Turning the charger off each time I changed any charger connections seemed to solved the 'connection break' error problem for me. I connected the AC power supply via a switched power bar so that I could use the power bar switch to turn it off each time before connecting/disconnecting it from any battery. Hope this helps.
Did you find an answer to fixing this error? Every battery I have throws this when attempting to charge. Thanks.
