The Heiniger Sirius replacement lithium-ion battery is a spare power pack for the compatible Sirius clipper. Heiniger also identifies item 709-100 on its Opal battery page, connecting the same part number to those named clipper systems.

Use the exact battery number when selecting a replacement or an additional pack. Matching the listed part avoids relying on the shape of the battery or the brand name alone.

This listing is for the battery component. A charger, complete clipper and additional accessories are not established as included. Battery capacity, charging time and runtime are also not specified on the retrieved accessory pages, so the compatible clipper’s documentation should be used for its operating and charging requirements.
