Check Your Battery Size Before Ordering

The supplier lists a circumference range of approximately 26–44.5cm (10.2–17.5 inches), although its stated imperial minimum is inconsistent. Measure the circumference of your battery at the intended cover position and verify the measurements against the supplier's current size chart before ordering.

Battery housings vary in shape and mounting position, so compatibility is not guaranteed based on voltage or battery style alone.

Important Safety Information

This cover is an additional protective accessory, not a guarantee that your battery is waterproof. Remove it periodically to check for trapped moisture and allow the battery housing to dry.

For the BAG280 heated model, use the heating function only according to the manufacturer's instructions. Confirm compatibility with your battery, avoid overheating, and do not charge the battery with the cover or heating element fitted unless the manufacturer explicitly permits it. Never use a damaged battery or heating element.
