In addition to inconvenience and obfuscation, there is the potential that the location of the battery near the high temperature heatsink may shorten the lifespan of the cell.

**Solder each lead to a piece of nickle strip, and use a tack-welder to re-anchor each strip to the correct polarity battery surface. Alternatively, simply wrap some electricians tape to re-anchor leads to the terminals, though be mindful, that tape adhesive will weaken over time, leading to possible loose connections. Tack welding is strongly recommended. Upon completing this assembly to your satisfaction, move on to the next step. | **Solder each lead to a piece of nickle strip, and use a tack-welder to re-anchor each strip to the correct polarity battery surface.
