is also a good practice to placea piece of tape near the connector.
Cut the leads short if they are too high above the main board back, such as the can
inductor leads, CN4 leads. Stick 3 or 4 pieces of thicker tape on the main board. Place a
piece of thin hard card between the tape and the battery to prevent it from touching the
main board.
Never connect the wrong battery polarity! The pin near the enclouser side wall is "-".
