The Slugbandit installation can be taken apart (e.g.) for the Winter but please avoid unreasonably straining any of the parts in the process.
In extremely cold temperatures plastics become brittle so take care not to drop the sections.
Step 1: Unclip the sections.
Step 2: Remove the battery from the Battery Box.
Step 3: Clean the contact fingers with a brush [non wire] or with a damp cloth etc.
