Battery symbol

Also called Cell, DC source

A battery stores energy as DC. Each cell is a long plate (positive) and a short plate (negative); two or more cells make a battery.

ANSI / IEEE
IEC 60617 · S00898

What the battery symbol means

A battery stores energy as DC. Each cell is a long plate (positive) and a short plate (negative); two or more cells make a battery.

ANSI and IEC symbols

ANSI / IEEE 315

Long and short plates, the long one positive.

ANSI SVG
IEC 60617S00898

Primary cell. Drawn the same way: long and short plates.

IEC SVG

Where you see it

UPS systems, DC switchgear supplies for breaker tripping, emergency lighting and battery energy storage.

What is written next to it

On a one-line, the battery carries its tag and its ratings: nominal voltage, capacity in Ah, number of cells and autonomy.

What gets checked at commissioning

Before the battery is energised, the test records usually cover: cell voltages, a capacity (discharge) test and the charger float and boost settings. Each check is recorded against the tag, so the system can be handed over with its evidence. See commissioning software.
