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."

Top view of the Globe No. 5 battery showing the battery terminals. Note that the terminals were not set in the center of the battery, but were almost flush with the back of the battery.

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.
