Modifying an Off-the-shelf Battery
Safety Note
: Ensure you are wearing eye protection and that you are working away
from other people, as these terminals can ping-off the body of the battery in an
unpredictable way!
Use the pliers to grip along the pin and then gently twist around the weld to snap it:
Modifying Support Pins
The contact should lift away from the battery. Note that both contacts are at the same voltage
(ground), so it does not matter if you accidentally touch the neighboring contact during this
operation.
Trimming the Formed Terminals
Safety Note
: The other two contacts supply the voltage from the battery; you
must
take care not to accidentally short them together as the battery is capable of
supplying quite high currents!
We recommend the use of a simple jig to assist with the removal of the battery contacts. If you
have access to a 3D printer, you can
to print this for yourself, or Ubisense can
supply a printed version for a small fee.
