NEC Article 480 Standard Test for Storage Batteries

EUROLAB laboratory provides testing and compliance services within the scope of NEC Article 480 standard. Solar photovoltaic systems use storage batteries as alternative power sources at night and when sunlight is not strong enough to generate power.

Emergency and standby systems need accumulators to run the generators that provide power during normal power off. Uninterruptible power supply (UPS) systems in 700.12(C) and 701.12(C) use alternating current (AC) converted to direct current (DC) in large battery banks in battery rooms and then converted back to AC as backup. Unit equipment under 700.12(F) and 701.12(G) requires an accumulator for emergency lighting and exit signs.

The nominal voltage for a battery or cell is the value assigned to a cell or battery of a particular voltage class for proper identification purposes. The operating voltage of the cell or battery may vary above or below this value.

The nominal voltage of the battery or battery is required to indicate the most common cell voltage, which is 2 volts (V) per cell for lead acid systems, 1,2V per cell for alkaline systems, and 3,6 to 3,8V per cell for lithium. Nominal voltages can still vary due to different battery chemistries.
