Good day. I have such a problem, DNA-250C cannot fully charge the batteries. I want to analyse the battery, but the program writes that I would wait for a full charge. I left it to charge overnight, and it did not reach 100%. I charged the batteries in an external charger, the device says it is 100% charged. EScribe doesn't want to run the battery test anyway. Batteries 2 cells (Sony vtc6) have been in use for about a year.
