EB20-12 BB Battery 12V20AH for Lawn mowers, Electric bicycles and scooters, Golf carts, Communication facilities, Data processing centers, Electric vehicles
EB20-12 is a VRLA battery in the B.B. Battery EB electric series. Its nominal voltage is 12 V, its nominal capacity is 20 Ah at the 20 hour rate and 15 Ah at the 2 hour rate, and it weighs 6.45 kg. B1 is the standard terminal type, with I1 available as an optional terminal type. The product uses absorbent glass mat (AGM) technology for efficient gas recombination and is maintenance free (no water addition required) with no free acid (leak-proof battery). It is designed for high-power and high-cycle use and can be installed in multiple orientations (do not install inverted). The valve-regulated construction keeps the electrolyte in place without any free liquid, so the battery can be mounted in the orientation that the equipment allows. An explosion-proof filter fitted and a flame arrestor fitted for safety complete the design. Typical applications include uninterruptible power supply, medical equipment, lawn mowers, electric bicycles and scooters, golf carts, communication facilities, data processing centers, electric vehicles, wheelchairs and floor cleaning equipment.

Product details
The EB20-12 is a representative product in the B.B. Battery VRLA EB electric series. As a 12 V monobloc sealed lead-acid battery, it provides reliable, long-lasting power. The battery uses valve-regulated sealed construction and belongs to the low-maintenance class, so users do not need to add electrolyte regularly as they would with a traditional battery. Its core strength is excellent cycle life, reaching up to 1300 deep cycles under normal operating conditions.
The case is made of sturdy impact-resistant ABS plastic that protects the internal structure effectively. The lid is firmly joined to the shell, and the terminal area is specially sealed to prevent electrolyte leakage, achieving a no free acid, leak-proof design. Both the positive and the negative plates carry a special active-material paste coating which, combined with absorbent glass mat technology, improves reaction efficiency, delivers efficient internal gas recombination and further strengthens safety. During production the electrolyte is filled through the six holes in the lid, and the pressure relief valve fitted afterwards is made of non-flammable material that releases internal pressure automatically in abnormal conditions, providing fire and explosion protection.
The EB20-12 also offers installation flexibility, as it can be fitted safely in a horizontal or vertical position, giving more layout options inside equipment. Its terminal configuration is flexible: the standard arrangement is a B1 type terminal at position 7, and users can also choose an I1 type terminal at position 6 to suit different connection needs.
The technical parameters define its performance. The battery has a nominal voltage of 12 V: under 20 hour rate discharge conditions the nominal capacity is 20 Ah, while at the higher-power 2 hour rate it is 15 Ah. It weighs about 6.45 kg (14.22 pounds) and has compact dimensions of 181 millimeters (7.13 inches) in length, 76 millimeters (2.99 inches) in width and 166 millimeters (6.54 inches) in height, with the total height equal to the case height.
This combination of high power output, deep-cycle tolerance and long service life (usually up to 5-7 years) makes the EB20-12 an ideal power supply for many critical devices and mobile tools. It is widely used in uninterruptible power supply systems to provide outage protection for servers and network equipment, and in telecommunications facilities and medical equipment to keep operation uninterrupted. It is also a strong power supply for mobile equipment such as electric bicycles, electric scooters, wheelchairs, lawn mowers and golf carts, meeting their requirements for a reliable, high-cycle power supply.
