Hearing Aid Batteries

Globe No. 5 Carbon Hearing Aid Battery

The Globe No. 5 was a 3-volt hearing aid battery used in Globe carbon hearing aids around 1917.

The Globe No. 5 carbon-zinc battery weighed 6.0 oz, and measured 3¾" high by 2 1/16" wide by 1⅛" thick.

The pin spacing was exactly 1" (2.5 cm) with the right pin thicker (⅛") than the left pin (3/32") to preserve correct polarity.

Note: this battery was unusual in that most batteries had the left pin as the thicker one, not the right one.

Front view of the Globe No. 5 battery showing the Globe name and model number (No. 5). The Series box is unreadable due to scuffing.

The inscriptions read: "Globe Earphone Battery for Globe Phones", and "Caution - Never leave switch on when phone is not in use", and "Globe Phone Mfg. Co. - Boston, New York, Philadelphia, Chicago, San Francisco, Los Angeles", and Factory - Reading, Mass."

This provided better stability for hearing aids like the Globe "1917" model since the microphone for that aid was "front heavy" and would fall on its face if stood up.
