The batteries went bad on this card. I thought it would be easy to open it up and pull batteries out and just put new ones in. The batteries were old and corroded. I have not been able to put the batteries in with success. The card has a board on it that looks good on sautering and wiring. I am sure it may be an easy fit but this card has sentimental value to me.
