We spotted some 12V gel-cell batteries at Northackon's Sugru build night. But only some had safety tags on the positive connectors. Aha, a job for Sugru!
Step 1: Make Sugru Blob
This Instructable is very very simple.
- Take a small piece of Sugru (preferably Red) and roll it into a small blob.
- Place the blob around the battery terminal such that it will be able to slide out one side once set.
- Shape to make it look nice.
Step 2: Clean Fingers
That done, it's time to clean up.
We found that Sugru sticks well... to your hands. After a lot of rubbing with paper towel it does come off, but it's more hard work than moulding the Sugru was in the first place.
Step 3: Wait...
Wait for the Sugru to set.
We were a little impatient so removed the first one too soon and it didn't come away cleanly. The second I left in the garage for a couple of days and forgot about. It was tight on, but came off reasonably cleanly. Quick cleanup of Sugru off the terminal and you've got a nice terminal cap to put on your battery.
We only did the positive ends, but with appropriate coloured Sugru it might be nice to do the negative too.
