roughen the surface of both of the cell’s

terminals. This ensures that the conductive

adhesive will bond well with the terminals.

• Cut a 20mm length of the conductive copper

tape and remove the protective backing.

• Place it over one of the cell’s terminals and

then use a small plastic object (like a guitar

pick) to firmly push the conductive tape down

on the terminal (Figure

I

).

• Flip the cell over and repeat the above steps for

the other terminal.

Measure the battery voltage again to ensure it

remains stable and consistent with the reading

before the tape was applied (Figure

J

). If the

voltage is unstable or lower than expected,

repeat the ...
