External and internal TTL converters for the OM SYSTEM / OLYMPUS do not require a battery.

Underwater Technics TTL converters for OM System / Olympus draw a micro-current from the +5V power supply pin on the camera's hot shoe and require no battery.

Micro-current consumption has virtually no impact on the camera's battery capacity.
