Product details
The BP26-12, a VRLA battery from the BP series, is a reliable and versatile 12V sealed lead-acid battery. As part of the BP series products under B.B. Battery, this series offers a full range of voltage options from 4V, 6V to 12V, with capacities ranging widely from 1.0 to 230 Ah, capable of meeting power requirements in various scenarios. This battery features a sturdy, opaque, impact-resistant ABS plastic case. The battery cover is firmly connected to the case, ensuring the sealing of the terminal area and effectively preventing electrolyte leakage.Its unique battery cover design includes six filling holes, through which the electrolyte is added during production, followed by the installation of a dedicated pressure relief valve made of non-combustible materials. This design not only achieves maintenance-free operation without the need for regular water replenishment but also provides a high level of fire and explosion safety, giving users greater peace of mind.
The specific technical parameters of BP26-12 are outstanding. Its nominal voltage is 12V, nominal capacity at 20-hour rate is 26.0 Ah, with a corresponding cut-off voltage of 1.75V per cell. The battery weight is approximately 9.4 kg.In terms of electrical performance, its internal resistance after full charge is only 10 milliohms, capable of withstanding a maximum discharge current of up to 390 amps for 5 seconds, while the recommended maximum charging current is 7.8 amps. It has a wide operating temperature range: 0°C to 40°C for charging, -20°C to 50°C for discharging, and -20°C to 40°C for storage, demonstrating good environmental adaptability. The physical dimensions of the battery are 175 mm (length) × 166 mm (width) × 125 mm (height), with a compact design that facilitates installation and space planning.
The terminal configuration offers flexibility. The standard terminal is type B1, connected with M5 bolts and nuts, with an initial tightening torque of 2.N·m ±5%. Additionally, users can choose T2 or I1 as optional terminals according to actual wiring requirements. The initial tightening torque for the I1 terminal is 4.0 N·m ±5%. This design allows the battery to be easily integrated into various devices. The BP26-12 series provides two shell material options: standard ABS and optional flame-retardant ABS. The latter complies with the UL94 V-0 standard, offering additional protection for application scenarios with higher fire protection requirements.
In terms of performance, detailed constant-current discharge characteristic data demonstrate its stable output capability under different discharge times and termination voltages. For example, in a 25°C environment, discharging for 30 minutes with a termination voltage of 10.5 V can provide a current of approximately 29.0 amps.These data provide precise references for system design, ensuring the accuracy of backup time calculations. The battery uses pasted positive and negative plates, combined with a valve - regulated sealed design, giving it an expected service life of up to 8 - 10 years under normal usage conditions, complying with Eurobat's standards for long - life batteries. Its monthly self - discharge rate is below 3%, meaning it can retain more charge during storage.
The BP26 - 12 battery is extremely easy to install, supporting both horizontal and vertical installation orientations, which greatly facilitates the spatial layout inside cabinets or equipment. Its maintenance - free and leak - proof features make it an ideal power solution for numerous key application areas.It is very suitable for low - power uninterruptible power supply systems and is recommended for scenarios requiring 30 minutes or longer backup time. At the same time, it is also a reliable power source for telecommunication systems, distribution panels, security alarm systems, medical equipment, photovoltaic energy storage systems, and emergency lighting equipment. In addition, in related fields such as the power industry, mining, oil and gas, rural real estate, hotels and stores, and electric vehicles, it can also serve as a stable backup or main power source, ensuring the continuous and stable operation of key equipment and systems.
