battery / electricity / electric
ELECTRICITY (or battery)
Use "X" handshapes. Tap together twice.
Note: Some people feel that the "B" initialization in the sign below makes this an "English" sign.
For the most part, I agree, but I see it being used quite a bit with deaf kids that use hearing-aids.
The "ASL way" to sign "battery" is to use the sign for electricity.
If you sign "HEARING-AID ELECTRICITY" it is obvious that you are talking about a "hearing-aid battery." So there usually no real need to ever use the initialized version of "battery" shown below.
