> Use teflon tape under battery holder at assembly time? If you look at how the battery holder works, that's not viable, alas. Battery outer is upwards and is spring finger contacted. Battery centre is downwards and made to slide on PCB contact. Teflon tape would eithrr block contact r, if a hold was left, would still separate battery from PCB.
