ANSI/IEEE battery symbol
IEEE-style multi-cell battery drawn as alternating long and short plates, with polarity marked, for American drawing sets.
In plain English
What does ANSI/IEEE battery mean?
In IEEE-style drawing sets a battery is drawn as alternating long and short lines, the long line being positive, with either several plate pairs or two pairs separated by a dashed line to show that cells are omitted. The device designation is commonly BT or B rather than the IEC letter G.
A simple example
The form appears on station DC schematics, control power drawings and microgrid single-line diagrams in North American projects. This is a convention-specific lookup; the geometry here is independently drawn to explain the connection, and is not a certified reproduction of the standard graphic.
What the drawings help you do
The longer line marks the positive terminal. A dashed gap means additional cells not drawn. The IEEE convention uses BT or B as the device letter; the IEC convention uses G for the same battery concept.

How to read it
- The longer line marks the positive terminal.
- A dashed gap means additional cells not drawn.
Information to show or reference
- State nominal voltage and ampere-hour capacity.
- Mark polarity.
- Cross-reference the battery charger and DC distribution.
A distinction that matters
The IEEE convention uses BT or B as the device letter; the IEC convention uses G for the same battery concept.
