Product details
B.B. Battery's BPS20-12 is a reliable 12V valve-regulated lead-acid battery belonging to the BPS series. The series has a wide range of capacities, from 5Ah to 230Ah, which can meet various power requirement scenarios. This battery uses a sturdy, durable opaque impact-resistant ABS plastic case. The battery cover is tightly connected to the case, and the terminal area is sealed, ensuring overall structural stability.The six holes on the battery cover are the channels for electrolyte filling during production. After that, a pressure relief valve made of non-flammable materials is installed. This design significantly enhances the battery's fire and explosion protection safety level, giving users greater peace of mind when in use.
Technically, BPS20-12 employs advanced absorbent glass mat (AGM) technology, achieving efficient gas recombination, thus ensuring true maintenance-free operation. Users do not need to regularly add electrolyte, there is no free acid, and it is a leak-proof battery. It has an extremely low self-discharge rate, with monthly capacity loss below 3%, making it highly suitable for scenarios requiring long-term standby or intermittent use.Both the positive and negative plates of the battery are coated with special lead paste, which helps to extend its cycle life. According to Eurobat standards, under normal operating conditions, the BPS series batteries have a design service life of over twelve years, making them long - life batteries. Its nominal capacity is 20.0 Ah at a 20 - hour rate, and the cutoff voltage is 1.75 volts per cell.
Installation flexibility is another prominent advantage of the BPS20 - 12. It supports multiple installation directions, both horizontal and vertical, which greatly facilitates the spatial layout inside the device. Its standard terminal is type B1, which can be connected using M5 bolts and nuts. Additionally, users can choose T2 or I1 type terminals according to actual wiring needs.There are clear specifications for the initial torque of the terminal hardware; for example, the B1 terminal is 2.5 Nm. The internal resistance of the battery when fully charged is approximately 11 milliohms. It can withstand a maximum discharge current of 300 amps for 5 seconds, while the recommended maximum charging current is 6.0 amps. It has a wide operating temperature range: 0 to 40 degrees Celsius during charging, and it can operate in environments ranging from - 20 to 50 degrees Celsius during discharge. The storage temperature is - 20 to 40 degrees Celsius.
The BPS20 - 12 battery is compact in size, with a length of approximately 181 mm, a width of 76 mm, a height of 166 mm, and a total weight of about 6.35 kilograms. Its discharge characteristics are stable, and at 25 degrees Celsius, when discharged at different currents to various cut-off voltages, it can provide long-lasting power support. For example, when discharged at a 20-hour rate with a cut-off voltage of 1.75V, the current can reach 1.000A.
This battery is an ideal choice for standby and main power sources in multiple fields. It is particularly suitable for low-power uninterruptible power supply systems requiring 30 minutes or longer backup time, fire and safety alarm systems, emergency lighting, and monitoring systems. It can also be found in access control, medical equipment, telecommunication facilities, country villa power supply, and hotel, restaurant, and store equipment.In addition, BPS20-12 can play a stable role in power supply networks, the power industry, mining, oil and gas industries, as well as renewable energy fields such as solar and wind energy energy storage systems, and can even serve as an auxiliary power source for electric vehicles. For portable or mobile devices such as fishing lights, lawn mowers, and camcorders, it is also a reliable energy solution. Users can also choose the flame-retardant BPS20-12FR model, whose shell is made of flame-retardant ABS material compliant with UL 94-V0 standards, providing additional protection for application scenarios with higher fire protection requirements.
