Please note that the NCR18650GA batteries I have chosen to use are somewhat of an exception to the Button Top Only rule. While technically they have flat tops, this particular model uses a flat top that extends ‘just a little’ past the insulation wrap like a button top does. That makes this battery compatible with spin-top lights like the SP36, Q8, etc. If a light uses a non-conductive collar around the positive contact as its means of Reverse Polarity Protection, well, I have no way of saying if this one will work or not, as the positive contact is wide and not all that tall.
