Product details
B.B. Battery's BP26-12 is a 12V valve - regulated sealed lead - acid battery. Its outer shell is made of durable and impact - resistant ABS plastic, ensuring the physical safety of the battery during daily use and installation. The battery cover is tightly connected to the shell, and the terminal area is specially sealed to effectively prevent electrolyte leakage and intrusion of external contaminants. The six filling holes on the top are used to fill the electrolyte during production. A pressure relief valve made of non - combustible material is then installed, providing a high level of fire and explosion safety protection for the battery, enabling it to operate stably in various environments.
The nominal capacity of this battery is 26.0 Ah, which is measured under the condition that it is discharged at a 20 - hour rate to a cutoff voltage of 1.75V per cell. Its design takes into account the requirements of various discharge rates. For example, the capacity is 24.7 Ah at a 10 - hour rate and 22.1 Ah at a 5 - hour rate, which provides flexible power support for different load scenarios. The battery has an extremely low self - discharge rate, less than 3% per month, which means that even after long - term storage, it can still maintain a sufficient amount of electricity and is very suitable for backup power applications. Its maximum discharge current can reach 390 amps within 5 seconds, showing excellent instantaneous high - power output capability, while the maximum charging current is 7.8 amps.
The BP26-12 battery offers great flexibility in installation, supporting both vertical and horizontal mounting methods, thanks to its sealed and spill-proof design with no free electrolyte inside. With a compact design, it measures 175 mm in length, 166 mm in width, and 125 mm in height, with a total weight of approximately 9.4 kg, making it easy to integrate into various equipment cabinets or spaces with limited room. The standard terminal is type B1, equipped with M5 bolts and nuts, with an initial tightening torque of 2.5 Nm ± 5%. Users can also choose T2 or I1 as optional terminal types according to actual connection requirements.
In terms of electrical performance, the battery has detailed constant current discharge characteristic data at 25°C.For example, under different cut-off voltages, it supports continuous discharge from 5 minutes to 20 hours, with a wide current range, reliably handling both short-time high-current and long-time low-current discharges. This makes it excellent in applications requiring a backup time of 30 minutes or longer, fully meeting its positioning as a reliable backup power source. Its operating temperature range is wide: 0°C to 40°C for charging, -20°C to 50°C for discharging, and storage temperature of -20°C to 40°C, adapting to various climate conditions from cold to hot.
According to the Eurobat standard, under normal use and maintenance conditions, the BP series batteries have an expected service life of 8 to 10 years. This is due to the paste coating process used for both positive and negative plates, ensuring long cycle life and stable performance. BP26-12 is an ideal choice for low-power uninterruptible power supply systems and is also widely used in telecommunications systems, distribution boards, security alarm systems, medical equipment, photovoltaic energy storage systems, and emergency lighting.In addition, it is also suitable for backup or primary power supply scenarios in the power industry, mining, oil and gas, rural real estate, hotels and shops, and electric vehicles, etc. It is a maintenance-free, safe, reliable, and highly adaptable energy storage solution.
