Synopsis

Automatic testing made precise and automatic for dry cells and batteries.

This old yet foundational apparatus closes electrical circuits at regular intervals, letting you run multiple tests without constant supervision. It uses a clock-driven mechanism, selective relays, and specialized commutators to control discharge and recharge cycles.

The device is designed to reproduce common test scenarios, such as telephone-style, ignition, and flash-light tests, while also enabling life testing of storage batteries. It records each circuit closure and provides visual indicators for which test is active.

• Automates intermittent testing with a clock and escapement-like drive for reliable timing
• Uses mercury switches, select relays, and master relays to manage many test circuits
• Supports multiple test types, including dry-cell and storage-battery cycles
• Keeps a running count of test cycles and signals active tests with indicator lamps

Ideal for researchers and technicians who need repeatable, hands-off testing of battery performance over time.
