore, it is particularly recommended for scenarios with a backup time not exceeding 60 minutes. Its nominal capacity is 5 Ah at a 10-hour rate, with compact dimensions: length 90mm, width 70mm, total height 106mm, and weight approximately 1.53 kg, making it easy to deploy in space-constrained environments.
Under normal operating conditions, the expected service life of this battery can reach 5 to 7 years. It is classified as a long-life battery under Eurobat standards, and its design life can reach 10 years under certain conditions. Capacity and power performance vary based on different discharge rates (e.g., C2, C5, C10) and different cut-off voltages (e.g., 1.3V/cell or 1.6V/cell).
Based on its reliability and high performance, the SH4.5-12 battery is an ideal power choice for low-power UPS systems, uninterruptible power supplies, fire and safety alarm systems, emergency lighting, monitoring systems, and access control systems.Meanwhile, it is also widely used in medical equipment, as backup power for power grids and the power industry, backup power for rural estates, hotels, and shops, and even for powering electric vehicle-related equipment.
