Product details
The B.B. Battery EP33-12 standard-type battery is a representative product in the EP series of Valve Regulated Lead Acid (VRLA) batteries. Batteries in this series are offered in 12-volt monobloc form, with capacities spanning a broad range from 7 to 100 Ah, and are designed to meet a variety of demanding applications. The EP33-12 battery fully embodies the core advantages of the series: it uses advanced Absorbent Glass Mat technology to achieve an efficient gas recombination process, thereby ensuring that the battery is completely Maintenance Free throughout its service life, with no water topping-up required by the user. Its structural design completely eliminates free acid, making it a truly leak-proof battery and significantly enhancing safety and convenience in use.
The durability of this battery begins with its robust case, which is made of impact-resistant ABS plastic; the battery cover is firmly joined to the case, and the terminal area is sealed, ensuring the reliability of the overall structure. During production, electrolyte is filled through six dedicated holes in the battery cover, after which pressure relief valves made of non-flammable material are installed. These pressure relief valves not only ensure a high level of fire and explosion safety but are also one of the keys to the battery's Maintenance Free characteristics. Both the positive and negative plates are coated with a specially formulated paste, which, combined with the design, gives the battery excellent high-cycle capability. Under normal conditions of use, EP series batteries can provide a cycle life of up to 2000 cycles, making them ideal for applications requiring frequent charging and discharging.
The EP33-12 battery performs well in terms of technical parameters, with a nominal voltage of 12V. In terms of capacity, it reaches 33 Ah under standard 20-hour rate discharge conditions, 28.05 Ah at the higher 5-hour rate, and can also provide reliable power support of 16.5 Ah at the 30-minute rate, which demands instantaneous high power. The battery's physical dimensions are compact, with length, width, and height of 195 mm, 129 mm, and 155 mm respectively (total height 179 mm), and a Weight of approximately 11.5 kg, making it easy to integrate into various devices. Its installation flexibility is another highlight: the battery can be safely installed in horizontal and vertical positions and is even permitted to be used in any orientation provided it is not inverted, offering great freedom for the internal space layout of equipment. The Terminal Type is standard B7, and the position is rationally designed for easy connection.
Based on its high power output, long cycle life, and reliable safety design, the EP33-12 battery is well suited to a variety of high-load cyclic scenarios. It is a reliable core for uninterruptible power supply systems and backup power for telecommunication facilities, ensuring the continuity of critical business and communications. In the field of medical equipment, its stability and Maintenance Free characteristics are crucial. At the same time, it is also an ideal power source for mobile devices such as wheelchairs, electric bicycles, electric scooters, and golf carts, and can reliably provide lasting power for garden tools such as lawn mowers. In summary, the B.B. Battery EP33-12 standard-type battery combines long service life, considerable capacity, excellent safety, and installation flexibility, providing an efficient and stable power solution for a wide range of industrial and commercial applications.
