VISUAL DESCRIPTION
This vintage advertisement showcases the Tungstone Accumulator, emphasizing its high amp-hour and watt-hour efficiency. The ad highlights that Tungstone's secret lies in using only pure lead and machine-pasted plates without separators, boasting a remarkable 96% amp-hour efficiency. This means that nearly all of the electrical current put out by the dynamo is effectively stored by the battery—a critical feature for early wireless systems or car dynamos. It underscores how this technology ensures consistent performance even when a vehicle’s dynamo isn't fully charging the battery, providing reliability in maintaining higher energy volumes compared to other batteries at that time.
