Description
VRLA AGM technology means the electrolyte is bound in glass-fibre separators, so the battery needs no water topping up and works in closed cabinets. The high-rate design is made for a short discharge at high current, typical of UPS systems, where the load is held for a few minutes until a generator starts. The range includes EN80-6, EN100-4/6, EN160-4/6 and EN180-6 in 4 V and 6 V versions, as well as the 2 V EN320-2, EN480-2 and EN540-2 for large battery banks. The capacity is given for a 20-hour discharge, so when calculating UPS autonomy on a short discharge, use the manufacturer's discharge current tables. The Very long life class in standby mode reduces the number of battery replacements over the life cycle of the equipment.
How to choose
First determine the voltage of the battery string and the required autonomy, then the number of monoblocks. The 2 V EN320-2, EN480-2 and EN540-2 are suitable where a large capacity of a single string is needed without parallel branches. If the equipment requires 12 V blocks, look at ENL with the ENL100-12 model or FXH at 45–238 Ah for mounting in telecom racks. For small UPS systems at 6 or 12 V, the NP series with a capacity of 1–65 Ah is suitable.

FAQ
What is the service life of EN batteries in standby mode?
By EUROBAT classification, the EN series belongs to the Very long life class, i.e. it is designed for 12+ years of operation in standby mode.
What voltage do EN series monoblocks have?
The series is made in 2, 4 and 6 V. The 2 V EN320-2, EN480-2 and EN540-2 have the highest capacity, while EN80-6 and EN180-6 are rated at 6 V.
What capacity do EN batteries have?
The capacity at a 20-hour discharge is in the range of 86.4–579 Ah depending on the model.
Are EN batteries suitable for cyclic operation in a solar power plant?
The series is designed for standby mode. For frequent charge and discharge cycles, NPC with a capacity of 24–100 Ah is a better fit, as it is made specifically for cyclic operation.
How does EN differ from ENL?
EN has a high-rate design for UPS systems and versions for 2, 4 and 6 V. ENL belongs to general-purpose batteries of 2–12 V with a capacity of 108–518.4 Ah, including a model with front terminals.
